[netdrvr epic100] minor cleanups
- extra pci_disable_device() to balance invocation of pci_enable_device()
in epic_init_one() (-> error path + epic_remove_one());
- lazy return status in epic_init_one(), tsss...;
- memory dedicated to Rx descriptors was not freed after failure of
register_netdev() in epic_init_one();
- use of epic_pause() in epic_close() offers a small window for a late
interruption just before the final free_irq(). Let's close the window to
avoid two epic_rx() threads racing with each other.

[netdrvr epic100] napi 1/3 - just shuffle some code around
Isolate the classical TX part of epic_interrupt. Innocent code shuffling.
<romieu@fr.zoreil.com>
[netdrvr epic100] napi 2/3 - receive path
<romieu@fr.zoreil.com>
[netdrvr epic100] napi 3/3 - transmit path
<romieu@fr.zoreil.com>
[netdrvr epic100] napi fixes
Multiple invocation of __netif_rx_schedule() in epic_interrupt() while
epic_poll loops over __netif_rx_complete() leads to serious device
refcount leak.

[PATCH] epic100: spin_unlock_irqrestore avoidance
This patch avoids to duplicate a spin_unlock:
- it is mostly an artifact due to wild goto;
- it makes the generated code smaller.
<romieu@fr.zoreil.com>
[PATCH] epic100: code removal in irq handler
The loop in the irq handler is not needed any more as the high frequency
events have been deferred due to napi usage.

[MMC] Add MMC core support
This patch adds core support to the Linux kernel for driving MMC
interfaces found on embedded devices, such as found in the Intel
PXA and ARM MMCI primecell. This patch does _not_ add support
for SD or SDIO cards.
It is vaguely based upon the handhelds.org MMC code, but the bulk
of the core has been rewritten from scratch.
<rmk@flint.arm.linux.org.uk>
[MMC] Add Kconfig/Makefile changes for MMC support.
Since this is currently ARM-only, I've dropped the drivers/Kconfig
change for the time being.
<rmk@flint.arm.linux.org.uk>
[MMC] Add ARM MMCI Primecell driver.
This patch adds initial support for the ARM MMCI Primecell - one of
the drivers for a MMC interface.

[MMC] Add PXA MMC interface support.
This patch adds support for the Intel PXA MCI interface.

[ACPI] ACPICA 20040402 from Bob Moore
Fixed an interpreter problem where an indirect store through an
ArgX parameter was incorrectly applying the "implicit conversion
rules" during the store. From the ACPI specification: "If the
target is a method local or argument (LocalX or ArgX), no
conversion is performed and the result is stored directly to the
target". The new behavior is to disable implicit conversion
during ALL stores to an ArgX.
Changed the behavior of the _PRW method scan to ignore any and
all errors returned by a given _PRW. This prevents the scan from
aborting from the failure of any single _PRW.
Moved the runtime configuration parameters from the global init
procedure to static variables in acglobal.h. This will allow the
host to override the default values easily.
<len.brown@intel.com>
[ACPI] ACPICA 20040427 from Bob Moore
Completed a major overhaul of the GPE handling within ACPI CA.
There are now three types of GPEs:
wake-only; runtime-only; combination wake/run.
The only GPEs allowed to be combination wake/run are for
button-style devices such as a control-method power button,
control-method sleep button, or a notebook lid switch.
GPEs that have an _Lxx or _Exx method and are not referenced
by any _PRW methods are marked for "runtime" and hardware enabled.
Any GPE that is referenced by a _PRW method is marked for "wake"
(and disabled at runtime). However, at sleep time, only those
GPEs that have been specifically enabled for wake via the
acpi_enable_gpe() interface will actually be hardware enabled.
A new external interface has been added, acpi_set_gpe_type()
that is meant to be used by device drivers to force a GPE
to a particular type. It will be especially useful for the
drivers for the button devices mentioned above.
Completed restructuring of the ACPI CA initialization sequence
so that default operation region handlers are installed
before GPEs are initialized and the _PRW methods are executed.
This will prevent errors when the _PRW methods attempt to
access system memory or I/O space.
GPE enable/disable no longer reads the GPE enable register.
We now keep the enable info for runtime and wake separate
and in the GPE_EVENT_INFO. We thus no longer depend on
the hardware to maintain these bits.
Always clear the wake status and fixed/GPE status bits
before sleep, even for state S5.
Improved the AML debugger output for displaying the
GPE blocks and their current status.
Added new strings for the _OSI method, of the form
"Windows 2001 SPx" where x = 0,1,2,3,4.
Fixed a problem where the physical address was incorrectly
calculated when the Load() operator was used to directly
load from an Operation Region (vs. loading from a Field object.)
Also added check for minimum table length for this case.
Fix for multiple mutex acquisition. Restore original thread
SyncLevel on mutex release.
Added ACPI_VALID_SXDS flag to the acpi_get_object_info interface
for consistency with the other fields returned.
Shrunk the ACPI_GPE_EVENT_INFO structure by 40%.
There is one such structure for each GPE in the system,
so the size of this structure is important.
CPU stack requirement reduction:
Cleaned up the method execution and object evaluation paths
so that now a parameter structure is passed, instead of copying
the various method parameters over and over again.
In evregion.c:
Correctly exit and reenter the interpreter region if and only
if dispatching an operation region request to a user-installed
handler. Do not exit/reenter when dispatching to a default
handler (e.g., default system memory or I/O handlers)

