2.6.2 long-format changelogSummary of changes from v2.6.1 to v2.6.2 ============================================ <sri@us.ibm.com> [SCTP] ADDIP: Support for processing ASCONF chunks and respond with ASCONF_ACK chunks. <sri@us.ibm.com> [SCTP] Remove the extra semicolon in sctp_cacc_skip_3_1(). <sri@us.ibm.com> [SCTP] ADDIP: Add sysctl parameter to enable/disable addip. <len.brown@intel.com> [ACPI] If ACPI is disabled by DMI BIOS date, then turn it off completely, including table parsing for HT. This avoids a crash due to ancient garbled tables. acpi=force is available to over-ride this default. http://bugzilla.kernel.org/show_bug.cgi?id=1434 <len.brown@intel.com> [ACPI] In ACPI mode, delay print_IO_APIC() to make its output valid. http://bugzilla.kernel.org/show_bug.cgi?id=1177 <sri@us.ibm.com> [SCTP] Fix to free associations in the accept queue of a one-to-one style listening socket that is closed. <sri@us.ibm.com> [SCTP] Fix the duplicate increment of checksum error counter and counting bad packet errors as checksum errors. <sri@us.ibm.com> [SCTP] Fix overflow in the macros JIFFIES_TO_MSECS/MSECS_TO_JIFFIES when used with large values. <len.brown@intel.com> [ACPI] print_IO_APIC() only after it is programmed http://bugzilla.kernel.org/show_bug.cgi?id=1177 <len.brown@intel.com> [ACPI] "acpi_pic_sci=edge" in case platform requires Edge Triggered SCI http://bugzilla.kernel.org/show_bug.cgi?id=1390 <len.brown@intel.com> [ACPI] fix compiler warning (Andrew Morton) <len.brown@intel.com> [ACPI] prevent ES7000 tweak from breaking i386 IOAPIC (Andrew de Quincey) <sri@us.ibm.com> [SCTP] ADDIP: Support for processing incoming ASCONF_ACK chunks. <shaggy@shaggy.austin.ibm.com> JFS: Avoid segfault when dirty inodes are written on readonly mount Writes to a device may cause a ->write_inode to be called during a read-only mount. JFS needs to check for NULL log in jfs_flush_journal. <len.brown@intel.com> [ACPI] sync with 2.4.23 Re-enable IRQ balacning if IOAPIC mode http://bugzilla.kernel.org/show_bug.cgi?id=1440 Also allow IRQ balancing in PIC mode if "acpi_irq_balance" http://bugzilla.kernel.org/show_bug.cgi?id=1391 <len.brown@intel.com> [ACPI] add warning to thermal shutdown (Pavel Machek) <shaggy@shaggy.austin.ibm.com> JFS: Fix broken return code checking in ACL code <len.brown@intel.com> [ACPI] set APIC ACPI SCI OVR default to level/low http://bugzilla.kernel.org/show_bug.cgi?id=1351 <len.brown@intel.com> [ACPI] replace multiple flags with acpi_noirq -- ala 2.4 <len.brown@intel.com> [ACPI] revert two fixes in preparation for ACPICA merge <len.brown@intel.com> [ACPI] update Linux to ACPICA 20031029 (Bob Moore) Fixed a problem where a level-triggered GPE with an associated _Lxx control method was incorrectly cleared twice. Fixed a problem with the Field support code where an access can occur beyond the end-of-region if the field is non-aligned but extends to the very end of the parent region (resulted in an AE_AML_REGION_LIMIT exception.) Fixed a problem with ACPI Fixed Events where an RT Clock handler would not get invoked on an RTC event. The RTC event bitmasks for the PM1 registers were not being initialized properly. Implemented support for executing _STA and _INI methods for Processor objects. Although this is currently not part of the ACPI specification, there is existing ASL code that depends on the init-time execution of these methods. Implemented and deployed a GetDescriptorName function to decode the various types of internal descriptors. Guards against null descriptors during debug output also. Implemented and deployed a GetNodeName function to extract the 4-character namespace node name. This function simplifies the debug and error output, as well as guarding against null pointers during output. Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to simplify the debug and error output of 64-bit integers. This macro replaces the HIDWORD and LODWORD macros for dumping these integers. Updated the implementation of the Stall() operator to only call AcpiOsStall(), and also return an error if the operand is larger than 255. This preserves the required behavior of not relinquishing the processor, as would happen if AcpiOsSleep() was called for "long stalls". Constructs of the form "Store(LocalX,LocalX)" where LocalX is not initialized are now treated as NOOPs. Cleaned up a handful of warnings during 64-bit generation. Fixed a reported error where and incorrect GPE number was passed to the GPE dispatch handler. This value is only used for error output, however. Used this opportunity to clean up and streamline the GPE dispatch code. <len.brown@intel.com> [ACPI] Update Linux to ACPICA 20031203 (Bob Moore) Changed the initialization of Operation Regions during subsystem init to perform two entire walks of the ACPI namespace; The first to initialize the regions themselves, the second to execute the _REG methods. This fixed some interdependencies across _REG methods found on some machines. Fixed a problem where a Store(Local0, Local1) could simply update the object reference count, and not create a new copy of the object if the Local1 is uninitialized. Implemented support for the _SST reserved method during sleep transitions. Implemented support to clear the SLP_TYP and SLP_EN bits when waking up, this is apparently required by some machines. When sleeping, clear the wake status only if SleepState is not S5. Fixed a problem in AcpiRsExtendedIrqResource() where an incorrect pointer arithmetic advanced a string pointer too far. Fixed a problem in AcpiTbGetTablePtr() where a garbage pointer could be returned if the requested table has not been loaded. Within the support for IRQ resources, restructured the handling of the active and edge/level bits. Fixed a few problems in AcpiPsxExecute() where memory could be leaked under certain error conditions. Improved error messages for the cases where the ACPI mode could not be entered. <len.brown@intel.com> [ACPI] delete old _TRA code formerly used just by IA64. (Bjorn Helgaas) The current approach is to walk the _CRS in pcibios_scan_root() using acpi_walk_resources(). <len.brown@intel.com> [ACPI] /proc/acpi files appear in /proc if acpi=off (Shaohua David Li) <len.brown@intel.com> [ACPI] set acpi_disabled=1 on failure for clean /proc http://bugzilla.kernel.org/show_bug.cgi?id=991 <marcel@holtmann.org> [Bluetooth] Disable credit based flow control by default The credit based flow control must be disabled by default for compatibility with Bluetooth 1.0b devices. This patch makes CFC a session attribute, introduces CFC states and cleans up the CFC logic. <marcel@holtmann.org> [Bluetooth] Always use two ISOC URB's This patch modifies the USB Bluetooth driver to use two ISOC URB's per RX and TX transfer paths. This is needed for in time transfer of SCO audio packets over HCI. <marcel@holtmann.org> [Bluetooth] Add support for the Digianswer USB devices The Digianswer USB Bluetooth devices uses a bRequestType of 0x40 for HCI commands, but the Bluetooth specification says that the correct value is 0x20. This patch sets the needed value according to the vendor and product id's of the Bluetooth device. <marcel@holtmann.org> [Bluetooth] Add support for an old ALPS module This patch adds the specific vendor and product id's for an old ALPS module which don't uses the USB Bluetooth class id. <marcel@holtmann.org> [Bluetooth] Update HCI security filter This patch is a very big update to the HCI security filter. It consists of every forgotten commands/events from Bluetooth 1.1 and also the new parts from the Bluetooth 1.2 specification. <marcel@holtmann.org> [Bluetooth] Support inquiry results with RSSI The Bluetooth 1.2 specification defines a new event for returning inquiry results. This patch converts this event into the standard event and add its information to the inquiry cache. <marcel@holtmann.org> [Bluetooth] Remove USB zero packet option This patch removes the USB zero packet option from the HCI USB Bluetooth driver, because it is useless. It also corrects the config name of the SCO audio support. <marcel@holtmann.org> [Bluetooth] Support for AVM BlueFRITZ! USB This adds a driver for the AVM BlueFRITZ! USB devices. The devices from AVM do not follow the Bluetooth specification part H:2 and thus they need their own driver. <marcel@holtmann.org> [Bluetooth] Correct the module alias for the network family The module alias for PF_BLUETOOTH was placed in the BNEP module, but it has to be in the Bluetooth core module. <marcel@holtmann.org> [Bluetooth] Add module aliases for the Bluetooth protocols This patch adds the missing module alias definitions for the various Bluetooth protocols. <marcel@holtmann.org> [Bluetooth] Update the Kconfig entry for the BlueFRITZ! USB driver The BlueFRITZ! USB driver must use "select" to enable the firmware loader, because the option "enable" is deprecated. <marcel@holtmann.org> [Bluetooth] Add CAPI message transport protocol support This adds support for the CAPI message transport protocol (CMTP) to the Bluetooth subsystem. <marcel@holtmann.org> [Bluetooth] Add missing maintainer entries for the Bluetooth subsystem This patch adds the missing maintainer entries for the CAPI message transport protocol and the BlueFRITZ! USB drivers. <marcel@holtmann.org> [Bluetooth] Improve blacklist handling This patch uses the default ID list to ignore the Broadcom BCM2033 devices without firmware. If it not handles a device or a interface it now returns ENODEV to not fill the kernel log with unneeded errors. <marcel@holtmann.org> [Bluetooth] Support for Broadcom Blutonium This adds a driver for the the Broadcom Blutonium USB devices. The devices with Broadcom chips need a firmware loading sequence before they can work like any other Bluetooth H:2 USB device. <jgarzik@redhat.com> [libata sata_sil] unmask interrupts during initialization Prudent in general, and needed for Adaptec BIOSes. <bcollins@debian.org> [VIDEO]: kbuildify the promcons_tbl and logo source files <marcel@holtmann.org> [Bluetooth] Convert interrupt handlers to use irqreturn_t This patch changes the interrupt routines to make use of the irqreturn_t return values. <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 - iminor(inode).patch get rid of unnecessary iminor(inode) code in watchdog's open and close functions. <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 expect_close.patch Made the behaviour and syntax of expect_close the same for all watchdog-drivers <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 i810-tco.c.nowayout.patch Fix nowayout handling to the way all other watchdog-drivers do it <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 _is_open.patch Make _is_open code consistent for all watchdog-drivers <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 cleanup-spaces-tabs.patch Cleanup of trailing spaces, tabs, ... <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 -ENOIOCTLCMD.patch Make the default return value for the ioctl commands that don't exist = -ENOIOCTLCMD <davidm@tiger.hpl.hp.com> ia64: fix potential deadlocks due to printk() Remove all debug printk() for routines which are called with a runqueue lock held, since those could trigger a deadlock. <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 ib700wdt-version-comment.patch remove "for Linux 2.4.x" in the ib700wdt.c driver <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 amd7xx_tco.module_param.patch Made nowayout a module_parameter <wim@iguana.be> [WATCHDOG] 2.6.0-rc1 spelling-fixes-whether.patch Spelling fixes - whether <davidm@tiger.hpl.hp.com> ia64: Skip zero-length resources in PCI root bridge _CRS. This fixes some ugly messages that used to show up on Tiger and other Intel boxes: alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:02 failed alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:08 failed alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:08 failed alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:08 failed alloc 0xffff-0x0 from PCI IO for PCI Bus 0000:08 failed alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:09 failed alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:0f failed <davidm@tiger.hpl.hp.com> Many files: ia64: Cleanup EXPORT_SYMBOL usage This cleans up the use of EXPORT_SYMBOL in ia64_ksyms.c by moving most of them to the place where the symbol is defined. Ideally, only symbols defined in assembler sources should remain here, but there are some cases where an EXPORT_SYMBOL is missing outside the arch/ia64 tree. I did not change them for now. Also, EXPORT_SYMBOL_NOVERS is obsolete. <akpm@osdl.org> [WATCHDOG] 2.6.0-rc1 amd7xx_tco.c-nowayout.patch Fix compile error in amd7xx_tco.c after latest nowayout change <hch@lst.de> [PATCH] fix inia100 driver John W Fort helped me debugging the brown paperbag bugs, the patch below makes it work. <mikenc@us.ibm.com> [PATCH] Initio 9100u The attached patch adds the cpu_to_le32 calls just in case. It was built against my previous patch. <jejb@mulgrave.(none)> 64 bit updates for Workbit NinjaSCSI driver From: GOTO Masanori <gotom@debian.or.jp> Thanks for your report. I compiled and exactly I saw some warnings on amd64 machine. I checked all warnings, and these warnings are trivial, they can be easily fixed. I attached the patch to fix warnings. Nsp32 is PCI device driver, so it should also work on amd64 architecture. <jgarzik@redhat.com> [libata sata_svr] fix DRV_NAME to reflect actual driver filename <marchand@kde.org> [libata sata_sil] add support for adaptec 1210sa, 4-port sii 3114 <greg@kroah.com> USB: add legotower driver to main usb makefile <greg@kroah.com> [PATCH] USB: add a new pl2303 device id. Thanks to Stefan Verkoyen <stefan.verkoyen@quesd.com> for the information. <david-b@pacbell.net> [PATCH] USB: add goku_udc driver (Toshiba TC86C001 USB device) This patch implements the "USB Gadget" API using the "Goku-S" (TC86C001) full speed usb device controller. It's passed testing with Gadget Zero, g_ether (full CDC Ethernet support), gadgetfs, and most interestingly Alan Stern's "File Storage Gadget" (FSG, talking to Linux or Windows as a usb-storage device) to give the halt processing a good workout. Control-OUT works. Tested mostly on x86, with reported success on MIPS. As well as being directly useful with that hardware, I think this is small and simple enough to be useful as an example of how to write a USB controller driver. (There will be many more controller drivers than gadget drivers, I suspect ...) Please merge this to the next 2.6 release that takes new drivers. Corresponding updates for kbuild and the various gadget drivers will be coming (not in a flood). <david-b@pacbell.net> [PATCH] USB: fix kfree in usb-skeleton.c >> if (dev->bulk_in_buffer != NULL) >> kfree (dev->bulk_in_buffer); > > > Yes that one check can go away. Care to send me a patch? Actually all those checks should go away ... <greg@kroah.com> [PATCH] USB: fix bug in bMaxPower sysfs file, it should be * 2 Also cleaned up the string files. Thanks to Mark Smith for pointing this out. <greg@kroah.com> [PATCH] USB: add test for B4000000 to ir-usb driver to fix build issue on some archs <greg@kroah.com> USB: add gadget serial driver from Al Borchers <nathans@sgi.com> [XFS] Remove debug source file from kernel tree; useless without kdb and dropping it cuts down on merge noise. Simplifies the Makefile too. <nathans@sgi.com> [XFS] Rename pagebuf debug option (ie. pagebuf tracing) into a generic XFS tracing option for the other XFS trace code to use too (once fixed).

It's not strictly necessary, but it does eliminate the need for certain boilerplate in machine-specific support, to ensure it's only running on the right hardware: /* in arch/arm/mach-xxx/MYMACHINE.c */ ... static int __init init_MYMACHINE(void) { if (!mach_is_MYMACHINE()) // often forgotten!! return -EINVAL; ... declare and customize platform devices ... return 0; } arch_initcall(init_MYMACHINE); An init_MYMACHINE() call still exists, but it'd be declared as part of the machine definition. <david-b@net.rmk.(none)> [ARM PATCH] 1710/1: pxa2xx_udc (2/5) mach-pxa/idp.c uses INIT_MACHINE Patch from David Brownell This just makes the IDP initialization code use this initcall, so that it won't run unless it's actually on IDP hardware.