[PATCH] r8169: napi support
Napi for r8169 (Jon D Mason <jonmason@us.ibm.com>).
Both Tx and Rx processing are moved to the ->poll() function.
<romieu@fr.zoreil.com>
[PATCH] r8169: cosmetic renaming of a register
RxUnderrun status bit renamed to LinkChg (identical to the 8139cp driver).
<romieu@fr.zoreil.com>
[PATCH] r8169: janitoring
Spring cleanup
- unsigned int (u32) should be slightly faster on ppc64 (Jon D Mason);
- misc minor de-uglyfication.
<romieu@fr.zoreil.com>
[PATCH] r8169: ethtool .set_settings
ethtool set_settings support (Andy Lutomirski <luto@myrealbox.com>).
The initial code has been modified so that the settings of parameters
for TBI and normal mode do not step on each others shoes.
<romieu@fr.zoreil.com>
[PATCH] r8169: ethtool .get_{settings/link}
- ethtool get_settings() for r8169 (Andy Lutomirski <luto@myrealbox.com>);
- rtl8169_ethtool_ops.get_drvinfo() is set as well;
- added some bits to handle the TBI status.
The locking does not need to be specially clever.
<rmk@flint.arm.linux.org.uk>
[MMC] Fix PXA MMC interface issues.
- Wait for STAT_CLK_EN to clear rather than waiting for the CLK_IS_OFF
interrupt when stopping the MMC clock.
- Always return the number of data blocks transferred no matter what.
- Set the device driver data correctly.
<romieu@fr.zoreil.com>
[PATCH] r8169: link handling and phy reset rework
Link handling changes (Andy Lutomirski <luto@myrealbox.com>):
- removed rtl8169_hw_phy_reset() and its busy loop;
- RTL8169_PHY_TIMEOUT is x10 to account for the removal of the
phy_link_down_cnt loop in rtl8169_phy_timer();
- added spinlocking in timer context for rtl8169_phy_timer to avoid
messing with the {set/get}_settings commands issued via ethtool;
- more TBI stuff.
This patch differs from the former version on the following points:
- the LinkChg irq does not enable the phy timer when the link goes
down any more;
- the phy timer is not enabled in rtl8169_set_speed();
- removal of the initial renegotiation hack.
<romieu@fr.zoreil.com>
[PATCH] r8169: initial link setup rework
Use rtl8169_set_speed() for link setup in rtl8169_init_one():
- the code which handles the option checking is isolated;
- display (once) a notice message about the deprecated interface;
- rtl8169_open() enables the phy timer if the link is not up;
- rtl8169_set_speed() checks that the netdevice is actually ready
in order to activate the timer.
<romieu@fr.zoreil.com>
[PATCH] r8169: gcc bug workaround
Add a temporary variable to workaround gcc 2.95.3 bug.
<romieu@fr.zoreil.com>
[PATCH] r8169: tx lock removal
spinlock removal crusade.
The patch rephrases the spinlock_irq() in rtl8169_start_xmit() and its
companion in the Tx irq handling patch in terms of ordered operations.
<scott.feldman@intel.com>
[PATCH] e100: use NAPI mode all the time
I see no reason to keep the non-NAPI option for e100. This patch removes
the CONFIG_E100_NAPI option and puts the driver in NAPI mode all the time.
Matches the way tg3 works.
Unless someone has a really good reason to keep the non-NAPI mode, this
should go in for 2.6.7.

[PATCH] via-velocity: PCI ID move

are not included in Jeff's -netdev patches).
PCI ID moved from the driver to the kernel database. A change for the
pci.ids file project at souceforge has been submitted as well.
<romieu@fr.zoreil.com>
[PATCH] via-velocity: uniformize use of OWNED_BY_NIC
Introduce velocity_give_rx_desc() to uniformize the use of OWNED_BY_NIC
through the driver.
<romieu@fr.zoreil.com>
[PATCH] via-velocity: velocity_receive_frame diets
Weight loss in velocity_receive_frame():
- isolate the ip header alignment tsk from velocity_receive_frame();
- following p.30 of the datasheet, rdesc0.len includes the CRC length:
the amount of data copied during the ip alignment can be shortened.
<akpm@osdl.org>
[PATCH] fix via-velocity oopses
- Don't register the inet_addr notifier if the hardware is absent. It
oopses when other interfaces are being upped.
- Mark velocity_remove1() as __devexit_p in the pci_driver table.
- c99ification.