Still not a good name for the usage in SCSI core, but it does not conflict, and matches the other names for the IO completion results (SUCCESS, FAILED, etc., they and others should really be prefixed with at least SCSI). eata does not use the TIMEOUT it defines, but there are enough defines of TIMEOUT that it could be a problem in other drivers.

This doesn't seem very useful, and makes the setup_serial_hcdp() reference unresolved if the serial driver is built as a module. CONFIG_SERIAL_8250_CONSOLE is only selectable if the serial core is built in (SERIAL_8250=y), so this patch makes sure we don't try to call setup_serial_hcdp() unless it is actually built in to the kernel. (I think we should also make HCDP selection dependent on SERIAL_8250_CONSOLE=y in Kconfig; I'll send a separate patch for that since it's not ia64-specific.) <khali@linux-fr.org> [PATCH] I2C: Typo in i2c/busses/Kconfig Another simple patch for your collection. BTW I don't think that i2c-rpx can be used in 2.6 since it relies on an algorithm that hasn't been ported yet. <khali@linux-fr.org> [PATCH] I2C: i2c-rpx.c doesn't need ioports.h nor parport.h One more simple patch... These headers are useless as far as I can see. <khali@linux-fr.org> [PATCH] I2C: New parport bus drivers These are replacements for the i2c-philips-par, i2c-elv and i2c-velleman drivers, as well as for the i2c-old i2c-parport driver as found under drivers/media/video in linux 2.4. My reason for writing them, as already discussed on the sensors and linux-kernel mailing-lists, is that all these drivers basically do the same thing, so I thought it would be easier to maintain a single driver instead of four. As Simon Vogl pointed out that using a direct I/O access (as done in i2c-elv and i2c-velleman) could be prefered over clean parport access (as done in i2c-philips-par) on embedded devices, I finally wrote two drivers instead of one. But both drivers support all devices, it's just a matter of how they are accessed (and wether the driver depends on the parport driver). I made it so that the definition of the adapters (i.e. how to set and get SDA and SCL, basically) is completely separated from the code itself. Thus, adding support for a new adapter is simply adding a new set of data to the definition table, describing how the adapter works, in a single file. This means that all simple parallel port adapters are virtually supported. The i2c-pport driver we have in i2c CVS isn't supported yet because it works a bit differently, but I believe that extending the current driver(s) to support it should be possible (although it can be discussed wether it's worth it). You'll have to pass the type parameter that is correct for your board: 0 = Philips 2 = Velleman 3 = ELV 4 = ADM evaluation board I could only test with my ADM eval board, and it worked OK with both drivers. If they are confirmed to work, we could get rid of all other parallel port i2c drivers in 2.6. *** I think we should mark the i2c-philips-par, i2c-elv and i2c-velleman drivers as "deprecated" in i2c/busses/Kconfig. Is there a standard way to do so (like there is "&& EXPERIMENTAL" for new drivers)?

Each of it has a "valid" boolean (combined together into a bitfield) and a jiffies counter. Eeprom_update_client() is added a new parameter to specify which slice to update. Code updated accordingly. Finally, the read function updates only slices that need to be. The code is heavily inspired from what was done in the CVS driver, of course. Three additional notes: 1* This fixes a bug in eeprom_update_client()'s refresh condition. We used to check jiffies before valid, although jiffies are not defined if valid isn't true. That was already fixed in our CVS driver but for some reason the fix did not go into 2.6 yet. 2* This also skips the update if the read if out of bounds. I think this is the thing to do. 3* It can be discussed wether eeprom_update_client() should take two slice parameters instead of one (start slice, end slice). This would make things slightly faster when consecutive slices are requested. Maybe the code would even be clearer. It wasn't done so far because the CVS driver wouldn't benefit from it (because the EEPROM's contents are split over several "output" files in that version of the driver) but I'll probably give it a try in 2.6. <drb@med.co.nz> [PATCH] USB Storage: patch to unusual_devs.h for Pentax Optio 330GS camera I was unable to get my Pentax Optio 330GSrecognised by the 2.6.0 kernel until I applied the patch below that I found posted some months ago on the German Debian mailing list.

It clears a flag that otherwise will prevent us from sending the clear-halt messages following the reset. as141 is the DMA buffer alignment patch. You asked me to remind you about it eventually.

They're also needed for high bandwidth ISO transfers. It also morphs some existing "too much debug info" urb tracing so it's kicked in by a manual #define EHCI_URB_TRACE. If some generic version of that gets added to usbcore, this sort of debug code can vanish (from all hcds). <david-b@pacbell.net> [PATCH] USB: ehci update: 2/3, microframe scanning This patch is needed to make high bandwidth ISO streams behave, but could resolve some other scanning glitches. Current users of periodic transfers (interrupt transfer modes for hubs, mice, and keyboards) shouldn't even notice this change. It makes the periodic schedule scan handle cases where a given frame's schedule slot reports completions in several different microframes. So far that's been uncommon, but it's typical for high bandwidth iso (or even with busier interrupt trees than this driver has supported yet). It also starts to remove the assumption that each ITD only uses one microframe; but most of those changes are in the next patch. And it fixes a bug where some status bits were mis-interpreted as significant bits in the ITD transfer length. <david-b@pacbell.net> [PATCH] USB: ehci update: 3/3, highspeed iso rewrite This is an updated version of a patch submitted to me from Michal Sojka <sojkam1@fel.cvut.cz>, basically providing a much-needed rewrite of the highspeed ISO support. I updated the scheduling and made it a closer match to how OHCI works; and also tested it a bunch. So far it seems most of the requests for highspeed ISO support have been for realtime data collection -- custom apps, nothing a mainstream kernel would ship with. The USB Video class is now defined; highspeed video will also need these updates. Key changes: - Define an "iso_stream" head for iso endpoints. This acts enough like a QH that endpoint_disable() works. It holds the queue of ITDs, and the endpoint's current schedule state. And it's easy to find (spinlocked array access), no search. - Uses a temporary "itd_sched" while submitting each URB, with not-yet-linked ITDs and request-specific metadata. There's a per-stream cache of ITDs, so resubmitting ISO urbs (to achieve a "ring" of transfers) is typically cheap. - Scheduling for most URBs is almost a NOP: just a sanity check to make sure there's no need to reschedule, and then just link into the schedule at the current schedule slot. (The previous code was a gross hack that didn't even work reasonably with more than two URBs queued.) - Is a reasonable model to use with full speed ISO transfers. (They need additional TT scheduling hooks, most of which are already written but not merged.) - Handles several cases the previous code didn't, including high bandwidth transfers (loads up to 24 MByte/sec) - Has had more testing than the old code, including 20+ hour successful IN+OUT runs, more varied transfer intervals and maxpacket sizes. (Using net2280 and a gadgetfs driver.) So it's worth replacing the existing code with this; there aren't too many rough edges, and it's much more fixable than the previous version. p.s.

The read/write routines from the updated subdrivers are changed so they don't bother to differentiate between transfers that do or do not use scatter-gather. The low-level usb_stor_access_xfer_buf routine will Do The Right Thing regardless, and there probably won't ever be more than a few non s-g calls. (What about filesystem I/O requests to access metadata?) It turns out that in addition to removing some comments and a few tests, this change allowed me to remove the buffer and use_sg arguments passed to the read/write routines as well. So the simplification ended up being a bit bigger than I expected. While writing this patch, I noticed spots in several drivers that still need to be changed -- they slipped past me before. These drivers handle things like READ-CAPACITY or REQUEST-SENSE by copying the data directly to srb->request_buffer, which is obviously wrong if s-g is being used. I'll send in changes next week that convert them to use the usb_stor_set_xfer_buf function.

The old code effectively did this anyway, but with this change it is no longer compiling in the part not used. <andrew.vasquez@qlogic.com> [PATCH] No LUNs detected with qla2xxx / qla2300 The problem is during the removal of the failover and IOCTL code from the scsi-qla2xxx-2.6 tree, one critical piece of code (a one-liner) was inadvertently removed that effectively disables the drivers ability to bind fcports (devices found in the loop or fabric) to the SCSI nexus (h/b/t/l). <robert.olsson@data.slu.se> [PKTGEN]: Fix divide by zero and get integer precision at very short time intervals. <davidm@tiger.hpl.hp.com> ia64: arch/ia64/Kconfig URL update: www.linux-on-laptops.com <eugeneteo@eugeneteo.net> [SUNRPC]: Handle copy_*_user and put_user errors <petri.koistinen@iki.fi> [NET]: Fix linux-on-laptops URL in net driver Kconfig. <yoshfuji@linux-ipv6.org> [NET]: Include sysctl.h in neighbour.h regardless of config. <akpm@osdl.org> [PATCH] SH Merge From: Paul Mundt <lethal@linux-sh.org> Here's a rather large update for SH (this is a bit large mainly since a number of things have piled up, and Linus didn't want any of this during feature freeze time). All of these changes are specific to the SH platform, and as such, shouldn't effect any other platforms. <akpm@osdl.org> [PATCH] kyrofb support From: Paul Mundt <lethal@linux-sh.org> This patch adds support for the Kyro graphics boards (STG4000/PowerVR 3/etc= .) to 2.6. This is a direct port and substantial cleanup / rewrite of the 2.4 driver that's available in the sh64 tree at linux-sh.bkbits.net. Some of the overlay code and the STG4000 bits are still a bit ugly, so be forewarned. <akpm@osdl.org> [PATCH] radeonfb line length fix From: Benjamin Herrenschmidt <benh@kernel.crashing.org> Fix the calculation of screenpitch and line lengths. <akpm@osdl.org> [PATCH] loop: fix hard sector size From: Ben Slusky <sluskyb@paranoiacs.org> We need to set the hardsect_size of the loop device to that of the real device. The loop device advertises a block size of 1024 even when configured over a cdrom. When burning a ext2 on a cd, and mounting it directly, I get: blocksize=2048; when I losetup /dev/loop0 /dev/cdrom, and then try to mount, I get: blocksize=1024; and then misaligned transfer; this results in not being able to read the superblock. The loop device should be changed to export the same blocksize of the underlying device <akpm@osdl.org> [PATCH] loop: fix file refcount leak - Fix an error-path file refcount leak - Remove unnecessary get_file()/fput() pair. - Clean up error handling a little <akpm@osdl.org> [PATCH] bdev: open() changes The first of a series which move us toward blockdev hotplug support. After these we have achieved the following: a) For "normal" (not bdevfs) inodes of block devices we never look at ->i_mapping. b) For the same inodes we only look at ->i_bdev in bd_acquire() where it's used only as "here's what we'd found the last time" sort of cached value. If it's NULL, we just recalculate it. c) Lots of messy expressions had been trimmed down, while we are at it. (a) and (b) allow us to start doing proper block hotplug - we can destroy the association between inode and bdev at any time, unhash bdev in question and have new open() do everything from scratch, without waiting for old opened files to close. The goal is to be able to say "revoke everything over that gendisk"/"revoke that partition" and have it do the right thing. This patch: Where the old code called (block device) ->open(inode, file), use ->open(inode->i_bdev->bd_inode, file). Changes in drivers: * none to those that only used inode->i_bdev and inode->i_rdev in their ->open() (bdev->bd_inode->i_bdev == bdev, so we are OK) * floppy.c and floppy98.c used to call permission(inode, ...) in floppy_open(). Switched to permission(file->f_dentry->d_inode, ...) <akpm@osdl.org> [PATCH] bdev: blkdev_put() cleanup From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> Trivial cleanup in blkdev_put() - replace bdev->bd_inode->i_bdev with bdev. <akpm@osdl.org> [PATCH] bdev: presto conversion From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> presto_journal_close() switched to passing struct presto_file_data * instead of bogus struct file *. The only field of struct file we used to look at was file->private_data and most of the callers allocated on-stack struct file, assigned file.private_data and passed the sucker to presto_journal_close(). Idiocy removed. Looks like they started with case where the data they wanted all along was, indeed, in ->private_data of already available struct file, so they just passed pointer to struct file. And when they found that they need to call it in other places where there was no such struct file, they'd done it the dumb way instead of fixing the prototype... <akpm@osdl.org> [PATCH] bdev: add file.f_mapping From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> New field of struct file - ->f_mapping. We maintain the following: file->f_dentry->d_inode->i_mapping == file->f_mapping for all opened files. <akpm@osdl.org> [PATCH] bdev: switch to f_mapping From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> A lot of places used to use ->f_dentry->d_inode->i_mapping all over the place. Replaced with use of ->f_mapping. For now - just the places where we literally could do search-and-replace. <akpm@osdl.org> [PATCH] bdev: use correct mapping's i_sem From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> In a bunch of places we used file->f_dentry->d_inode->i_sem to protect fdatasync et.al. Replaced with corrent file->f_mapping->host->i_sem - the object we are protecting is address_space, so we want an exclusion that would work for redirected ->i_mapping. For normal files (not coda, not bdev) it's all the same, of course - there we have file->f_mapping->host == file->f_dentry->d_inode and change above is an equivalent transfromation. <akpm@osdl.org> [PATCH] bdev: move i_mapping -> f_mapping conversions From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> More uses of ->i_mapping switched to uses of ->f_mapping - stuff that was not caught by the earlier f_mapping conversion. <akpm@osdl.org> [PATCH] bdev: generic_osync_inode() conversion From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> generic_osync_inode() got an extra argument - mapping and doesn't calculate inode->i_mapping anymore. Callers updated and switched to use of ->f_mapping. <akpm@osdl.org> [PATCH] bdev: bd_acquire() cleanup From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> bd_acquire() made static, switched to returning the block_device it had found. Callers updated. <akpm@osdl.org> [PATCH] bdev: generic_write_checks() cleanup From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> generic_write_checks() had lost the first argument (inode) - it can be calculated from the second one (file). <akpm@osdl.org> [PATCH] bdev: add I_BDEV() From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk> For bdevfs inodes (ones created along with struct block_device by fs/block_dev.c) we have inode->i_bdev equal to &BDEV_I(inode)->bdev (i.e. it's at the constant offset from inode). New helper added for such inodes (I_BDEV(inode)). A bunch of places (mostly in block_dev.c) switched to use of that helper. A bunch of places that used file->f_dentry->d_inode->i_bdev->bd_inode switched to file->f_mapping->host - those expressions are equal whenever the former is valid. <akpm@osdl.org> [PATCH] cramfs: use pagecache better From: viro@parcelfarce.linux.theplanet.co.uk Patch switches cramfs_read() to direct use of pagecache and eliminates all messing with buffer_heads. Fixes the interaction with ramdisk (there set_blocksize() simply killed the ramdisk contents) and gets code less brittle overall. <akpm@osdl.org> [PATCH] raw.c refcounting fix From: viro@parcelfarce.linux.theplanet.co.uk raw.c has a refcounting bug (patch attached). As for the theory... If you have a pathname - use filp_open() or open_bdev_excl() and be done with that. bdget() et.al. are OK only if you really have nothing better than device number and that's a situation that should be avoided unless you really have no choice. Said that, we have the following primitives: * lookup_bdev(): takes a pathname, returns a reference to block_device. * bdget(): takes a number, returns a reference to block_device. * blkdev_get(): takes a reference to block_device and opens it. If open fails - drops the reference to block_device passed to it. * blkdev_put(): takes a reference to block_device and closes it. The reference is dropped. * bdput(): drops a reference to block_device. Note that behaviour of blkdev_get() and blkdev_put() is such that it makes for minimal cleanup code. bd_claim()/bd_release() is the exclusion mechanism - that's what mount, swapon, open with O_EXCL, etc. are using to avoid stepping on each others toes. bd_claim() claims bdev for given owner; if it's already owned and not by the same owner you'll get -EBUSY. bd_release() reverts the effect of bd_claim(). Note that if you claim the thing N times (with the same owner, obviously), you'll need N bd_release() before it stops being owned. raw.c grabbed a reference to bdev only after blkdev_get(). If blkdev_get() failed (e.g. media being absent), you've got an unbalanced bdput(). <akpm@osdl.org> [PATCH] Input: smooth out mouse jitter From: Dmitry Torokhov <dtor_core@ameritech.net> When calculating deltas for touchpads that generate absolute events use average over the last 3 packets to remove jitter <akpm@osdl.org> [PATCH] mousedev PS/@ emulation fix From: Dmitry Torokhov <dtor_core@ameritech.net> correctly perform PS/2 (mousedev) emulation for touchpads generating absolute events (do not stop with the first client) <akpm@osdl.org> [PATCH] input: i8042 suspend From: Dmitry Torokhov <dtor_core@ameritech.net> Add suspend methods to restore original controller state on suspend as some BIOS don't like the state we leave it in.

The original fix called setup_cpu on the boot cpu before all others but that wont work for G5, so we now use cpu affinity calls to enforce it. <akpm@osdl.org> [PATCH] ppc64: correct epoll syscall names From: Anton Blanchard <anton@samba.org> correct epoll syscall names <akpm@osdl.org> [PATCH] ppc64: cp_compat_stat should copy nanosecond fields From: Anton Blanchard <anton@samba.org> Looks like glibc is using stat in some places, so we should modify it to copy the nanosecond fields.

Its now as good as test5 in his tests with this patch. He is also seeing quite large increases (above test5) when IO scheduler barriers are disabled (this patch doesn't do that). Perhaps something is using them too liberally. Anyway, this reverts AS back to defaulting to not anticipate IO for a program that submits its first request (this really hurts find | xargs grep sort of things). I am working on something to fix this up properly. That can go in after 2.6.0 anyway. <akpm@osdl.org> [PATCH] AS: request poisoning From: Nick Piggin <piggin@cyberone.com.au> I have tested this on my disks and cdroms, but they don't represent what all drivers might do.

That constitutes small fixes for 2 WARNs getting triggered. It looks like Prakash's lost interrupt problem was due to as spewing bazillions of warnings, and he must have had his kernel.printk configured not to show them or something. I have to just get final confirmation from him that this final cut of the patch fixes his problem too. <akpm@osdl.org> [PATCH] AS: new process estimation From: Nick Piggin <piggin@cyberone.com.au> This one gathers better statistics about the new process problem. It improves estimation for initial process IO. That is, better calculations for whether it will be worth waiting after a process submits its first read. This is done with a per queue average thinktime and seek time for a second read submitted from a process. When combined with 3/3, numbers are around the same as mm1 for most long lived tasks, but much better for things like the top 4 benchmarks. Probably wants rwhron and the OSDL database guys to give it some testing. test 2.6.0-test9-mm1 2.6.0-test9-mm1-np Cat kernel source during seq read 0:26.89 0:24.75 Cat kernel source during seq write 9:17.80 0:23.48 ls -lr kernel source during seq read 0:11.03 0:14.68 ls -lr kernel source during seq write 0:49.95 0:08.06 contest no_load 143s 0 loads 144s 0 loads contest io_load 193s 40.2 loads 193s 40.1 loads contest read_load 186s 11.6 loads 190s 10.5 loads contest list_load 201s 5.0 loads 200s 5.0 loads pgbench 1 client 31.3TPS 31.5TPS pgbench 4 clients 37.7TPS 37.5TPS pgbench 16 clients 42.1TPS 48.1TPS <akpm@osdl.org> [PATCH] AS: thinktime improvement From: Nick Piggin <piggin@cyberone.com.au> Sometimes a processes thinktime shouldn't be measured on how soon it submits its next request, but how soon any close request is submitted. Some processes, such as those in make -j, find | xargs blah, etc. Should be waited upon even if they never submit another request, because they work with cooperating or child processes. This helps to take that into account. <akpm@osdl.org> [PATCH] AS tuning From: Nick Piggin <piggin@cyberone.com.au> The big regression from deadline is tiobench random reads with TCQ disks, however it is present in -linus as well, and would have been since day 1 of AS, but nobody has complained too loudly. http://developer.osdl.org/judith/tiobench/4CPU/rr.html This problem is probably a distilation of what causes lower database throughput, because I have only ever seen it with TCQ drives, and pgbench and OraSim are actually getting higher throughput here with a non TCQ drive. That is not to say that TCQ is useless, it obviously can provide a very real and significant boost. What I might do in the (near) future is get AS to detect TCQ and turn itself off indefinitely unless/until the a sysfs flag is set, and default that flag to off. This patch changes the AS tunables a bit to be more on par with deadline. It lowers the threshold for random reading processes to be considered unsuitable for anticipation, and it slightly rearranges and comments the "cooperative seek distance" logic. With this patch, AS is now very competitive with deadline on the single IDE and SCSI (non TCQ) disks here. In fact, I don't have any regressions anywhere. Even when TCQ is on, although throughput can be lower, AS still has benefits because of its much better read vs write latency and general tendancy to keep number of outstanding tags smaller. <akpm@osdl.org> [PATCH] PPC32: Export consistent_sync_page.

Without this, there is no way to write to an ATAPI MO drive. This patch has been discussed with Linus and Jens already around test9 time and it was agreed this is the right way to go about it. I have rediffed it against 2.6.0. Compiles, runs, works just fine for me. <akpm@osdl.org> [PATCH] mt rainier support From: Jens Axboe <axboe@suse.de> Following patch adds mt rainier support to the cdrom uniform layer (it works with atapi and scsi/usb). <akpm@osdl.org> [PATCH] ATAPI MO support update From: Jens Axboe <axboe@suse.de> Update the ATAPI MO support code to reflect the reorganisations and cleanups which the Mt Ranier support patch added. DESC cdrom_open fix EDESC From: Jens Axboe <axboe@suse.de> <akpm@osdl.org> [PATCH] Make ppp_async callable from hard interrupt From: Paul Mackerras <paulus@samba.org> Since there are serial drivers (particularly the USB serial driver) that call the line discipline receive_buf and write_wakeup routines at hard interrupt level, I have changed the ppp_async code to cope with that. It now uses a tasklet so that it calls the generic PPP code at soft interrupt level even if its receive_buf and write_wakeup entries are called at hard interrupt level. This patch has been lightly tested here with a keyspan USB serial adaptor and also with the built-in modem on my tibook, which uses the pmac_zilog driver (which hooks into the drivers/serial infrastructure). <akpm@osdl.org> [PATCH] make try_to_free_pages walk zonelist From: Rik van Riel <riel@surriel.com> In 2.6.0 both __alloc_pages() and the corresponding wakeup_kswapd()s walk all zones in the zone list, possibly spanning multiple nodes in a low numa factor system like AMD64. Also, if lower_zone_protection is set in /proc, then it may be possible that kswapd never cleans out data in zones further down the zonelist and try_to_free_pages needs to do that. However, in 2.6.0 try_to_free_pages() only frees pages in the pgdat the first zone in the zonelist belongs to. This is probably the wrong behaviour, since both the page allocator and the kswapd wakeup free things from all zones on the zonelist. The following patch makes try_to_free_pages() consistent with the allocator, by passing the zonelist as an argument and freeing pages from all zones in the list. I do not have any numa systems myself, so I have only tested it on my own little smp box. Testing on NUMA systems may be useful, though the patch really only should have an impact in those rare cases where kswapd can't keep up with allocations... As a side effect, the patch shrinks the kernel by 2 lines and replaces some subtle magic by a simpler array walk. <akpm@osdl.org> [PATCH] CardServices() removal from pcmcia net drivers From: Andres Salomon <dilinger@voxel.net> Replace the various CardServices() calls w/ their pcmcia_* function.

The locking uses one global rwlock that's acquired for read in all kill_fasync calls, and that causes cache line trashing. This is not necessary: if the fasync list is empty, then there is no need to acquire the rwlock. Tests with reaim on a 4-way pIII on STP showed an 80% reduction of the time within kill_fasync. <akpm@osdl.org> [PATCH] O21 for interactivity 2.6.0 From: Con Kolivas <kernel@kolivas.org> A non-critical corner case has come up for interactivity that I believe needs to be addressed. It is only extensive testing and examination that revealed this, as this interactivity work is in maintenance mode. Description: It is possible for a highly interactive task (like X) to cause large latencies in tasks that are less 'niced' (eg negative nice number compared to X which should normally run at nice 0) if they are fully cpu bound. This occurs due to expiration of the cpu bound tasks. This patch addresses this by not reinserting interactive tasks into the active array if there is a better static priority task running but has been placed on the expired array. This causes a substantial reduction in the maximum scheduling latency a task with a less nice value can have. This also has the positive side effect of maintaining better cpu% proportions for tasks of different nice levels. Testers will only be able to discern a difference with highly cpu bound tasks of normal scheduling policy at different nice levels. Test cases are doing something cpu intensive relatively -niced in the presence of an interactive load (eg capturing and encoding video at nice -10 while using X nice 0, or something nice 0 vs nice +10) and so on. Because of the crossover of 10 'nice' levels of dynamic priorities between interactive and cpu bound tasks this patch will have a more noticable effect as the nice difference is greater, especially 11 or more. <akpm@osdl.org> [PATCH] Relax synchronization of sched_clock() From: Ingo Molnar <mingo@elte.hu> - relax synchronization of sched_clock() <akpm@osdl.org> [PATCH] can_migrate_task cleanup From: Ingo Molnar <mingo@elte.hu> - minor can_migrate_task cleanup <akpm@osdl.org> [PATCH] CPU scheduler cleanup From: Ingo Molnar <mingo@elte.hu> - move scheduling-state initializtion from copy_process() to sched_fork() (Nick Piggin) <akpm@osdl.org> [PATCH] sched.c style cleanups From: Ingo Molnar <mingo@elte.hu> - sched.c style cleanups (no code change) <akpm@osdl.org> [PATCH] Make for_each_cpu() Iterator More Friendly From: Rusty Russell <rusty@rustcorp.com.au> Anton: breaks PPC64, as it needs cpu_possible_mask, but fix is already in Ameslab tree. The for_each_cpu() and for_each_online_cpu() iterators take a mask, and noone uses them that way (except for arch/i386/mach-voyager, which uses for_each_cpu(cpu_online_mask). Make them more usable iterators, by dropping the "mask" arg. This requires that archs provide a cpu_possible_mask: most do, but PPC64 doesn't, so it is broken by this patch. The other archs use a #define to define it in asm/smp.h. Most places doing loops over cpus testing for cpu_online() should use for_each_cpu: it is synonymous at the moment, but with the CPU hotplug patch the difference becomes important. Followup patches will convert users. <akpm@osdl.org> [PATCH] Use for_each_cpu() Where It's Meant To Be From: Rusty Russell <rusty@rustcorp.com.au> Some places use cpu_online() where they should be using cpu_possible, most commonly for tallying statistics. This makes no difference without hotplug CPU. Use the for_each_cpu() macro in those places, providing good examples (and making the external hotplug CPU patch smaller).

Since VALIDATE_STATE does 'return' if validation fails, bad things can happen. Thanks to Dawson Engler <engler@stanford.edu> and the Stanford checker for spotting. - remove the calls to lock_kernel() from trident_release() and trident_mmap(). trident_release() appears to be covered by the open_sem, and trident_mmap() is covered by state->sem. - s/TRUE/1/, s/FALSE/0/ <akpm@osdl.org> [PATCH] trident: use pr_debug instead of home-brewed TRDBG From: Muli Ben-Yehuda <mulix@mulix.org> Yet another sound/oss/trident cleanup patch. This one replace the TRDBG debugging macro with the standard pr_debug. Patch is from Eugene Teo <eugene.teo@eugeneteo.net>, slightly modified by me to apply against 2.6.0-rc1-mm1 with the other cleanup patches applied. <akpm@osdl.org> [PATCH] selinux: Add resource limit control From: James Morris <jmorris@redhat.com> This patch adds controls to the SELinux module over the setting and inheritance of resource limits. With these controls, the ability to set hard limits can be limited to specific processes such as login, and when an untrusted process invokes a more trusted program, soft limits can be reset, thereby avoiding failures in the trusted program due to malicious setting of the soft limit by the untrusted process. Roland McGrath provided input and feedback on the patch, which was implemented by Stephen Smalley <sds@epoch.ncsc.mil>. <akpm@osdl.org> [PATCH] selinux: add netif controls From: James Morris <jmorris@redhat.com> This patch adds netif access controls for SELinux, which allows network traffic to be controlled on the basis of associated network interface. Similar functionality was present in earlier SELinux implementations; this is a rework within the constraints of the LSM hooks present in the mainline kernel. <akpm@osdl.org> [PATCH] selinux: Add node controls From: James Morris <jmorris@redhat.com> This patch adds 'node' access controls for SELinux, which allows network traffic to be controlled on the basis of remote address. Like the previous patch, similar functionality was present in earlier SELinux implementations; this is a rework within the constraints of the LSM hooks present in the mainline kernel. <akpm@osdl.org> [PATCH] selinux: Add node_bind control From: James Morris <jmorris@redhat.com> This patch adds a new SELinux access control, node_bind, which can be used to restrict the local IP address to which an application may bind. <akpm@osdl.org> [PATCH] selinux: socket_has_perm cleanup From: James Morris <jmorris@redhat.com> This is a cleanup for the SELinux code, which converts all remaining appropriate socket hooks over to using socket_has_perm(). <akpm@osdl.org> [PATCH] selinux: Add SO_PEERSEC socket option and getpeersec LSM hook. From: James Morris <jmorris@redhat.com> This patch adds a new option for Unix sockets, SO_PEERSEC, and an associated LSM hook, getpeersec. The SELinux handler is also included. The purpose of this is to allow applications to obtain each others security credentials, analagously to the existing SO_PEERCRED option. Examples of use are Security Enhanced D-BUS and Security Enhanced X. This patch was previously approved in principle by David, and has been updated with feedback from Chris Wright and extended to cover all architectures. <akpm@osdl.org> [PATCH] selinux: Add dname to audit output when a path cannot be generated. From: James Morris <jmorris@redhat.com> This patch adds dname to audit output when a path cannot be generated. This makes analysis of SELinux audit logs easier. Patch by Stephen Smalley <sds@epoch.ncsc.mil>. <akpm@osdl.org> [PATCH] selinux: Makefile cleanup From: Stephen Smalley <sds@epoch.ncsc.mil> Use obj-$(CONFIG_FOO) instead of `ifeq'. <akpm@osdl.org> [PATCH] selinux: improve skb audit logging From: James Morris <jmorris@redhat.com> This patch is a rework of the skb audit logging code in SELinux. Rather than relying on skb header pointers, it parses the skb for specific protocols (TCP and UDP for IPv4 at this stage). This is safer for the case of locally generated raw packets, which can be malformed. It also now takes fragmented skbs into account. The new code allows the caller to parse the skb so that parsed information can be more readily re-used. <akpm@osdl.org> [PATCH] Add SEND_MSG and RECV_MSG controls From: James Morris <jmorris@redhat.com> This patch implements two new access controls for SELinux: SEND_MSG and RECV_MSG, providing mediation of network packets based on destination port (IPv4 only at this stage). <akpm@osdl.org> [PATCH] NFS: fix bogus setattr calls From: Trond Myklebust <trond.myklebust@fys.uio.no> If users set the execute bit on a file, and then write to it, remove_suid() causes a flood of SETATTR calls (one per write() syscall) with no arguments to be sent down the wire. The server will in any case clear the suid bit itself without any prompting from us, so the following patch simply filters away all SETATTR requests with empty or unsupported ia_valid fields. <akpm@osdl.org> [PATCH] nfs: Optimize away unnecessary NFSv3 COMMIT calls. Currently, when calling nfs_commit_file(), we check the range argument, and only commit NFS write requests that fall within the given range. This is silly, since all servers use fsync(), to honour a COMMIT call, and so will sync all pending writes to stable storage. The following patch ensures that if at least one NFS write falls within the range specified by the call to nfs_commit_file(), then we commit all outstanding writes on that file. This fixes a sometimes severe inefficiency when combining reads and writes: nfs_wb_page() is used to clear out writes prior to scheduling a read(), and can end up calling COMMIT for each page to be read. <akpm@osdl.org> [PATCH] nfs: Fix an open intent bug From: Trond Myklebust <trond.myklebust@fys.uio.no> The following patch fixes a bug when initializing the intent structure in sys_uselib(): intents use the FMODE_READ convention rather than O_RDONLY. It also adds a missing open intent to open_exec(). This ensures that NFS clients will do the necessary close-to-open data cache consistency checking. <akpm@osdl.org> [PATCH] nfs: Fix readonly mounts From: Trond Myklebust <trond.myklebust@fys.uio.no> The nfs_permission() code needs to check for "local" mount flags such as "ro" *before* it decides to optimize away any permissions tests. <akpm@osdl.org> [PATCH] nfs: Fix a possible client deadlock From: Trond Myklebust <trond.myklebust@fys.uio.no> Fix a bug in the NFS write code whereby writepage() may end up deadlocking on clear_inode(). <akpm@osdl.org> [PATCH] nfs: Fix an Oops in the RPC debug code...