[PATCH] Restructure reset code
Restructure code to make it easier to maintain.

rhine_chip_reset: chip reset + what used to be wait_for_reset
rhine_reload_eeprom: reload eeprom, re-enable MMIO, disable EEPROM-controlled
WOL

[PATCH] Rewrite PHY detection
Instead of probing, set phy_id to 1 for Rhine III and read phy_id from
EEPROM-controlled register for Rhine I/II.
Remove code for handling anything other than 1 MII PHY. If it wasn't
unnecessary code to begin with, it would need to be fixed because it
wouldn't work.
Use mii_if_info.phy_id as the only container of phy_id. Not particulary
happy about those names (phy_id vs. MII_PHYSIDx), but being consequent
about it mitigates confusion.

[PATCH] Remove options, full_duplex parameters
Nobody complained although media locking parameters were broken
forever. They were sort of fixed recently, but the code is still in a
bad shape.
More seriously, the options/full_duplex stuff has fundamental design
problems that have been discussed in-depth on the list (e.g. effect of
hotplugging, nameif, suspend/resume).
For those needing media locking with Linux 2.6+ via-rhine, ethtool(8)
is the replacement.

[PATCH] Fix Tx engine race for good
It finally dawned on me how to eliminate the race I've been narrowing
down with earlier patches: Instead of writing the command registers as
one word, write them one at a time (as bytes). The race was for settings
bits in ChipCmd and ChipCmd1 (0x09) against the chip clearing CmdTxOn
which is in ChipCmd.
In addition to writing single bytes, the fix requires a switch from
using bit 5 in ChipCmd0 to bit 5 in ChipCmd1 (which is equivalent)
to signal Tx demand.
Also, don't restart Rx engine "pre-emptively" in rhine_rx, that's a
sure way to race with the chip.
Introduce RHINE_WAIT_FOR, a macro for small busy loops with primitive
completion checking.

[PATCH] Media mode rewrite

[PATCH] via-velocity: Rx buffers allocation rework
Rework of the Rx buffers allocation:
- Rx irq handler (velocity_rx_srv): defer the Rx buffer allocation until
the packet processing loop is done;
- a separate index related to the Rx descriptor ("rd_dirty") is introduced
to distinguish the first Rx descriptor whose buffer has to be refilled.
This way the driver does not need to confuse this descriptor with the
most recently netif()ed one. Rationale: batch + rx_copybreak;
- dirty/empty Rx descriptors are identified through the whole driver
via an adequate NULL pointer in the velocity_rd_info[] array (see
velocity_rx_refill() and velocity_receive_frame());
- Rx descriptors need to be grouped by a multiple of 4 before they can
be handed back to the asic (hardware constraint). This task is moved
from the Rx processing loop to the Rx refill function;
- factorization of code in velocity_init_rd_ring().
<romieu@fr.zoreil.com>
[PATCH] via-velocity: Rx copybreak
Handle copybreak.
- velocity_rx_refill() is modified to allow the processing of a Rx desc
ring wherein the empty skb slots are not necessarily contiguous. Given
the preceeding changes, rx_copybreak should not need anything else;
- the driver does not rely on rd_info->skb_dma set to NULL any more;
- pci_dma_sync_single_for_{cpu/device} changes as a bonus;
- more function documentation.
Some inspiration borrowed from similar r8169 code.
<romieu@fr.zoreil.com>
[PATCH] via-velocity: ordering of Rx descriptors operations
Force strict ordering of operations on Rx descriptors to avoid any issue
related to inline optimization.

[ACPI] ACPICA 20040514 from Bob Moore
Fixed a problem where hardware GPE enable bits sometimes
not set properly during and after GPE method execution.
Result of ACPICA 20040427 changes.
Removed extra "clear all GPEs" when sleeping/waking.
Removed acpi_ht_enable_gpe and acpi_hw_disable_gpe, replaced
by the single acpi_hw_write_gpe_enable_reg. Changed a couple
of calls to the functions above to the new acpi_ev* calls
as appropriate.
ACPI_OS_NAME was removed from the OS-specific headers.
The default name is now "Microsoft Windows NT" for maximum
compatibility. However this can be changed by modifying
the acconfig.h file. Fixes EHCI probe issue:
http://bugme.osdl.org/show_bug.cgi?id=1762
Allow a single invocation of acpi_install_notify_handler
for a handler that traps both types of notifies (System,
Device). Use ACPI_ALL_NOTIFY flag.
Run _INI methods on ThermalZone objects. This is against
the ACPI specification, but there is apparently ASL code
in the field that has these _INI methods, and apparently
"other" AML interpreters execute them.
Performed a full 16/32/64 bit lint that resulted in some
small changes.

[ACPI] ACPICA 20040527 from Bob Moore
Completed a new design and implementation for EBDA
(Extended BIOS Data Area) support in the RSDP scan code.
The original code improperly scanned for the EBDA by simply
scanning from memory location 0 to 0x400. The correct
method is to first obtain the EBDA pointer from within
the BIOS data area, then scan 1K of memory starting at the
EBDA pointer. There appear to be few if any machines that
place the RSDP in the EBDA, however.

[PATCH] PCI Hotplug: acpiphp extension for 2.6.7, part 1
This patch adds the ability to register callback functions with

status. The reason this is needed is because there is not set
ACPI standard for how this is done so each hardware platform may
implement it differently. To keep hardware specific code out of
acpiphp, we allow other modules to register their code with it.

the callbacks and sets up a handler to read ACPI events and
forward them on to /proc/acpi/event. It also exports an ACPI
table that shows current hotplug status to userland.

<len.brown@intel.com>
[ACPI] ACPICA 20040715 from Bob Moore
Restructured the internal HW GPE interfaces to pass/track
the current state of interrupts (enabled/disabled) in
order to avoid possible deadlock and increase flexibility
of the interfaces.
Implemented a "lexicographical compare" for String and
Buffer objects within the logical operators -- LGreater,
LLess, LGreaterEqual, and LLessEqual -- as per further
clarification to the ACPI specification. Behavior is
similar to C library "strcmp".
Completed a major reduction in CPU stack use for the
acpi_get_firmware_table external function. In the 32-bit
non-debug case, the stack use has been reduced from 168
bytes to 32 bytes.
Deployed a new run-time configuration flag,
acpi_gbl_enable_interpeter_slack, whose purpose is to allow
the AML interpreter to forgive certain bad AML constructs.
Default setting is FALSE.
Implemented the first use of acpi_gbl_enable_interpeter_slack
in the Field IO support code. If enabled, it allows field
access to go beyond the end of a region definition if the
field is within the region length rounded up to the next
access width boundary (a common coding error.)
Renamed OSD_HANDLER to acpi_osd_handler, and
OSD_EXECUTION_CALLBACK to acpi_osd_exec_callback for
consistency with other ACPI symbols. Also, these symbols
are lowercased by the latest version of the acpisrc tool.
The prototypes for the PCI interfaces in acpiosxf.h
have been updated to rename "register" to simply "reg"
to prevent certain compilers from complaining.

[PATCH] USB: Make removable-LUN support a non-test option in the g_file_storage driver
This patch follows the suggestions sent by Todd Fischer and Diego Dompe
for making removable-LUN support part of the normal non-testing version of
the g_file_storage driver. It also moves LUN device registration to the
correct place and eliminates a code path that stalls the bulk-out pipe in
a racy way.
There are also some smaller changes: update some comments, add initial
debugging support for USB suspend/resume, and miscellaneous code cleanups.
Last but not least, the driver has been sufficiently stable for
sufficiently long that it's fair to remove the "(DEVELOPMENT)" warning in
Kconfig.

[PATCH] USB: add CONFIG_USB_SUSPEND
This is the core of the USB_SUSPEND functionality. Please merge.
This adds an experimental CONFIG_USB_SUSPEND option, which supports the
USB "suspend" state. Linux-USB hosts have previously ignored that state.
- New driver API calls, usb_suspend_device() and its
sibling usb_resume_device().
- Access to those calls through sysfs, such as
echo -n 2 > power/state
echo -n 0 > power/state
That can be used to reduce the power consumption of any given USB device,
then re-activate it later. Eventually, most USB device drivers should
probably suspend idle USB devices.
One problem with this patch: USB drivers without suspend() callbacks
may badly misbehave. Right now only hub drivers know suspend(). If the
driver core didn't self-deadlock when we try it, unbinding those drivers
from those devices (then re-enumerating on resume) would be perfect...
the current compromise is just to emit a warning message.
In conjunction with host controller driver support (already merged for
OHCI and EHCI), PCI host controllers will issue the PME# wakeup signal
when a USB keyboard starts remote wakeup signaling. (But the keyboard
wasn't usable later, since HID doesn't try to suspend.)
I understand some ACPI patches are circulating, and maybe already in
the MM tree, to make a suspended system wake up given PME# signaling.
It'd be great if someone made that work transparently with USB, but
for now I'm told it'll need some sysfs setup first.

[CPUFREQ] speedstep-ich SMT support.

[CPUFREQ] fix HT oops on speedstep-ich system
Bugfix for #3012 @ http://bugme.osdl.org/show_bug.cgi?id=3012
The speedstep-ich driver only registers for CPU0 (which is a sane thing to
do). However, cpufreq_notify_transition() currently assumes the CPU
specified in the freqs.cpu parameter has actually been registered with the
CPUfreq core. This is obviously not the case for HT speedstep-ich CPUs,
causing an OOPS. The long-term solution will be to merge the "cpufreq

[PATCH] USB Storage: fix Genesys Logic based on info from vendor
In theory, this is the fix we need to make Genesys Logic devices work.
This patch started life as as343, which was created based on some
information which a user finally coaxed out of Genesys Logic. Limited
end-user testing gives good results.
As we expected, it's a bug in their device. This is really a workaround
for what is almost certainly a timing problem. Apparently, the 'popular'
OSes don't push the device as hard as Linux does.
Although it is likely that this workaround is not needed for all Genesys
devices, Genesys was unable/unwilling to provide us with the explicit list
of VID/PIDs which required this -- thus we apply it to all Genesys devices.
We have lots of good reports with max_sectors set to 128 with these
devices, but the official recommendation is to set that to 64. End-users
can experiment with higher values (for higher performance) via the runtime
sysfs interface to that parameter.
I would like to give special thanks to the users who hounded Genesys into
giving up this information, and to Alan Stern for not giving up on this
vendor long after I had.