From: Martin Schwidefsky <schwidefsky@de.ibm.com> - audit all 32 bit pointer accesses and make them use compat_ioctl(), because of the necessary conversion on s390 - introduce ULONG_IOCTL() which is used instead of COMPATIBLE_IOCTL() for all ioctls that have their argument encoded in 'arg' instead of the memory pointed to by arg. Same reason as above. - remove most #ifdefs in <linux/compat_ioctl.h>: They don't make any sense if the respective handlers in fs/compat_ioctl.c are not disabled as well and they are potentially harmful (the CONFIG_BLK_DEV_DM e.g. was insufficient). - comment out COMPATIBLE_IOCTL(SIOCSIFBR) and COMPATIBLE_IOCTL(SIOCGIFBR), they appear to require a handler - implement copy_in_user for s390, as needed for many handlers in fs/compat_ioctl.c - get rid of all duplicate stuff in arch/s390/kernel/compat_ioctl.c that is also in fs/compat_ioctl.c <akpm@osdl.org> [PATCH] s390: tlb flush optimization. From: Martin Schwidefsky <schwidefsky@de.ibm.com> On the s/390 architecture we still have the issue with tlb flushing and the ipte instruction. We can optimize the tlb flushing a lot with some minor interface changes between the arch backend and the memory management core. In the end the whole thing is about the Invalidate Page Table Entry (ipte) instruction. The instruction sets the invalid bit in the pte and removes the tlb for the page on all cpus for the virtual to physical mapping of the page in a particular address space. The nice thing is that only the tlb for this page gets removed, all the other tlbs stay valid. The reason we can't use ipte to implement flush_tlb_page() is one of the requirements of the instruction: the pte that should get flushed needs to be *valid*. I'd like to add the following four functions to the mm interface: * ptep_establish: Establish a new mapping. This sets a pte entry to a page table and flushes the tlb of the old entry on all cpus if it exists. This is more or less what establish_pte in mm/memory.c does right now but without the update_mmu_cache call. * ptep_test_and_clear_and_flush_young. Do what ptep_test_and_clear_young does and flush the tlb. * ptep_test_and_clear_and_flush_dirty. Do what ptep_test_and_clear_dirty does and flush the tlb. * ptep_get_and_clear_and_flush: Do what ptep_get_and_clear does and flush the tlb. The s/390 specific functions in include/pgtable.h define their own optimized version of these four functions by use of the ipte. I avoid the definition of these function for every architecture I added them to include/asm-generic/pgtable.h. Since i386/x86 and others don't include this header yet and define their own version of the functions found there I #ifdef'd all functions in include/asm-generic/pgtable.h to be able to pick the ones that are needed for each architecture (see patch for details). With the new functions in place it is easy to do the optimization, e.g. the sequence ptep_get_and_clear(ptep); flush_tlb_page(vma, address); gets replace by ptep_get_and_clear_and_flush(vma, address, ptep); The old sequence still works but it is suboptimal on s/390. <akpm@osdl.org> [PATCH] s390: physical dirty/referenced bits. From: Martin Schwidefsky <schwidefsky@de.ibm.com> this is another s/390 related mm patch. It introduces the concept of physical dirty and referenced bits into the common mm code. I always had the nagging feeling that the pte functions for setting/clearing the dirty and referenced bits are not appropriate for s/390. It works but it is a bit of a hack. After the wake of rmap it is now possible to put a much better solution into place. The idea is simple: since there are not dirty/referenced bits in the pte make these function nops on s/390 and add operations on the physical page to the appropriate places. For the referenced bit this is the page_referenced() function. For the dirty bit there are two relevant spots: in page_remove_rmap after the last user of the page removed its reverse mapping and in try_to_unmap after the last user was unmapped. There are two new functions to accomplish this: * page_test_and_clear_dirty: Test and clear the dirty bit of a physical page. This function is analog to ptep_test_and_clear_dirty but gets a struct page as argument instead of a pte_t pointer. * page_test_and_clear_young: Test and clear the referenced bit of a physical page. This function is analog to ptep_test_and_clear_young but gets a struct page as argument instead of a pte_t pointer. Its pretty straightforward and with it the s/390 mm makes much more sense. You'll need the tls flush optimization patch for the patch. Comments ? <akpm@osdl.org> [PATCH] s390: tlb flush race. From: Martin Schwidefsky <schwidefsky@de.ibm.com> I think I found a potential race in install_page/install_file_pte. The inline function zap_pte releases pages by calling page_remove_rmap and page_cache_release. If this was the last user of a page it can get purged from the page cache and then get immediatly reused. But there might still be a tlb for this page on another cpu. The tlb is removed in the callers of zap_pte, install_page and install_file_pte, but this is too late. I admit that its a very unlikely race but never the less.. I fixed this by using the new ptep_clear_flush function that is introduced with the tlb flush optimization patch for s/390. <akpm@osdl.org> [PATCH] s390: rmap optimization. From: Martin Schwidefsky <schwidefsky@de.ibm.com> while working on my mm patch for s390 I played with rmap a bit, adding BUG statements and the like. While doing so I noticed some room for improvement in rmap. Its minor stuff but anyway... The first observation is that the pte chain array doesn't have holes, meaning that from the pte_chain_idx() of the first array every slot of all following pte chain arrays are full. That is there can't be NULL pointers. The "if (!pte_paddr)" check in try_to_unmap() can be removed and if the loop in page_referenced() is started from pte_chain_idx(pc) then the "if (!pte_paddr)" in page_referenced() can be removed as well. The second observation is that the first pte array of a pte chain has at least one entry. Empty pte chain arrays are always freed immediatly after the last entry was removed. Because of that victim_i can be calculated in a simpler way. Instead of setting victim_i to -1 and then check in each loop iteration against -1 victim_i can just be set to the pte_chain_idx of the first pte chain array. <akpm@osdl.org> [PATCH] rmap page refcounting simplification From: Martin Schwidefsky <schwidefsky@de.ibm.com> Ok, its just the revert of the page_cache_release delta. <akpm@osdl.org> [PATCH] s390: superflous flush_tlb_range calls. From: Martin Schwidefsky <schwidefsky@de.ibm.com> while searching for a s390 tlb flush problem I noticed some superflous tlb flushes. One in zeromap_page_range, one in remap_page_range, and another one in filemap_sync. The patch just adds comments but I think these three flush_tlb_range calls can be removed. <akpm@osdl.org> [PATCH] s390: endless loop in follow_page. From: Martin Schwidefsky <schwidefsky@de.ibm.com> Fix endless loop in get_user_pages() on s390. It happens only on s/390 because pte_dirty always returns 0. For all other architectures this is an optimization. In the case of "write && !pte_dirty(pte)" follow_page() returns NULL. On all architectures except s390 handle_pte_fault() will then create a pte with pte_dirty(pte)==1 because write_access==1. In the following, second call to follow_page() all is fine. With the physical dirty bit patch pte_dirty() is always 0 for s/390 because the dirty bit doesn't live in the pte. <akpm@osdl.org> [PATCH] const vs. __attribute__((const)) confusion From: "H. Peter Anvin" <hpa@zytor.com> Declaring a function to return a const scalar value is pretty meaningless. These functions are really trying to say that they don't alter any external state. Fix that up by using __attribute__((const)), if the compiler supports that. <akpm@osdl.org> [PATCH] sn: Some hwgraph code clean up From: Pat Gefre <pfg@sgi.com> Some hwgraph code clean up <akpm@osdl.org> [PATCH] sn: copyright update From: Pat Gefre <pfg@sgi.com> copyright update <akpm@osdl.org> [PATCH] sn: namespace cleanup: ioerror_dump->sn_ioerror_dump From: Pat Gefre <pfg@sgi.com> namespace cleanup: ioerror_dump->sn_ioerror_dump <akpm@osdl.org> [PATCH] sn: kill big endian stuff From: Pat Gefre <pfg@sgi.com> kill big endian stuff <akpm@osdl.org> [PATCH] sn: kill $Id$ From: Pat Gefre <pfg@sgi.com> kill $Id$ <akpm@osdl.org> [PATCH] sn: remove unused enum From: Pat Gefre <pfg@sgi.com> remove unused enum <akpm@osdl.org> [PATCH] sn: serial update From: Pat Gefre <pfg@sgi.com> Jesse Barnes <jbarnes@tomahawk.engr.sgi.com> <akpm@osdl.org> [PATCH] sn: Kill nag.h From: Pat Gefre <pfg@sgi.com> Kill nag.h <akpm@osdl.org> [PATCH] sn: Kill the arcs/*.h files From: Pat Gefre <pfg@sgi.com> Kill the arcs/*.h files Some general clean up on klconfig.h <akpm@osdl.org> [PATCH] sn: Delete invent.h From: Pat Gefre <pfg@sgi.com> Delete invent.h Delete sgi_if.c Cleaned up some of the NEW/DEL calls <akpm@osdl.org> [PATCH] sn: General code clean up of sn/io/io.c From: Pat Gefre <pfg@sgi.com> General code clean up of sn/io/io.c <akpm@osdl.org> [PATCH] sn: machvec/pci.c clean up From: Pat Gefre <pfg@sgi.com> machvec/pci.c clean up Other clean up related to above <akpm@osdl.org> [PATCH] sn: General clean up of xbow.c From: Pat Gefre <pfg@sgi.com> General clean up of xbow.c <akpm@osdl.org> [PATCH] sn: Remove the bridge and xbridge code -

It also adds a function which maps the old numbers to to new ones to maintain binary backward compatibility. <akpm@osdl.org> [PATCH] v4l: v4l2 update From: Gerd Knorr <kraxel@bytesex.org> This patch is a v4l2 update. Changes: * added new ioctls (VIDIOC_G_PRIORITY, VIDIOC_S_PRIORITY) to give v4l apps priorities for tuning and other controls. Main purpose is that backgrounds applictions like nxtvepg which are fishing informations from /dev/vbi (teletext, epg, ...) can run at lower priority than interactive tv apps and thus the user isn't annonyed with unexpected channel switches. * add a set of helper functions to handle priorities to the v4l2-common module. * minor fixes in the v4l1-compat module. * minor header file fixes. <akpm@osdl.org> [PATCH] v4l: video-buf update From: Gerd Knorr <kraxel@bytesex.org> This patch contains video-buf fixes, mainly remove videobuf_lock() and videobuf_unlock() functions. They are not needed as get_user_pages() locks down the pages anyway. <akpm@osdl.org> [PATCH] v4l: bttv driver update From: Gerd Knorr <kraxel@bytesex.org> bttv driver update. Changes: (1) Added a new, sysfs-based interface to allow access to the bt878 gpio lines from other kernel modules (new bttv-gpio.c file), which fixes alot of problems the old interface has (which still is in bttv-if.c, to be removed in 2.7). (2) moved the i2c code from bttv-if.c to bttv-i2c.c. (3) created a new "struct bttv_core" and moved some of the entries from "struct bttv" to the new one. This is needed for (1) and makes the patch pretty big, althrough there is no actual code changes. (4) first cut for suspend support (S1 works for me). (5) usual batch of new/updated tv card list entries. (6) minor fixes. <akpm@osdl.org> [PATCH] v4l: add infrared remote support From: Gerd Knorr <kraxel@bytesex.org> This patch adds a module with some helper functions to handle infrared remotes using the linux input layer. It doesn't do any useful stuff alone, but the saa7134 and bttv drivers will use that to support the remotes shipped with some TV cards. <akpm@osdl.org> [PATCH] v4l: misc i2c fixes From: Gerd Knorr <kraxel@bytesex.org> This is a collection of misc i2c tv helper module fixes. <akpm@osdl.org> [PATCH] v4l: tuner update From: Gerd Knorr <kraxel@bytesex.org> This is a i2c tuner module update. Changes: * adds support for more tunes (mt2050, atsc, ...) * some reorganization, uses function pointers to branch to different functions for different tuner types. <akpm@osdl.org> [PATCH] v4l: add bttv IR input support. From: Gerd Knorr <kraxel@bytesex.org> This patch adds linux input layer based support for infrared remote controls. It adds two new modules: * ir-kbd-i2c supports i2c-based IR receivers. * ir-kbd-gpio supports IR receivers connected to the bt878 gpio pins. This patch depends on the ir-input patch and the bttv driver update. <akpm@osdl.org> [PATCH] v4l: saa7134 driver update From: Gerd Knorr <kraxel@bytesex.org> This is a saa7134 driver update. Changes: * add infrared remote support. * add support for more TV cards. * misc minor fixes. This patch depends on the ir-input patch. <akpm@osdl.org> [PATCH] v4l: add conexant 2388x driver. From: Gerd Knorr <kraxel@bytesex.org> This patch adds a experimental driver for Conexant 2388x based TV cards. DESC cx88-video compile fixes for older gcc EDESC Fix some gcc-3.xisms. <akpm@osdl.org> [PATCH] Use request_list as indicator that req originated from ll_rw_blk From: Mike Christie <michaelc@cs.wisc.edu>, Jens Axboe <axboe@suse.de> It's cleaner and more correct to look at req->rl to determine whether this request got from the block layer requests lists instead of using req->q. It's handy to always have req->q available, to lookup the queue from the request. <akpm@osdl.org> [PATCH] modules: skip debug sections From: Tom Rini <trini@kernel.crashing.org> Skip debug sections of modules - taking 12 minutes to load the ipv6 module is a bug. :) <akpm@osdl.org> [PATCH] update OProfile maintainer From: John Levon <levon@movementarian.org> Please apply the below and accept patches directly from Philippe for OProfile in the future, as necessary.