basically, the goal is to be more robust against devices that

[ACPI] restore PCI Interrupt Link Devices upon resume
* register as as a sys_device so that we can get resume callbacks and restore
interrupt routing state.
* add acpi_pci_link_resume(), which will be called when resuming from a suspend
state that needs IRQ routing to be restored. This fixes issues reported on
the mailing lists, e.g.:
http://marc.theaimsgroup.com/?l=acpi4linux&m=10914299...
* rename setonboot --> initialized
* change to test acpi_noirq in init
We want to initialize everything on S3 resume in case the BIOS points an
interrupt link somewhere we didn't expect. (Doing so avoids "missing interrupt"
or "irq x: nobody cared" problems.) According to Len, past experience has shown
that it's a good idea to initialize only devices that exist or were explicitly
asked for, so we try to initialize only the IRQ's that were previously
initialized at some point before suspend, by checking the "initialized" flag.
This corresponds to links that have PCI devices attached. Everything else, we
leave alone. Assuming the BIOS does the same thing on resume that it did on
boot, this will leave all the unused links in the same state that they were on
boot.
We are registered as a sysdev in order to do this work fairly early during
resume, before devices are resumed; some devices may not call
pci_device_enable.
Previous "setonboot once" behavior is left in place, to be conservative.

[PATCH] I2C: algorithm and bus driver for PCA9564
Attached is a driver for the PCA9564 "Parallel to I2C" chip, it is
similar in principle to the PCF8584 which is supported by the
i2c-algo-pcf and i2c-elektor code, however it's not code compatible in
any way: http://www.semiconductors.philips.com/pip/PCA9564PW.html
The patch contains the PCA algorithm driver and a bus driver for an ISA
card. It only supports master send and receive but I'm not sure that the
Linux i2c stack supports client side operation anyhow, and I have no
hardware to test on.
It was tested on a PC104 card containing the PCA chip and an Atmel TPM
device and also on a separate PC104 card with a DS1307 RTC hotwired onto
it for testing purposes.
The driver is against a 2.6 BK tree pulled on Friday. I also have a
fairly trivial 2.4 backport if that is of interest.

[PATCH] USB: add <linux/usb_otg.h>
Hardware implementing USB-OTG needs to use an OTG controller and/or
transceiver driver to switch the Mini-AB connector between the host
and peripheral side controller drivers (and the USB device role
supported by that driver).
This patch adds a simple "otg_transceiver" interface that can abstract
implementation details for that port, as needed for some upcoming patches:
- Neither host nor peripheral controller drivers need to know about
how the OTG controller is implemented. Example: is the transceiver
internal? If not, which external chip?
- The OTG controller doesn't need to know if the Host Controller
is OHCI, EHCI, or something custom ... all it knows is that the
HCD looks like a "usb_bus".
- In the same way, the peripheral controller is just a "usb_gadget".
One implementation of this will be posted soon; the interface is by
no means cast in stone, other implementations may need to morph this
interface a bit.

kbuild: Check for undefined symbols in vmlinux
At least one bin-utils version for ARM is know to ignore undefined
symbols when performing the final link of vmlinux.
Add an explicit check for undefined symbols to catch this.
The check is made in combination with generating the System.map file
and the actual algorithm is moved to a small shell script - mksysmap.
External symbols with three leading underscores are ignored - sparc
uses them for the BTFIXUP logic.

kbuild: Use LINUXINCLUDE to specify include/ directory
Peter Chubb <peterc@gelato.unsw.edu.au> reported that building i386
on a non-i386 platform failed, because gcc could not locate boot.h.
Root cause was the extra include2 directory used when using O=
to specify the output directory.
Added LINUXINCLUDE as a portable way to specify the include/
directory, and changed the two users.
This avoids hardcoding 'include2' in non-kbuild core files.

kbuild: Use POSIX headers for ntoh functions
From: Benno <benjl@cse.unsw.edu.au>
When compiling Linux on Mac OSX I had trouble with scripts/sumversion.c.
It includes <netinet/in.h> to obtain to definitions of htonl and ntohl.
On Mac OSX these are found in <arpa/inet.h>. After checking the POSIX
specification it appears that this is the correct place to get
the definitons for these functions.
(http://www.opengroup.org/onlinepubs/009695399/functions/h...)
Using this header also appears to work on Linux (at least with
Glibc-2.3.2).
It seems clearer to me to go with the POSIX standard than implementing
#if __APPLE__ style macros, but if such an approach is preferred I can
supply patches for that instead.

kbuild: __crc_* symbols in System.map
David S. Miller <davem@redhat.com> wrote:
Shouldn't we be grepping __crc_ symbols out of the System.map file?
For one thing, these can confuse readprofile. It's algorithm is
to start at _stext, then stop when it sees a line in the System.map
which is not text (mode is one of 'T' 't' 'W' or 'w')
It will exit early if there are some intermixed __crc_* things in
there (since they are are mode 'A').
For example, in my current sparc64 kernel I have this:
00000000004cef80 t do_split
00000000004cf2a0 t add_dirent_to_buf
00000000004cf5a7 A __crc_init_special_inode
00000000004cf640 t make_indexed_dir
00000000004cf900 t ext3_add_entry
So no symbols after add_dirent_to_buf will be shown in the profiling
output of readprofile.
Implementation ported to mksysmap by Sam.

- Print "SYSMAP System.map" during build
- Sort symbols in System.map

kbuild: Bogus "has no CRC" in external module builds
From: Pavel Roskin <proski@gnu.org>
The recent fixes for the external module build have fixed the major
breakage, but they left one annoyance unfixed. If CONFIG_MODVERSIONS is
disabled, a warning is printed for every exported symbol that is has no
CRC. For instance, I see this when compiling the standalone Orinoco
driver on Linux 2.6.6-rc3:
*** Warning: "__orinoco_down" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
*** Warning: "hermes_struct_init" [/usr/local/src/orinoco/spectrum_cs.ko]
has no CRC!
*** Warning: "free_orinocodev" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
[further warnings skipped]
I have found that the "-i" option for modpost is used for external builds,
whereas the internal modules use "-o". The "-i" option causes read_dump()
in modpost.c to be called. This function sets "modversions" variable
under some conditions that I don't understand. The comment before the
modversions declarations says: "Are we using CONFIG_MODVERSIONS?"
Apparently modpost fails to answer this question. I think it's better to
use an explicit option rather than a kludge.
The attached patch adds a new option "-m" that is specified if and only if
CONFIG_MODVERSIONS is enabled. The patch has been successfully tested
both with and without CONFIG_MODVERSIONS.

kbuild: Generate *.lds instead of *.lds.s
When building a kernel on platforms where the filesytem do
not distingush between upper and lower case the rule:
.S -> .s did not work.
In a normal build this is only used for linker scripts.
So create a separate rule for .lds files, and use generic cpp flags.

kconfig/all archs: Introduce Kconfig.debug
Localize Kconfig debug options into one file (lib/Kconfig.debug)
for easier maintenance, searching, and menu-building.
Updated to 2.6.8.
Summary of changes:
. localizes the following symbols in lib/Kconfig.debug:
DEBUG_KERNEL, MAGIC_SYSRQ, DEBUG_SLAB, DEBUG_SPINLOCK,
DEBUG_SPINLOCK_SLEEP, DEBUG_HIGHMEM, DEBUG_BUGVERBOSE,
DEBUG_INFO
and FRAME_POINTER for some instances of it (if it's freely
user-selectable) but not for the cases where it's forced or
it depends on some other options.
. adds DEBUG_KERNEL requirement to some DEBUG_vars;
. remove KALLSYMS from S390-specific kernel hacking menu;
use KALLSYMS in the EMBEDDED menu instead;
. add CRIS and M68KNOMMU symbols for use in lib/Kconfig.debug;
. eliminate duplicate "General setup" labels in sparc64 config;
. whitespace cleanup;
. fixed a few trival typos;

[IPSEC]: Move encap check back down to esp4.c
In a previous, I moved the encap_type checks in esp4.c from the packet
processing path to xfrm_user/af_key. This isn't ideal since those encap
types only make sense for esp4.
The following patch moves it back into esp4.c. The difference is
that it's now done in init_state so that it's only done once rather
than per-packet.
I've also added encap_type checks for every transform. This means
that people attaching encap objects to AH/IPCOMP/IPIP will now get
errors. That should be fine as no major KM does this.
Please note that the error returned is now EINVAL instead of
ENOPROTOOPT. This shouldn't break anything since KMs only test
the errno from setsockopt() for NAT-T support rather than add_sa
where it would be too late anyway.