From: NeilBrown <neilb@cse.unsw.edu.au> nfsd_setuser was not called until after filehandle lookup was done, so filehandle lookup would use the wrong userid, and so the permission checking in nfsd_acceptable would be bogus. <akpm@osdl.org> [PATCH] kNFSd: Convert error status for failed lookup("..") properly.

Patch follows. <khali@linux-fr.org> [PATCH] I2C: Fix i2c-core.c with DEBUG At the moment, i2c-core.c fails compiling with DEBUG. Following patch should fix that. <khali@linux-fr.org> [PATCH] I2C: Fix i2c busses warnings with DEBUG Two bus drivers (i2c-via and scx200_acb.c) generate warnings when the whole i2c subsystem is compiled with -DDEBUG. Suggested changes follow. <khali@linux-fr.org> [PATCH] I2C: New driver: w83l785ts Here is a patch that adds a new chip driver to Linux 2.6.1 (+ previous patches). The w83l785ts driver handles a single chipset, the Winbond W83L785TS-S. I am the author of the original driver as found in lm_sensors 2.8.3. Wolfgang Ziegler AKA fago made an initial port to Linux 2.6, which I reviewed, and here it is. <khali@linux-fr.org> [PATCH] I2C: Autoselect i2c algos I replaced all dependancies on algos with dependancies on I2C + select algo. There are some cases outside of the i2c subdirectory. Also note that I slightly altered the condition to display the PCILynx comment. I think it's more logical that way. Without it, the user could get the message he/she needs I2C, go to enable it, come back and still not see the option. <greg@kroah.com> [PATCH] I2C: only select I2C_ITE if we are a MIPS system <vojtech@ucw.cz> input: Make scancode for a Sun5 type keyboard one of those not ignored because of protocol nastiness. <greg@kroah.com> [PATCH] I2C: add I2C_DEBUG_CORE config option and convert the i2c core code to use it.

Something like this? <greg@kroah.com> [PATCH] Driver Core: add class_simple support This patch adds a struct class_simple which can be used to create "simple" class support for subsystems. It also adds a class_release() callback for struct class, as it is needed to properly handle the reference counting logic. <greg@kroah.com> [PATCH] TTY: clean up sysfs class support for tty devices This patch ports the existing tty class support to the class_simple interface, saving a lot of code in the process. <greg@kroah.com> [PATCH] Input: add sysfs class support for input devices This patch adds sysfs support for all input devices. It also provides the "device" and "driver" symlink for all Input devices that specify it. <greg@kroah.com> [PATCH] LP: add sysfs class support for lp devices Add sysfs class support for lp devices. Based on a patch from Hanna Linder <hannal@us.ibm.com> <greg@kroah.com> [PATCH] MEM: add sysfs class support for mem devices This adds class/mem/ for all memory devices (random, raw, null, etc.) <greg@kroah.com> [PATCH] MISC: add sysfs class support for misc devices This adds class/misc/ for all misc devices (ones that use the misc_register() function). <greg@kroah.com> [PATCH] OSS: add sysfs class support for OSS sound devices This patch adds support for all OSS sound devices. This patch is based on a work originally written by Leann Ogasawara <ogasawara@osdl.org> <greg@kroah.com> [PATCH] ALSA: add sysfs class support for ALSA sound devices This patch adds support for all ALSA sound devices. The previous OSS sound patch is required for this one to work properly.

One of the things that enabling the extra warnings turn up is errors about the placement of the inline keyword. <akpm@osdl.org> [PATCH] do_timer_gettime() cleanup - Make it static - It is larger and has two callsites: uninline it. <akpm@osdl.org> [PATCH] set_cpus_allowed locking From: Nick Piggin <piggin@cyberone.com.au>, Rusty Russell <rusty@rustcorp.com.au> Prevents a race where sys_sched_setaffinity can race with sched_migrate_task and cause sched_migrate_task to restore an invalid cpu mask. <akpm@osdl.org> [PATCH] module removal race fix From: Rusty Russell <rusty@au1.ibm.com> Vatsa spotted this: you can remove a module while it's being initialized, and that will be bad. Hole was opened when I dropped the sem around the init routine (which can probe for other modules). <akpm@osdl.org> [PATCH] Remove Intel check in i386 HPET code From: Andi Kleen <ak@muc.de> The i386 HPET time setup code would explicitely check for the Intel vendor ID. That is bogus because other chipset vendors (like AMD) are implementing HPET too. Remove this check. <akpm@osdl.org> [PATCH] jbd: start_this_handle() return value fix From: Alex Tomas <alex@clusterfs.com> start_this_handle() returns 0 always. because of this journal_start() may return handle with h_transaction = NULL <akpm@osdl.org> [PATCH] remove old Eicon isdn driver From: Armin <armin@melware.de> The new driver for Eicon ISDN cards is in drivers/isdn/hardware/eicon. The old driver is still in drivers/isdn/eicon and I would like to remove this old driver from the 2.6 kernels. The attached patch removes the references to this driver, but in addition the directory drivers/isdn/eicon should be removed. <akpm@osdl.org> [PATCH] Eicon isdn driver hardware access fix From: Armin <armin@melware.de> It fixes access to hardware memory of wrong size and therefore removes a compiler warning. The hardware trap variable must be read as 32bit value. <akpm@osdl.org> [PATCH] Eicon isdn driver alloc buffer size fix From: Armin <armin@melware.de> - Allocate buffer of correct size. - Fix possible buffer overflow. - Use correct debug level for double registered application. <lcapitulino@prefeitura.sp.gov.br> [BRIDGE]: Fix br_netfilter.c build with CONFIG_SYSCTL disabled <akpm@osdl.org> [PATCH] do_no_page leak fix We leak a page in do_no_page() if pte_chain_alloc fails. <akpm@osdl.org> [PATCH] allow SGI IOC4 chipset support From: jbarnes@sgi.com (Jesse Barnes) The 'depends' directive for SGI IOC4 support is too restrictive. Just make it depend on ia64. <akpm@osdl.org> [PATCH] OSS dmabuf deadlock fix Spotted by From: Christian Borntraeger <kernel@borntraeger.net> dma_reset_input() takes dmap->lock, so call it without that lock held. <akpm@osdl.org> [PATCH] Remove redundant code in workqueue.c From: Rusty Russell <rusty@rustcorp.com.au> It turns out that run_workqueue never has signal_pending(), since setting the handler to SIG_IGN means "don't make zombies, I'm ignoring them". Fix the comment, don't allow the signal, and remove the unused waitpid loop. This also allows simpler conversion of workueues to the kthread mechanism, which uses signals to indicate it's time to stop. <akpm@osdl.org> [PATCH] tridentfb documentation fix From: Bram Stolk <bram@sara.nl> Fixes for Documentation/fb/modedb.txt and Documentation/fb/tridentfb.txt <akpm@osdl.org> [PATCH] Optimize proc_pid_lookup From: Manfred Spraul <manfred@colorfullife.com> readdir on /proc has two problems: reading all entries is O(N^2), and entries are overlooked if tasks die in the middle of readdir: the readdir implementation remembers the offset into the task list, and if a task (actually: process) that was returned by previous readdir calls exits, then a random entry is dropped. The attached patch fixes the O(N^2) by using f_version to store the pid of the task that should be returned next. This speeds up reading /proc to O(N). Additionally, it mitigates the effects of dying tasks: Tasks are skipped only if the task whose pid is stored in f_version exits, all other task deaths have no effect. Unfortunately the code has a bad worst case behavior: if the targeted task exits and a new task with the same pid is created, then all entries in the task list between old and new position are dropped. This should be rare. <akpm@osdl.org> [PATCH] clarify meaning of bio fields in the end_io function From: Christophe Saout <christophe@saout.de> The intent of these are to clarify the meaning of the bio fields in the bi_end_io function (since we are already mostly there). After these small modifications bio->bi_idx and the corresponding bio_iovec(bio)->bv_offset point to the beginning of the completed data, together with the nr_bytes argument you know exactly what data was finished, e.g. when you can't track it otherwise (or it would be unnecessary expensive). Apart from that it's a nice-to-have. The first mini-patch moves the update of bio_iovec(bio)->bv_offset and ->bv_len after the call of bi_end_io where bi_idx gets updated so they get updated together. Ok with Jens. The second part of the patch modifies the multwrite hack in PIO non- taskfile ide disk code. It modifies the bi_idx field to walk the bios and doesn't reset it correctly before ending the request. The patch uses the segment counter in the request field to correctly restore the bi_idx field before ending the request. Can't possibly break anything since it's working on the local request copy ("scratchpad") anyway. Also does this in legacy/pdc4030.c (similar code). The code modified here is going to die anyway any trying to fix it would be too invasive. Ok with Bartlomiej. <akpm@osdl.org> [PATCH] RTC leaks. From: Russell King, Tom Rini, Dave Jones As plugged in 2.4 recently. Fix some leakage of uninitialised memory to userspace via rtc reads. <akpm@osdl.org> [PATCH] Simplify node/zone field in page->flags From: Matthew Dobson <colpatch@us.ibm.com> This patch does the following: 1) Rename ZONE_SHIFT to NODEZONE_SHIFT. This value is the number of bits to shift page->flags to get the node/zone part of the bitfield. 2) Add a macro called NODEZONE which takes a node number and zone number and returns a 'nodezone', a bitshifted composition of the two. 3) Create page_zonenum & page_nodenum, inline functions to return the node/zone a page belongs to with some simple bit twiddling, no pointer dereferences necessary. 4) Modify page_zone() and set_page_zone() to use the new NODEZONE_SHIFT. 5) Modify memmap_init_zone() & free_area_init_core() to use the new NODEZONE macros. 6) Fix up some comments to reflect the above changes. <akpm@osdl.org> [PATCH] Identify RADEON Yd in radeonfb From: Bernardo Innocenti <bernie@develer.com> Identify a recent Radeon video card in radeonfb. <akpm@osdl.org> [PATCH] Relocation overflow with modules on Alpha From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Larger modules fail to load with the message "Relocation overflow vs section 17", or some other section number. This failure happens with GPRELHIGH relocation, which is *signed* short, but relocation overflow check in module.c doesn't take into account the sign extension. <akpm@osdl.org> [PATCH] ppc32: OF bootwrapper support From: Tom Rini <trini@kernel.crashing.org> Re-add support to the bootwrapper for talking with OF on PReP machines.

Bligh" <mbligh@aracnet.com> Patches are a damned sight easier to read if people use the '-p' option to diff ... this generates output that looks like this: "@@ -323,6 +323,7 @@ void put_dirty_page(struct task_struct *" for each block. This patch simply adds that to the documentation file, in the hope of steering new users in the right direction. <akpm@osdl.org> [PATCH] Kconfig: use range for NR_CPUS From: Adrian Bunk <bunk@fs.tum.de> The 2.6 Kconfig language allows to set the range for integer questions. The patch below adds a range line on all architectures that have a NR_CPUS question except ia64. The help text on ia64 didn't suggest any values. Could someone tell the correct values for ia64 (and if it's only a minimum value of 2)? <akpm@osdl.org> [PATCH] bio documentation update From: Jens Axboe <axboe@suse.de> Although it was an established part of the current bio api, it was never documented that bio_add_page() and merge_bvec_fn() must accept to add at least one page to an empty bio. <akpm@osdl.org> [PATCH] vmscan: initialize zone->{prev,temp}_priority From: Nikita Danilov <Nikita@Namesys.COM> This patch initializes zone->{prev,temp}_priority to DEF_PRIORITY.

That puts the sequential read numbers back to the 2.6.0 values of ~140MB/sec (from the current 2.6.1 values of 14MB/second)... We were triggering I/O of the `ahead' when we hit the last page in the `current' window. That's bad because it gives no pipelining at all. So go back to full pipelining. It's not at all clear why this change made a 10x difference in NFS throughput. <akpm@osdl.org> [PATCH] kconfig: fix menuconfig exit code From: Sam Ravnborg <sam@ravnborg.org> If the user decides to not write the config file out, menuconfig exits with a non-zero code.

All of the latter (usually) provide voltage scaling, while the p4-clockmod driver only offers a variant of frequency scaling. So, warn users if they try out this driver instead. Also, instead of using a local copy, use the speedstep_lib infrastructure for detecting the processor speed. Adding the Pentium-M get_frequency function to that module only costs about 200 bytes in object size. <akpm@osdl.org> [PATCH] suspend/resume support for PIT From: Pavel Machek <pavel@ucw.cz> This adds proper suspend/resume support for PIT. That means that clock are actually correct after suspend/resume. <akpm@osdl.org> [PATCH] Alpha: make prefetch_spinlock() a no-op on UP From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> When CONFIG_SMP is not set, spinlock_t is an empty structure, so its address has arbitrary alignment. The prefetch instructions with unaligned address don't have visible side effects on alphas with SRM console (except performance degradation) - the PALcode handles unaligned traps caused by prefetch instructions internally. However, on old AlphaBIOS/MILO boxes unaligned prefetch leads to unhandled alignment trap and kernel panic. <akpm@osdl.org> [PATCH] Fix statically declare FIXMAPs From: Anton Blanchard <anton@samba.org>, me. Two uses of the FIXADDR_USER_START/END things are problematic: a) ppc64 wants the FIXADDR area to be at a different location on 32bit and 64bit tasks. On 32bit we want it just below 4GB but that gets in the way on 64bit. By putting both right at -(some small amount) we can also use some ppc tricks to get there real quickly (single instruction branches). b) We assume that FIXADDR_USER_START and FIXADDR_USER_END are constants. This breaks the UML build. Fixes: - Call it all gate. We currently have half the stuff called fixmap and the other gate, lets be consistent. - Create in_gate_area(), get_gate_vma() and use it in both places - Provide defaults for in_gate_area/get_gate_vma, allowing an arch to override it. (I used CONFIG_* but am open to better suggestions here) - The /proc/pid/maps vma wasnt marked readable but the get_user vma was. That sounds suspicious to me, they are now both the same VMA and so have the same (read,exec) permissions <akpm@osdl.org> [PATCH] tmpfs readdir does not update dir atime From: mark@borgerding.net Access times of tmpfs dirs do not get updated on readdir.

But for that to happen without rewriting half of XFS (and changing layering in a way that we don't really want) we need an additional fs-private variable in struct block_device. <akpm@osdl.org> [PATCH] ext3: fix determination of inode journalling mode The test for whether an inode is using journalled, ordered or writeback data is incorrect and can lead to ext3_set_aops() giving the inode the wrong set of address_space_operations.

The patch fiddles with the efi_enabled definition to arrange for `efi_enabled' to be constant zero or constant one in those situations where this can be guaranteed. <akpm@osdl.org> [PATCH] make gcc 3.4 compilation work From: David Mosberger <davidm@napali.hpl.hp.com> With gcc-3.4 we need "attribute((used))" declarations to get "make modules_install" to work.