[PATCH] context-switching overhead in X, ioport()
while debugging/improving scheduling latencies i got the following
strange latency report from Lee Revell:
http://krustophenia.net/testresults.php?dataset=2.6.8.1-P...
this trace shows a 120 usec latency caused by XFree86, on a 600 MHz x86
system. Looking closer reveals:
00000002 0.006ms (+0.003ms): __switch_to (schedule)
00000002 0.088ms (+0.082ms): finish_task_switch (schedule)
it took more than 80 usecs for XFree86 to do a context-switch!
it turns out that the reason for this (massive) context-switching
overhead is the following change in 2.6.8:
[PATCH] larger IO bitmaps
To demonstrate the effect of this change i've written ioperm-latency.c
(attached), which gives the following on vanilla 2.6.8.1:
# ./ioperm-latency
default no ioperm: scheduling latency: 2528 cycles
turning on port 80 ioperm: scheduling latency: 10563 cycles
turning on port 65535 ioperm: scheduling latency: 10517 cycles
the ChangeSet says:
Now, with the lazy bitmap allocation and per-CPU TSS, this
will really not drain any resources I think.
this is plain wrong. An increase in the IO bitmap size introduces
per-context-switch overhead as well: we now have to copy an 8K bitmap
every time XFree86 context-switches - even though XFree86 never uses
ports higher than 1024! I've straced XFree86 on a number of x86 systems
and in every instance ioperm() was used - so i'd say the majority of x86
Linux systems running 2.6.8.1 are affected by this problem.
This not only causes lots of overhead, it also trashes ~16K out of the
L1 and L2 caches, on every context-switch. It's as if XFree86 did a L1
cache flush on every context-switch ...
the simple solution would be to revert IO_BITMAP_BITS back to 1024 and
release 2.6.8.2?
I've implemented another solution as well, which tracks the
highest-enabled port # for every task and does the copying of the bitmap
intelligently. (patch attached) The patched kernel gives:
# ./ioperm-latency
default no ioperm: scheduling latency: 2423 cycles
turning on port 80 ioperm: scheduling latency: 2503 cycles
turning on port 65535 ioperm: scheduling latency: 10607 cycles
this is much more acceptable - the full overhead only occurs in the very
unlikely event of a task using the high ioport range. X doesnt suffer
any significant overhead.
(tracking the maximum allowed port # also allows a simplification of
io_bitmap handling: e.g. we dont do the invalid-offset trick anymore -
the IO bitmap in the TSS is always valid and secure.)
I tested the patch on x86 SMP and UP, it works fine for me. I tested
boundary conditions as well, it all seems secure.

[PATCH] NMI trigger switch support for debugging(updated)
I made a patch for debugging with the help of NMI trigger switch.
When kernel hangs severely, keyboard operation(e.g.Ctrl-Alt-Del)
doesn't work properly. This patch enables debugging information
to be displayed on console in this case.
I think this feature is necessary as standard functionality.
Please feel free to use this patch and let me know if you have
any comments.
Background:
When a trouble occurs in kernel, we usually begin to investigate
with following information:
- panic >> panic message.
- oops >> CPU registers and stack trace.
- hang >> **NONE** no standard method established.
How it works:
Most IA32 servers have a NMI switch that fires NMI interrupt up.
The NMI interrupt can interrupt even if kernel is serious state,
for example deadlock under the interrupt disabled.
When the NMI switch is pressed after this feature is activated,
CPU registers and stack trace are displayed on console and then
panic occurs.
This feature is activated or deactivated with sysctl.
On IA32 architecture, only the following are defined as reason
of NMI interrupt:
- memory parity error
- I/O check error
The reason code of NMI switch is not defined, so this patch assumes
that all undefined NMI interrupts are fired by MNI switch.
However, oprofile and NMI watchdog also use undefined NMI interrupt.
Therefore this feature cannot be used at the same time with oprofile
and NMI watchdog. This feature hands NMI interrupt over to oprofile
and NMI watchdog. So, when they have been activated, this feature
doesn't work even if it is activated.
Supported architecture:
IA32
Setup:
Set up the system control parameter as follows:
# sysctl -w kernel.unknown_nmi_panic=1
kernel.unknown_nmi_panic = 1
If the NMI switch is pressed, CPU registers and stack trace will
be displayed on console and then panic occurs.

[PATCH] ppc32: optimize/fix timer_interrupt loop
The following patch fixes the situation where the loop condition could
generate a next_dec of zero while exiting the loop. This is suboptimal on
Classic PPC because it forces another interrupt to occur and reenter the
handler. It is fatal on Book E cores, because their decrementer is stopped
when writing a zero (Classic interrupts on a 0->-1 transition, Book E
interrupts on a 1->0 transition). Instead, stay in the loop on a
next_dec==0.

[PATCH] ppc64: Don't call scheduler on offline cpu
When taking a cpu offline, once the cpu has been removed from
cpu_online_map, it is not supposed to service any more interrupts. This
presents a problem on ppc64 because we cannot truly disable the
decrementer. There used to be cpu_is_offline() checks in several scheduler

offline a cpu can result in a crash in find_busiest_group(). This patch

[PATCH] ppc64: Extend ioremap/iounmap infrastructure
The patch below implements the ability to query outstanding imalloc regions
for a given virtual address range. (Imalloc is the allocator of virtual
space for ioremap.) The patch extends im_get_area() to allow a region
criterion of IM_REGION_SUPERSET. For a particular "superset" virtual
address and size passed into im_get_area(), the function returns the first
outstanding region that is contained within this superset region.
The patch also changes iounmap_explicit() to allow for the unmapping of all
regions that fit under a "superset".
This ability is necessary for dynamic (runtime) removal of pci host bridges
(PHBs). For a PHB removal, the platform specification (the RPA) requires
that all of its children slots already be dynamically removed. Each of
these slot-level removals has fractured the imalloc region assigned to the
PHB at boot. At PHB removal time, it is necessary to iounmap() the
remaining artifacts of the initial PHB region.