Not a big deal, but every byte helps in the .data segment ;-) <akpm@osdl.org> [PATCH] ppc cond_syscall fix From: Matt Mackall <mpm@selenic.com> Experimenting with trying to use cond_syscall for a few arch-specific syscalls, I discovered that it can't actually be used outside the file in which sys_ni_syscall is declared because the assembler doesn't feel obliged to output the symbol in that case: weak.c: #define cond_syscall(x) asm(".weak\t" #x "\n\t.set\t" #x ",sys_ni_syscall"); cond_syscall(sys_foo); $ nm weak.o U sys_ni_syscall One arch (PPC) is apparently trying to use cond_syscall this way anyway, though it's probably never been actually tested as the above test was done on a PPC. After trying a bunch of tricks to get it to work nicely, I decided there are basically two alternatives: make weak versions of sys_ni_syscall wherever they're wanted or put the arch-specific cond_syscalls in kernel/sys.c where sys_ni_syscall is defined. The former approach is a bit crufty and doesn't actually do the right thing in practice as you'll get multiple copies of sys_ni_syscall in your final image. The latter introduces some slight arch-pollution in sys.c, but as arch-specific cond_syscalls aren't all that frequent, it should be pretty minor. So here's a patch to move the current offender to sys.c: <akpm@osdl.org> [PATCH] cleanup single_open usage in dma.c From: Jeff Muizelaar <muizelaar@rogers.com> The attached patch lets the seq_file api take care of buffer allocation instead of doing it by hand. <petri.koistinen@iki.fi> [IPV4]: Fix URL mentioned for IP_ROUTE_NAT. <akpm@osdl.org> [PATCH] rq_for_each_bio fix From: Xavier Bestel <xavier.bestel@free.fr> Within the body of this macro we are accessing rq->bio, but `bio' is an arg to the macro.

It: (1) Includes Pete's patch to skip the colon in the volume name, compile directly into the kernel, and not try to access non-existent caching routines. (2) Changes if (...) BUG() to BUG_ON() (3) Gets rid of typedefs. (4) Changes list_for_each() into list_for_each_entry(). (5) Adds more whitespace and wraps lines to please the CodingStyle sticklers. <akpm@osdl.org> [PATCH] ALI M1533 audio hang fix From: risto.sandvik@helsinki.fi Everything freezes when trying to play sounds using the alsa driver opl3sa2 (kernel supplied or 1.0.0rc2) on an Acer Extensa series laptop with the Ali M1533 PCI to ISA bridge. Problem exists both in the 2.6 and 2.4 series of kernels. Adding AL_M1533 to drivers/pci/quirks.c fixes the problem for both. This has been a known problem since 2.2.x (see http://www.mfn.unipmn.it/~sitta/linux503.html) <akpm@osdl.org> [PATCH] kbuild: Maintainers update From: Sam Ravnborg <sam@ravnborg.org> Modify MAINTAINERS to reflect the reality in maintainership for kbuild.

Here's a patch which puts it back. <paulus@samba.org> [PATCH] sort exception tables This patch arranges for the exception tables to be sorted on most architectures. It sorts the main kernel exception table on startup and the module exception tables when they get loaded. The main table is sorted reasonably early - just after kmem_cache_init - but that could be moved even earlier if necessary. There is now a lib/extable.c which includes the sort_extable() function from arch/ppc/mm/extable.c and the search_extable() function from arch/i386/mm/extable.c, which had been copied to many architectures. On many architectures, arch/$(ARCH)/mm/extable.c became empty and so I have removed it. There are four architectures which do things differently from i386: alpha, ia64, sparc and sparc64. Alpha and ia64 store the offset from the offset from the exception table entry to the instruction, and sparc and sparc64 have range entries in the table. For those architectures I have added empty sort_extable functions. The maintainers for those architectures can implement something better if they care to. As it is they are no worse off than before. Although it is a moderately sizable patch, it ends up with a net reduction of 377 lines in the size of the kernel source. :) I have tested this on x86 and ppc with a module that uses __get_user in an init function, deliberately laid out to get the exception table out of order, and it works (whereas it oopsed without this patch). <torvalds@home.osdl.org> Make sure we don't access "cmd" in ide-scsi after having started the command - it may not exist any more.

The code propagates data toggle settings between messages in a queue for control transfers just the same as bulk and interrupt transfers. That is a mistake, since control messages always restart with data toggle 0. With this patch, the UHCI driver now passes test 10 (control URB queueing) in David Brownell's usbtest suite. The patch appears to change more than it really does, because it alters the indentation level of a large section of code. <greg@kroah.com> USB: hook up the HID device's struct device to the input system properly. <greg@kroah.com> [PATCH] USB: hook up the other (non-HID) input devices to the input system properly. <akropel1@rochester.rr.com> [PATCH] USB: hiddev HIDIOCGREPORT not blocking in 2.6 I've noticed in 2.6 kernels that HIDIOCGREPORT does not wait for io completion before returning to the caller. This creates a few unpleasant issues for userspace: First, code sequences such as... ioctl(fd, HIDIOCGREPORT, &rinfo); ioctl(fd, HIDIOCGUSAGE, &uinfo); ioctl(fd, HIDIOCGSTRING, &sdesc); ...that used to work in 2.4 now fail in 2.6 if the device takes more than a few milliseconds to respond to HIDIOCGREPORT. (I'm seeing this issue on APC UPSes, FWIW.) Second, userspace code can easily flood the kernel with control messages since the kernel provides no "backpressure". The result is a lot of "hid-core.c: control queue full" errors and lost reports. 2.6 hid-core.c appears to submit the request and return immediately. Although the 2.4 code differs significantly, I traced the call path to usb-core.c, which seems to block with a timeout, so the code supports my userspace observation. (Assuming I didn't misread it.) <stern@rowland.harvard.edu> [PATCH] USB Storage: Notify the SCSI layer about device resets According to James Bottomley, we need to notify the SCSI midlayer whenever we issue a driver-initiated device reset.

The patch below fixes this. <akpm@osdl.org> [PATCH] ppc64: iSeries virtual console From: Stephen Rothwell <sfr@canb.auug.org.au> This is a forward port of a 2.4 driver that has been present in a couple of (enterprise) distributions for some time. It works for me :-), I even get console output :-) This makes the machine almost usable - next we will get virtual disk. It has been considerably tidied up, but if you have any further worries with it, let me know. <akpm@osdl.org> [PATCH] Asus L5 framebuffer fix From: Pontus Fuchs <pontus.fuchs@tactel.se> I need the following patch for radeonfb to work on my Asus L5. See http://bugs.xfree86.org/show_bug.cgi?id=561 for more info. (benh confirmed this with ATI). <akpm@osdl.org> [PATCH] loop needs MODULE_ALIAS_BLOCK From: Erik van Konijnenburg <ekonijn@xs4all.nl> There are two issues here: - absense of a MODULE_ALIAS_BLOCK in loop.c - mismatch between the patterns used in the MODULE_ALIAS_BLOCK define and the modprobe invokation in request_module. (acked by Rusty) <akpm@osdl.org> [PATCH] loop: trivial error number fix From: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> This patch fixes the error number when invalid file is passed (neother S_ISBLK nor S_ISREG is true). We should return -EINVAL. <akpm@osdl.org> [PATCH] One-shot support for epoll From: Davide Libenzi <davidel@xmailserver.org> The attached patch implements the one-shot support for epoll. Because of the way epoll works (hooking f_op->poll()) the ET behavior is not really ET because it might happen that, while data is still available to read (for the EPOLLIN case), another chunk will become available triggering another event. While those conditions can be easily be handled in userspace, the absolute triviality of the patch and the avoidance of user/kernel space switches and f_op->poll() calls, make IMHO worth doing this inside epoll itself. <akpm@osdl.org> [PATCH] RAID-6 From: "H. Peter Anvin" <hpa@zytor.com> RAID6 implementation. See Kconfig help for usage details. The next release of `mdadm' has raid6 userspace support. <akpm@osdl.org> [PATCH] check for truncated modules From: Rusty Russell <rusty@rustcorp.com.au> I *do* want to add a check for a truncated module, since that's probably the most common case (^C on "make modules_install"). But I don't want to double the size of module.c with every check I can think of. tested with: # bs=0; while [ $bs -lt 3764 ]; do dd if=dummy.ko bs=$bs count=1 2>/dev/null | insmod -; bs=`expr $bs + 1`; done <akpm@osdl.org> [PATCH] md: fix return code in set_disk_faulty() From: NeilBrown <neilb@cse.unsw.edu.au> Following are 10 patches for md in 2.6.1-lastest. 1-6 are simple bugfixes that I am confident should be in 2.6.2. 7 is a bugfix that is fairly important, but could probably do with a bit more testing first. It is not impossible that it could deadlock, though I think I have caught and fixed all the problems. 8-10 are code simplication. So maybe 7-10 should only go in -mm for now, but if it is a while before 2.6.2, then maybe they can go in a 2.6.2-pre. From: Mike Tran <mhtran@us.ibm.com> If cannot find the device, return error (ENODEV) Otherwise, return success (0) <akpm@osdl.org> [PATCH] md: Don't allow raid5 rebuild to swamp raid5 stripe cache From: NeilBrown <neilb@cse.unsw.edu.au> raid5 rebuild takes stripes so agressively that other access cannot get a look-in. With this patch, the rebuild pauses slightly if there is a shortage of stripes to let other processes have a chance. akpm: I was worried about starvation due to the harsh semantics of yield() in 2.6. But Neil has performed specific testing for that and things seem OK. If people do note CPU starvation problems we will need to replace the yield() with a schedule_timeout(1). <akpm@osdl.org> [PATCH] md: Make sure an interrupted resync doesn't seem to have completed. From: NeilBrown <neilb@cse.unsw.edu.au> If the raid1 or raid5 thread gets to run md_check_recovery after the recovery thread has been interupted, but before do_md_stop completes, a spare drive can be incorporated into an array befure it is up-to-date. This patch corrects the relevant test. <akpm@osdl.org> [PATCH] md: Fix typo in comment From: NeilBrown <neilb@cse.unsw.edu.au> Thanks dann frazier <dannf@hp.com> <akpm@osdl.org> [PATCH] md: Make sure md recovery happens appropriately. From: NeilBrown <neilb@cse.unsw.edu.au> Currently if there are two failed drives, and two spares are added, then recovery starts onto the first spare, but never notices the second spare. To cope, we set RECOVERY_NEEDED when recovery finishes so that we re-check. <akpm@osdl.org> [PATCH] md: Don't do_md_stop and array when do_md_run fails. From: NeilBrown <neilb@cse.unsw.edu.au> Current code calls do_md_stop to clean up if do_md_run fails, but this is a/ not needed as do_md_run cleans up itself b/ bad as it could try to clean up after an -EBUSY error !!! <akpm@osdl.org> [PATCH] md: Small fixes for timely writing of md superblocks. From: NeilBrown <neilb@cse.unsw.edu.au> Currently a raid0 superblock is only written when the array is stopped, so a crash between creation and stop can lose your data. This patch marks a superblock 'dirty' at creation and forces a dirty superblock to be written when the array is started. Previously we would prod the per-array thread at this point, but as it avoids certain chores when the array is locked, and the array is locked at this point, that isn't guaranteed to do the right thing. Instead we prod the thread whenever the array is unlocked. Finally, only write the superblock at array stop if it is needed to mark the array as 'clean'. raid0 which is never dirty, doesn't need this. <akpm@osdl.org> [PATCH] md: Remove the 'disks' array from md which holds the gendisk structures. From: NeilBrown <neilb@cse.unsw.edu.au> Move the pointers into mddev. The reduces dependance on MAX_MD_DEVS. <akpm@osdl.org> [PATCH] md: Discard the mddev_map array. From: NeilBrown <neilb@cse.unsw.edu.au> We only need it occasionally to map unit number to mddev, and we can use a linear search for that. This reduces dependance on MAX_MD_DEVS <akpm@osdl.org> [PATCH] md: Use bd_disk->private data instead of bd_inode->u.generic_ip From: NeilBrown <neilb@cse.unsw.edu.au> ..to access 'mddev' from the inode pointer. This is already set up for us. <akpm@osdl.org> [PATCH] Move XATTR_SECURITY_PREFIX macro to common location From: Chris Wright <chrisw@osdl.org> Move the XATTR_SECURITY_PREFIX macro to the xattr.h header so that it's in a common location. (Acked by Stephen Smalley) <akpm@osdl.org> [PATCH] Default hooks protecting the XATTR_SECURITY_PREFIX namespace From: Chris Wright <chrisw@osdl.org> Add default hooks for both the dummy and capability code to protect the XATTR_SECURITY_PREFIX namespace. These EAs were fully accessible to unauthorized users, so a user that rebooted from an SELinux kernel to a default kernel would leave those critical EAs unprotected. (Acked by Stephen Smalley) <akpm@osdl.org> [PATCH] Fix x86-64 ptrace From: Andi Kleen <ak@muc.de> The EFLAGS checking was not correct. This also fixes some problems with 32bit gdb who would sometimes make the kernel BUG. <akpm@osdl.org> [PATCH] sendfile calls lock_verify_area with wrong parameters From: Manfred Spraul <manfred@colorfullife.com> sendfile supports reading from a given start offset for in_file, like pread. But for the locks_verify_area call, in_file->f_pos is always used, even if a start offset is used. Result: wrong area is checked for mandatory locks. <akpm@osdl.org> [PATCH] pc300_tty.c is broken From: Russell King <rmk+lkml@arm.linux.org.uk> Russell was unable to correctly migrate this driver to the new modem-control-signal API because TIOCMBIS/TIOCMBIC do not control only the DTR signal, but also the RTS, OUT1 and OUT2 signals, or even maybe nothing at all. Plus, these IOCTLs are no longer passed down to the driver. Instead, drivers should implement tiocmget and tiocmset driver methods. so mark it as broken so as to not break allmodconfig/allyesconfig. <akpm@osdl.org> [PATCH] dbv: update documentation From: Michael Hunold <hunold@linuxtv.org> - update contributors - documentation update for recent DVB TTUSB driver changes <akpm@osdl.org> [PATCH] dvb: update saa7146 driver From: Michael Hunold <hunold@linuxtv.org> - fix memory leak in page table handling - minor coding style changes - add simple resource management for video dmas (borrowed from saa7134) - use resource management to lock video and vbi access which sometimes share the same video dmas - honour return codes of extension functions in various places, when resources could not be locked - remove remains of dead code which were commented out anyway - add new flag FORMAT_IS_PLANAR to indicate planar capture formats, needed for resource allocation <akpm@osdl.org> [PATCH] dvb: update core From: Michael Hunold <hunold@linuxtv.org> - demux: fix nasty bug where setting multiple filters resulted in ts packet duplication - frontend: merge frontend improvements from 2.4 DVB tree: - schedule_timeout(1) in dvb_frontend.c after setting frontend and before waking up frontend thread - do FE_RESET in each iteration of frontend thread if !FE_HAS_LOCK - use aquire_signal flag to call FE_RESET only after tuning until FE_HAS_LOCK has been signalled, and not when FE_HAS_LOCK drops out for short periods of time later - follow frontend changes in ves1x93 driver <akpm@osdl.org> [PATCH] dvb: av7110 driver splitup From: Michael Hunold <hunold@linuxtv.org> - after the firmware removal, split av7110.c into separate modules: - av7110.c: initialization and demux stuff - av7110_hw.c: lowlevel hardware access and firmware interface - av7110_ca.c: CI and ECD - av7110_av.c: audio/video MPEG decoder and remuxing stuff - av7110_v4l.c: v4l interface - av7110 fixes that were notcies during splitup - rename some non-static functions to enhance readability - lots of coding style & whitespace fixes - return -ERESTARTSYS from ci_ll_read/write() if interrupted - use time_after() for timeouts - added some comments about firmware interface - removed some unused fields from struct av7110, retabbing - follow driver splitup in Makefile <akpm@osdl.org> [PATCH] dvb: TTUSB driver update From: Michael Hunold <hunold@linuxtv.org> - TTUSB-DEC update by Alex Woods: - fix USB timeout bug under 2.6 - change some variable names to make it clearer what we are dealing with (PVA). - support DEC2540-t and add info on it to the ttusb-dec docs. - add model number returned from DEC2540-t firmware. - add a module option to get the raw AVPES packets from the dvr device. - send audio packets to their filter rather than the videos. - handle the new empty packets that appear with the 2.16 firmware. - extra error checks. - handle the new firmwares that change the devices' USB IDs. - tidy up the STB initialisation process a little. - apply Hans-Frieder Vogt's patch for calculating firmware CRCs. - make TTUSB budget card depend on USB subsystem <akpm@osdl.org> [PATCH] amd74xx: fix for !CONFIG_PROCFS From: "Randy.Dunlap" <rddunlap@osdl.org> From: Luiz Fernando Capitulino <lcapitulino@prefeitura.sp.gov.br> this patch fixes this warning: drivers/ide/pci/amd74xx.c:80: warning: `amd_udma2cyc' defined but not used when !CONFIG_PROC_FS. <akpm@osdl.org> [PATCH] APM: handle kernel_thread failure From: "Randy.Dunlap" <rddunlap@osdl.org> From: Eugene TEO <eugeneteo@eugeneteo.net> <akpm@osdl.org> [PATCH] MCA: handle bus failure From: "Randy.Dunlap" <rddunlap@osdl.org> From: Eugene TEO <eugeneteo@eugeneteo.net> Handle OOM in mca_init() <akpm@osdl.org> [PATCH] md: fixes for !CONFIG_PROCFS From: "Randy.Dunlap" <rddunlap@osdl.org> From: Luiz Fernando Capitulino <lcapitulino@prefeitura.sp.gov.br> It fixes these warnings when !CONFIG_PROC_FS: drivers/md/md.c: In function `md_geninit': drivers/md/md.c:3481: warning: unused variable `p' drivers/md/md.c: At top level: drivers/md/md.c:3007: warning: `md_seq_fops' defined but not used <akpm@osdl.org> [PATCH] vm overcommit documentation corrections From: "Randy.Dunlap" <rddunlap@osdl.org> From: Patrick McLean <pmclean@linuxfreak.ca> <akpm@osdl.org> [PATCH] spell Unix98 the same everywhere From: "Randy.Dunlap" <rddunlap@osdl.org> From: Andreas Beckmann <sparclinux@abeckmann.de> Patch is for consistency in spelling Unix98 (vs. Unix 98). This matches the other 20 or so occurrences of it. <akpm@osdl.org> [PATCH] md: remove unneeded ifdef/endif From: "Randy.Dunlap" <rddunlap@osdl.org> From: Luiz Fernando Capitulino <lcapitulino@prefeitura.sp.gov.br> This #ifdef/#endif is not necessary. <akpm@osdl.org> [PATCH] remove unused flags arg from fs/stat64* From: "Randy.Dunlap" <rddunlap@osdl.org> From: Michael Still <mikal@stillhq.com> Viro and Andi Kleen agreed. The <flags> argument isn't used at all and cannot be used safely in the future. remove third arg <long flags> from all 3 fs/stat.c stat64() calls since it's not used and there's no way to use it safely; <akpm@osdl.org> [PATCH] correct floppy outb() macro arg names From: "Randy.Dunlap" <rddunlap@osdl.org> This patch changes no code, just swaps macro arg names to match reality. <akpm@osdl.org> [PATCH] ext3: update a_ops when running `chattr +j' From: Jan Kara <jack@suse.cz> Journalled-data files need a different set of address_space_operations, so we need to update the file's aops when someone runs `chattr +j' on the file. <akpm@osdl.org> [PATCH] exception table search fix The exception table search code currently fails if addresses differ by more than 2G. This is only a problem when using the 4g/4g address space split, but it's more robust this way. Also, shuffle the comparison order n there so the least likely case comes last. <akpm@osdl.org> [PATCH] reiserfs: cleanup_bitmap_list() check for NULL argument. From: Nikita Danilov <Nikita@Namesys.COM> fs/reiserfs/journal.c:cleanup_bitmap_list() can be called to cleanup reiserfs_list_bitmap that was only partly initialized. Check that jb->bitmaps array was actually allocated, before trying to free its elements. <akpm@osdl.org> [PATCH] Document problems with USB legacy support From: Vojtech Pavlik <vojtech@suse.cz> <akpm@osdl.org> [PATCH] drivers/isdn/Kconfig URL update: caltech.edu From: Petri Koistinen <petri.koistinen@iki.fi> Little URL fix.

The patch also fixes possible unlock of not locked spin_lock. <akpm@osdl.org> [PATCH] smbfs: remove noisy printk's These printk's come out during normal usage, when accessing locked system files on the windows machines. <akpm@osdl.org> [PATCH] NFS/RPC modprobe -r sunrpc causes an oops From: Steve Dickson <SteveD@redhat.com> Here is a patch for the 2.6.1 kernel that fixes an oops that occurs when the sunrpc module is unloaded. The problem was the RPC cache_register() call was not saving entry pointers to the procfs entries it was creating. So when it came time to dismantle the entires, a BUG_ON() was tripped in remove_proc_entry() since the tree was not broken down completely. (acked by neilb) <akpm@osdl.org> [PATCH] afs: avoid ifdef inside macro expansion From: David Howells <dhowells@redhat.com> Eliminate the printing of the cache token if present: using cpp conditionals inside macro expansions is not legal and some gcc's fail it. <akpm@osdl.org> [PATCH] do not use shared extable code for ia64 From: Jes Sorensen <jes@trained-monkey.org> The new sort_extable and shared search_extable code doesn't work on ia64. I have introduced two new #defines that archs can define to avoid the common code being built. ARCH_HAS_SEARCH_EXTABLE and ARCH_HAS_SORT_EXTABLE. <akpm@osdl.org> [PATCH] new module args for ir-kbd-*.c From: Gerd Knorr <kraxel@bytesex.org> Use module_param() rather than the deprecated MODULE_PARM() in this driver. <torvalds@home.osdl.org> Linux 2.6.2-rc1 <davem@nuts.ninka.net> [SPARC64]: Fix 32-bit execve out_mm error path.

Here's a novel idea, check the CPU has machine check capabilities before we start polling registers. I was wondering why my VIA C3 was starting this. Who knows it may solve some of the random crashes I saw there. <bjorn_helgaas@hp.com> [PATCH] ia64: Kconfig cleanup, part 1 <akpm@osdl.org> [PATCH] ia64: i2c config fix ia64 needs to include i2c by hand <trini@kernel.crashing.org> [PATCH] Elvis^H^H^H^H^HPaul has left the building > Paul Mackerras: > o sort exception tables And as more proof that Paul is leaving us ppc32 folks, *sniff*, the following is needed for PPC32 to compile: <akpm@osdl.org> [NET]: Do not mark dummy_free_one() __exit in dummy.c driver. <vnourval@tcs.hut.fi> [IPV6]: Fix link-local address check in datagram.c <shemminger@osdl.org> [IPV6]: More missing sysctl table sentinels in addrconf.c <krkumar@us.ibm.com> [IPV6]: Explicity set *dst to NULL at top of ip6_dst_lookup(). <chas@cmf.nrl.navy.mil> [ATM]: [horizon] avoid warning about limited range of data type <davem@nuts.ninka.net> [SPARC64]: Add missing sched_balance_exec() to 32-bit compat execve(). <vnourval@tcs.hut.fi> [IPV6]: Add and use new 'strict' parameter to ip6_chk_addr(). RFC 2461 requires that the source address of Neighbor Discovery messages is an address assigned to the sending interface. Duplicate Address Detection should also be interface specific. We don't, for example, want a node to DoS itself just because it has two interfaces on the same link and both happen to listen to the same multicast group. If there is a true duplicate on the link, the interface doing DAD will notice it anyway. The attached patch adds a 'strict' parameter to ip6_chk_addr() and ip6_get_ifaddr() to allow link-local protocols like ND and DAD to do strict address checks even on addresses with greater scope than link-local. <akpm@osdl.org> [PATCH] RAID-6 fixes From: "H. Peter Anvin" <hpa@zytor.com> As expected, when it hit mainline I started getting real bug reports... the attached patch does the following: - Fixes a few x86-64 specific bugs; - Removes MMX and SSE-1 from x86-64 (if we have x86-64 we have SSE-2); - Slightly astracts the integer code to make it easier to add architecture-specific optimizations later (e.g. IA64 once gcc gets better IA64 intrinsics support); - Resurrects the user-space testbench, and makes it not output the known false positive of the D+Q case (D+Q is equivalent to a RAID-5 recovery, so I didn't implement it in the user-space testbench.) <akpm@osdl.org> [PATCH] document RAID-6 support in mdadm-1.5.0 From: "H. Peter Anvin" <hpa@zytor.com> This is purely a doc patch saying RAID-6 support is available in mdadm-1.5.0 and the patch is no longer necessary. <akpm@osdl.org> [PATCH] ppc64: add missing sched_balance_exec() call From: Anton Blanchard <anton@samba.org> We were missing the sched_balance_exec call. Could explain some NUMA scheduling weirdness we were seeing. <akpm@osdl.org> [PATCH] ppc64: include i2c in config ppc64 doesn't use drivers/Kconfig (it should) so it needs to include i2c by hand. <vnourval@tcs.hut.fi> [IPV6]: addrconf_sysctl_forward_strategy() needs to invoke rt6_purge_dflt_routers() too. <torvalds@home.osdl.org> Fix APIC timer initialization. We used to write fields that were marked RESERVED and that are apparently some old stale timer base. Stop doing that. Verified with Mikael Pettersson, and confirmed to fix ACPI boot-time lockups for a few people. <rusty@rustcorp.com.au> [NET]: Simplify net/flow.c per-cpu handling. The cpu handling in net/core/flow.c is complex: it tries to allocate flow cache as each CPU comes up. It might as well allocate them for each possible CPU at boot. <suresh.b.siddha@intel.com> [PATCH] ia64: replace inline assembly in sn2 code <mikpe@user.it.uu.se> [PATCH] non-integrated local APIC LVTT init compatibility Add back the old i82489DX bits to use timer scaling for the old non-integrated APIC setup.

Peter Anvin" <hpa@transmeta.com> Fix for RAID-6 on IA-64, from Bjorn Helgaas, and verified by me. <akpm@osdl.org> [PATCH] ppc32: Fixes to the signal context code From: Benjamin Herrenschmidt <benh@kernel.crashing.org> This patch (which has been in my tree for some time now) does 2 things to the ppc32 signal code: - The new sys_swapcontext() syscall that we added recently (and which is _not_ yet used by glibc, so it's ok to change it slightly at this point, glibc kernel version check will limit us to 2.6.2 or 2.6.3) gets a new context size argument, so we can deal with future context size changes. - When ucontext is get/set/swapped using the above syscall, the TLS (r2) is preserved (it's still saved/restored on signal entry & return though). The equivalent of this patch is already in the ppc64 signal32.c emulation, and it has no effect until glibc is updated to use the new syscall, which should happen soon now, so please apply. <akpm@osdl.org> [PATCH] Fix rq_for_each_bio() macro again From: Rusty Russell <rusty@rustcorp.com.au> Looks like an obvious typo.

It should stream a lot better now; but not all the funky cases are handled yet. - Now "use_dma_chaining" is a module parameter not a #define. It also defaults to false. Some gadget drivers will work fine with this enabled, getting some IRQ reduction and increased I/O parallelism (given deep I/O queues); others won't. - Handle isochronous transfers (from Mark Huang at Broadcom) - Some of the chiprev 0100 workarounds weren't quite right. Neither were buffer allocations on dma-incoherent systems. - Handle bulk endpoint halts better, for file_storage gadget driver. - Handle the hardware device status bits better: * selfpowered by default, clearable with the API; * remote wakeup disabled by default, host must enable it. - Fix a shutdown problem seen in some statically linked configs. Needed to use the new file_storage gadget without disabling DMA. <david-b@pacbell.net> [PATCH] USB gadget: add File-backed Storage Gadget (FSG) (From Alan Stern.) The File-backed Storage Gadget provides support for the USB Mass Storage protocol. It causes a gadget to appear to the host as a USB disk drive, using a regular file or a block device to provide the necessary storage somewhat like the "loop" device. The driver supports up to 8 Logical Units, appearing to the host as multiple disks, each configurable independently for read-write or read-only access. The settings for the Logical Units are available through sysfs attribute files. The driver has a testing version, selectable by a kernel configuration option. The test version includes many additional module parameters, allowing the USB protocol, subclass, vendor, product, and release values to be set. It also has an option to emulate removable media, and the sysfs interface allows the backing files and the read-only settings to be switched on-the-fly. In both versions several logging and debugging levels are available. They provide a nice way of seeing exactly what commands a USB host is sending to the gadget. <david-b@pacbell.net> [PATCH] USB gadget: config/build updates This updates and simplifies the kernel config for the gadget drivers.

One change is that it uses drivers/Kconfig now like i386. This requires a few minor changes in outside Kconfig files which I am sending separately. - Tighten/fix some code in NUMA node discovery - Fix oopses in threaded 32bit coredumps and read correct registers. - Merge with 2.6.2rc1 - Sync arch/x86_64/Kconfig with i386. Uses drivers/Kconfig now. - Remove bcopy export - Fix check for signal stack for 32bit signals - Fix bcopy and exit prototypes for gcc 3.4 - Fix asm contraint in usercopy.c for gcc 3.4 - Use rt_sigreturn, not sigreturn for rt sigreturns. - Pass si_fault address to 32bit - Truncate si_error to 16bit in 32bit emulation to match i386 - Move IA32 flag switching for 32bit executables to flush_thread (code copied from ppc64/sparc64) - Print exception trace for strace too, share code. - Default to 3GB address space for a.out executables - Fix security hole in ptrace. Also fixes some problems with 32bit gdb. - Sync mmap address selection algorithm with mm/mmap.c version - Disable a.out coredumps completely - Fix bug in sigaltstack 32bit emulation. Kylix IDE now works. - Move errata 93/BIOS workaround into fault handler. This should work around USB legacy BIOS bugs too, although not completely (we cannot fix faults injected by SMM into user space 64bit processes) - Quieten some unimplemented 32bit syscall warnings and avoid repeated warnings. - Set LDT segment limit correctly (fixes problems with some modify_ldt user) - Remove obsolete ldt rw lock. - Remove sys32_modify_ldt. The standard sys_modify_ldt is equivalent. - Remove traces of old kgdb support - Merge CFI changes from Jim Houston and some other smaller changes The kernel assembly functions are described with dwarf2 unwind information now, which makes it easier for debuggers to make sense of stack backtraces. The code is only enabled with CONFIG_DEBUG_INFO. Note this implies that when you use CONFIG_DEBUG_INFO you may need an binutils update. - defconfig updated - Readd sleep support code (Pavel Machek) - Drop fusion and flush workarounds from IOMMU code - Add iommu=nofullflush option - Rewrite 32bit emulation for siginfo conversion (Joe Korty) - Allow remapping of scatterlists after unmap. This fixes some problems with the SCSI layer retrying previously mapped sg lists when iommu merging was enabled (it's disabled now by default) - Port HPET rtc device emulation code from i386 <ak@suse.de> [PATCH] Kconfig fixes for x86-64 x86-64 using drivers/Kconfig requires some minor changes.

The problem with changing things in the core is always that you may miss some of the repercussions. In this case the patch will restore the code's original functionality. However the whole thing looks a bit creaky to me. Changing device descriptors and who knows what else without informing usbcore isn't a good idea. What this code _really_ appears to need is some form of usb_device_reenumerate(). Such a function would fit very nicely into the framework I've worked out for the revised usb_device_reset(); maybe I'll add it in there. It would do essentially the same thing as device_reset except for skipping the actual port reset. <khali@linux-fr.org> [PATCH] I2C: Bring lm75 and lm78 in compliance with sysfs naming conventions Here is a patch that brings the lm75 and lm78 drivers in compliance with sysfs naming conventions. The drivers as found in existing 2.6 kernels do not have a digit appended to the temperature-related files names as the sysfs naming conversion recommends (obviously because they each have a single temperature channel). As a result, libsensors won't find the files. It was discussed on the list wether a '1' should be appended in this case, and our conclusion was that it would be better to do so because it helps automatic processing of the sysfs exported files.

Please note that I haven't attempted to reproduce the problem with recent kernels, and that all ARM kernel patches released since then have had this patch in. I'm guessing this will actually be 2.6.1 material since it probably doesn't show for PCI drivers which are part of the kernel tree. If pci_register_driver fails, the register the PCI driver structure will not be registered with the driver model. pci_register_driver returns with negative value, and we then attempt to unregister the driver structure. This leads to an oops in the driver model. The driver model does not return the number of devices it successfully bound the driver to, and neither does pci_register_driver() return this information. Therefore, all of the code below is redundant. (There's a little redundancy left in drivers/pci/pci-driver.c but it is harmless unlike this block.) <eike-hotplug@sf-tec.de> [PATCH] PCI Hotplug: Fixup pcihp_skeleton.c The functions are not named *_skel_*, so it seems useful not to call them with this. <willy@debian.org> [PATCH] PCI Hotplug: Better reporting of PCI frequency / bus mode problems for acpi driver When plugging a 33MHz card into a bus that's running at 66MHz, I'd like to see a better error message than: acpiphp_glue: notify_handler: unknown event type 0x5 for \_SB_.SBA0.PCI4.S2F0 The following patch would give us: Device \_SB_.SBA0.PCI4.S2F0 cannot be configured due to a frequency mismatch which I think is clearer. <colpatch@us.ibm.com> [PATCH] PCI: add pci_bus sysfs class This is needed to show pci bus topology to userspace properly. <willy@debian.org> [PATCH] PCI: add pci_get_slot() function tg3.c has a bug where it can find the wrong 5704 peer on a machine with PCI domains.

This lets the PPC pci hotplug driver initialize single devices, not just entire slots. <kieran@mgpenguin.net> [PATCH] PCI: name length change - Changes gen-devlist.c to truncate long device names rather than reject the database - Changes PCI_NAME_SIZE to 96 (and PCI_NAME_HALF to 43) to allow all current pci.ids names to fit - Modifies gen-devlist.c to truncate at 89 characters rather than 79 - allows for two digit instance numbers to be added to the name as well while staying within the 96 characters allocated. No names in the current pci.ids are any longer than this. - Modifies names.c to no longer limit device name length when displaying both vendor and device name; the truncation is done by gen-devlist.c. <kieran@mgpenguin.net> [PATCH] PCI: pci.ids update - Replaces pci.ids with a snapshot from pciids.sf.net from 14 Jan 2004 <greg@kroah.com> [PATCH] PCI: fix compiler warning in probe.c cause by PPC patch. <nathans@sgi.com> [XFS] Fix a warning from some gcc variants after recent flags botch.

Modified based on comments from Pavel Machek <pavel@suse.cz>, who has acked the updated patch. <rmk@flint.arm.linux.org.uk> [ARM] Eliminate tsk->used_math Remove usage of tsk->used_math on ARM, moving the status to an array of co-processor usage. (ARM can have up to 15 co-processors providing various extra facilities such as SIMD, VFP or FP.) <rmk@flint.arm.linux.org.uk> [ARM] Fix bitops pointer qualifiers. According to x86, the pointers for bitops are supposed to be qualified with volatile. Make ARM bitops reflect this. <rmk@flint.arm.linux.org.uk> [ARM] Add comments for newish functions in cacheflush.h <linux@dominikbrodowski.de> [PATCH] Validate ACPI CPU frequency values This is a simple fix for some of the problems with bad ACPI frequency values: Abort if the frequency field in _PSS is zero, as we're having a completely broken ACPI table then. A more complete overhaul of the acpi-cpufreq driver (where the cause of the problem lies) is in the latest acpi-test tree, but that's definitely something to be delayed for 2.6.3 -- and the same is true for the yet-to-be-written do_div64 conversion. <hunold@convergence.de> [PATCH] dvb subsystem and saa7146 v4l fixes This fixes some issues in the dvb subsystem and some nasty things in the v4l saa7146 driver. [DVB] - dvb-core: aquire -> acquire spelling fix - nxt600 frontend: don't send zero-byte messages when probing the PLL type - Kconfig: add a note that says that the CI of the budget-CI card is not actually supported by the budget-CI driver - ttusb-dec: Check for presence of crc32 function. Make unknown types of packet less likely to cause packet loss. [V4L] - saa7146: use kernel mint_t()/max_t() instead of homebrewn stuff - saa7146: disable video clipping before capturing for sure to prevent black pictures - saa7146: make sure to disable the right video dma upon device close - saa7146: don't free resources if disabling an already disabled video overlay <rmk@flint.arm.linux.org.uk> [ARM] Remove FP work-arounds. We used to have code to allow binaries linked against glibc to run, when glibc itself contained some FP instructions (for PCS stack frames for functions like printf and scanf) thereby allowing FP emulators like nwfpe to be built as modules. This has proved to be unreliable with later compilers, so support for this was dropped a while ago. Since no one complained, we can finally remove the dead code. (NB. a klibc based module-init-tools shouldn't suffer from this problem.) <torvalds@home.osdl.org> Fix sha256 padding block initializer to be static. Jakub points out that having an automatic array is not only bad for performance (and stack usage), gcc has also historically had lots of bugs here, and gcc-3.2.3 seems to miscompile it otherwise. <davem@nuts.davemloft.net> [SPARC64]: Fix wakeup races in power.c, with help from Andrew Morton. <marcelo.tosatti@cyclades.com> [PATCH] PC300 update This forward ports a few important fixes from the 2.4 driver. This changes have been well tested. Changelog: - Update maintainer email address - Mark pci_device_id list with __devinitdata. - Set correct protocol type on packet receive (this caused the kernel to drop all packets received) - Add #ifdef DEBUG around debug printk() - ioctl: Add missing size checks before copying data from userspace. <torvalds@home.osdl.org> Linux 2.6.2-rc3 <mlindner@syskonnect.de> [PATCH] sk98lin: Reset Xmac when stopping the port * Clear the Xmac fifo before stopping the port <akpm@osdl.org> [PATCH] ppc32: watchdog definition fixes From: Tom Rini <trini@kernel.crashing.org> Correct the defines for MC146818 RTCs, reg c is interrupts, reg d is not watchdog (it's valid time & nvram). <akpm@osdl.org> [PATCH] ppc64: add missing include guards, from Nathan Lynch From: Anton Blanchard <anton@samba.org> add missing include guards, from Nathan Lynch <akpm@osdl.org> [PATCH] ppc64: lparcfg_write From: Anton Blanchard <anton@samba.org> Add lparcfg_write() for changing SPLPAR system parameters <akpm@osdl.org> [PATCH] ppc64: fixes for compile with CONFIG_PROC_DEVICETREE=n, from Nathan Lynch From: Anton Blanchard <anton@samba.org> - nop out proc_device_tree_add_node if CONFIG_PROC_DEVICETREE=n - stubs for procfs-related functions when CONFIG_PROC_DEVICETREE=n <akpm@osdl.org> [PATCH] ppc64: missing set_fs(KERNEL_DS) in ppc32_timer_create, from Marcus Meissner From: Anton Blanchard <anton@samba.org> Small obvious fix to ppc32_timer_create. Since sys_timer_create access structures we pass on the stack, we need set_fs(KERNEL_DS). <akpm@osdl.org> [PATCH] ppc64: defconfig update From: Anton Blanchard <anton@samba.org> <akpm@osdl.org> [PATCH] ppc64: Use preferred_console to select a reasonable default console From: Anton Blanchard <anton@samba.org> Lets make a decent attempt to find out where your console is. The new preferred_console stuff is pretty nice. <akpm@osdl.org> [PATCH] ppc64: add/remove config.h From: Anton Blanchard <anton@samba.org> <akpm@osdl.org> [PATCH] ppc64: export memchr and csum_partial From: Anton Blanchard <anton@samba.org> <akpm@osdl.org> [PATCH] ppc64: fix && vs & bugs in lparcfg, from Julie DeWandel From: Anton Blanchard <anton@samba.org> <akpm@osdl.org> [PATCH] ppc64: SLB rewrite From: Anton Blanchard <anton@samba.org> The current SLB handling code has a number of problems: - We loop trying to find an empty SLB entry before deciding to cast one out. On large working sets this really hurts since the SLB is always full and we end up looping through all 64 entries unnecessarily. - During castout we currently invalidate the entry we are replacing. This is to avoid a nasty race where the entry is in the ERAT but not the SLB and another cpu does a tlbie that removes the ERAT at a critical point. If this race is fixed the SLB can be removed. - The SLB prefault code doesnt work properly The following patch addresses all the above concerns and adds some more optimisations: - feature nop out some segment table only code - slb invalidate the kernel segment on context switch (avoids us having to slb invalidate at each cast out) - optimise flush on context switch, the lazy tlb stuff avoids it being called when going from userspace to kernel thread, but it gets called when going to kernel thread to userspace. In many cases we are returning to the same userspace task, we now check for this and avoid the flush - use the optimised POWER4 mtcrf where possible <akpm@osdl.org> [PATCH] ppc64: use CONFIG_MAGIC_SYSRQ around xmon sysrq code From: Anton Blanchard <anton@samba.org> <akpm@osdl.org> [PATCH] Trivial cleanups to hugepage support From: David Gibson <david@gibson.dropbear.id.au> These are some trivial cleanups to the hugepage ppc64 support <akpm@osdl.org> [PATCH] s390: general update. From: Martin Schwidefsky <schwidefsky@de.ibm.com> s390 general update: - Add archhelp for "make image". - 32-bit execve fix. - Export some symbols: sys_ioctl, put_files_struct & ccw_device_work. - Minor cleanups in arch/s390/mm/init.c & drivers/s390/net/ctctty.c. <akpm@osdl.org> [PATCH] s390: inline assembly constraints. From: Martin Schwidefsky <schwidefsky@de.ibm.com> s390 inline assembly bug-fixes: - Add memory barriers to spinlocks, atomic variable functions and to test_and_{set,clear,change}_bit. - Add "=m" and "m" contraints to tell gcc that the content of a variable is in fact used. - Replace "+m" constraints by "=m" on the output and "m" on the input list. - Use c-implemtation for ffz and __ffs. - Use generic c-implemtation for ffs and fls. <akpm@osdl.org> [PATCH] s390: sclp bug fixes. From: Martin Schwidefsky <schwidefsky@de.ibm.com> SCLP console/tty fixes: - Fix incorrect state change of SCLP_RUNNING flag in interrupt handler - Suppress emission of empty buffers to prevent stack overflow - Fix off by one error in sclp_write (used to return # of chars written + 1) - Prevent sclp_tty_write_string from waiting in interrupt (during flush) - Fix deadlock after TIOCSCLPSNL ioctl - Fix sclp_tty_chars_in_buffer calculation <akpm@osdl.org> [PATCH] RAID-6: x86-64 crash workaround From: "H. Peter Anvin" <hpa@zytor.com> Apparently, on x86-64, the stack isn't always aligned properly (16 bytes) in the kernel at the moment. This causes the RAID-6 code to crash the system. This patch is a workaround for that; the right thing is to muck with the assembly entrypoints to enforce proper stack alignment. However, that's not anything I feel comfortable doing in an evening, especially since I don't have a machine on which I can test the resulting kernels. <torvalds@home.osdl.org> Upgrade x86 defconfig to something less ancient. <akpm@osdl.org> [PATCH] ppc32: MBX MAC address fix From Tom Rini <trini@kernel.crashing.org> On the MBX the kernel made an assumption about where the MAC address would be in the VPD (Vital Product Data). However, the documentation for the firmware (EPPC-Bug) describes the format of the VPD and makes no guarrantees about the location of any VPD record. It does however describe the format of each record type and the MAC address record will be of type '08' and of size 6. This changes the code so that instead of assuming a position, it searches for the record, which I assume is also what EPPC-Bug does. <torvalds@home.osdl.org> Make EHCI have a 20ms power-on to power-good timeout. This should fix some picky USB devices. <bcollins@debian.org> IEEE1394(r1112): Adds a "ieee1394_guid" attribute to the scsi device for sbp2. <bcollins@debian.org> IEEE1394(r1116): Make sure to unregister addr space when a driver is removed. <akpm@osdl.org> [PATCH] fix the build for NR_CPUS > 4*BITS_PER_LONG You can't just cast cpumasks. It doesn't compile if NR_CPUS is greater than 4 * BITS_PER_LONG. <B.Zolnierkiewicz@elka.pw.edu.pl> [PATCH] fix issues with loading PCI IDE drivers as modules From: Davin McCall <davmac@ozonline.com.au> Set hwif->chipset to ide_forced if it was forced by kernel parameters. Set hwif->chipset to ide_generic for hwifs controlled by generic IDE code, so they wont be taken by setup_pci.c:ide_match_hwif(). Patch also fixes /proc/ide/ideX/model to report "generic" instead of "(none)" for default hwifs. This has been in -mm since 2.6.1-mm1. <davem@nuts.davemloft.net> [COMPAT]: Fix TUNSETIFF ioctl compat, it takes an ifreq ptr not an int. Thanks to Eric Brower for spotting this. <B.Zolnierkiewicz@elka.pw.edu.pl> [PATCH] fix/improve modular IDE This has been in -mm since 2.6.1-mm5 - IDE can be used as module again (compiles and works), this fixes bugzilla bugs #576 and #1700 - separate module for probing is no longer required - generic/default host driver is available as ide_generic module This contains the build fixes by Adrian Bunk and Andrew Morton. <wesolows@foobazco.org> [SPARC32]: Align pkmap properly. Align the pkmap area on a 4MB region so that a single large pagetable can be used. Fixes random killing of processes which used high memory. <wesolows@foobazco.org> [SPARC32]: Copy full soft PMD in vmalloc fault handler. sparc_do_fault assumes that pmd_val(*pmd) = pmd_val(*pmd_k) will duplicate a PMD entry. With large soft-PMDs this doesn't work. <wesolows@foobazco.org> [SPARC32]: Kill spurious newline in dmesg output <grundler@parisc-linux.org> [TG3]: Only fetch NVRAM_CMD reg if TG3_FLAG_NVRAM. <len.brown@intel.com> [ACPI] proposed fix for AML parameter passing from Bob Moore http://bugzilla.kernel.org/show_bug.cgi?id=1766 <davem@nuts.davemloft.net> [TG3]: Bump version and reldate. <kadlec@blackhole.kfki.hu> [NETFILTER]: Fix NAT leak with fragmented packets, missing conntrack put in ip_copy_metadata(). <torvalds@home.osdl.org> Warn loudly if somebody passes a negative value as the size to "vsnprintf()". That's a pretty clear case of overflow. <torvalds@home.osdl.org> Linux 2.6.2 aka "Feisty Dunnart" See http://www.cse.unsw.edu.au/~gernot/persona/hobbies/dunnart.html for more information about Dunnarts, in case you've never heard of them before.