[PATCH] HVCS fixes
Here are a set of HVCS (drivers/char/hvcs.c) fixes that were suggested by Jeff
Garzik on July 29th in his review of this driver as well as some other fixes
for problems I found while reviewing the driver. These are all relatively
minor, but necessary.
- Cleaned up curly braces on single line conditional blocks.
- Replaced debug memset(...,0x3F,...) with memset(...,0x00,...).
- Removed explicit '= 0' after static int declarations since these default
to zero.
- Removed list_for_each_safe() instances and replaced with
list_for_each_entry() which cut down on amt of code. The 'safe' version is
un-needed now that the driver is using spinlocks.
- Changed spin_lock_irqsave() to spin_lock() when locking hvcs_structs_lock
and hvcs_pi_lock since these are not touched in an int handler.
- changed spin_lock_irqsave() to spin_lock() in interrupt handler.
- Initialized hvcs_structs_lock and hvcs_pi_lock to SPIN_LOCK_UNLOCKED at
declaration tiem rather than in hvcs_module_init().
- Added spin_lock around list_del() in destroy_hvcs_struct() to protect the
list traversal from deletion. The original omission was an oversight.
- Removed '= NULL' from pointer declarations since they are initialized NULL
by default.
- Removed wmb() instance from hvcs_try_write(). They probably aren't needed
with locking in place.
- Added check and cleanup for hvcs_pi_buff = kmalloc() in
hvcs_module_init().
- Exposed hvcs_struct.index via a sysfs attribute so that the coupling
between /dev/hvcs* and a vty-server can be systematically determined.
- Moved kobject_put() in hvcs_open() outside of the
spin_unlock_irqrestore().
- In hvcs_probe() changed kmalloc(sizeof(*hvcsd),...) to
kmalloc(sizeof(struct hvcs_struct)) because hvcsd references a NULL pointer
at the time of kmalloc.
- Incremented the HVCS_DRIVER_VERSION to 1.3.1
arch/ppc64/kernel/hvcserver.c:
- Changed function documentation of EXPORTed functions to comply with proper
kernel-doc documentation style.
- Changed 'unsigned int' types to 'uint32_t' to comply with how unit
addresses and partition IDs are handled in other arch/ppc64 vterm code.
- Cleaned up curly braces on single line conditional blocks.

This patch adds a memory barrier to ensure synchronization with the

[PATCH] i386 oops output: dump preceding code
This teaches the i386 oops dumper to dump opcodes preceding and after the
offending EIP. Supporting code against ksymoops has been tested and produces
output like the below.
Support for this was added to ksymoops-2.4.9.
Note that ksymoops will guarantee that the disassembly after the <eip> value
is always in sync - if the disassembly from the start of the Code: line does
not sync up with the EIP address ksymoops will perform the resync.

[PATCH] remove sync() from panic
Various people have reported deadlocks and it has aways seemed a bit risky
to try to sync the filesystems at this stage anyway.
"I have seen panic failing two times lately on an SMP system. The box
panic'ed but was running happily on the other cpus. The culprit of this
failure is the fact, that these panics have been caused by a block device
or a filesystem (e.g. using errors=panic). In these cases the likelihood
of a failure/hang of sys_sync() is high. This is exactly what happened in
both cases I have seen. Meanwhile the other cpus are happily continuing
destroying data as the kernel has a severe problem but its not aware of
that as smp_send_stop happens after sys_sync."

[PATCH] Fix x86-64 singlestep through sigreturn system call
This patch just directly clones Davide Libenzi's i386 code for x86-64 in
both 64-bit and 32-bit cases. With this, the behavior of single-stepping
all system calls is consistent.
The syscall exit tracing caused by TIF_SINGLESTEP is superfluous in the
case of sysret returns, but harmlessly so (since continuing afterward with
PTRACE_CONT will have cleared TF as well as TIF_SINGLESTEP). I figured
that little bit of extra processing in the single-step case was better than
adding code to ignore the flag in the sysret case.

[PATCH] Subject: cdrom.c get_last_written fixup
There's something wrong in cdrom.c: cdrom_get_last_written() for instance
calls cdrom_get_disc_info() and cdrom_get_track_info() to get information
about tracks, but these functions don't ensure that all the
track_information or disc_information structure is filled:
/* (buflen was first set to 8 to get track_information_length field) */
if ((ret = cdo->generic_packet(cdi, &cgc)))
return ret;
cgc.buflen = be16_to_cpu(ti->track_information_length) +
sizeof(ti->track_information_length);
if (cgc.buflen > sizeof(track_information))
cgc.buflen = sizeof(track_information);
cgc.cmd[8] = cgc.buflen;
return cdo->generic_packet(cdi, &cgc);
The second test ensures that at least we won't overflow the structure, but
nothing ensures that all the structure will be filled.
And indeed, we have a drive here that won't fill it all: the returned
track_information_length field will be *less than*
sizeof(track_information) - sizeof(ti->track_information_length), so that
cdrom_get_last_written() reads values that weren't filled in! As a result,
we are sometimes unable to read some parts of CDROMs, depending on the
uninitialized state of the structure...
Here is a patch that adds filling checks: cdrom_get_disc_info() and
cdrom_get_track_info() return the actual filled length, and it's up to the
caller to check that this is enough for him to get the values it wants.
Note: adding something like a
#define spanof(TYPE, MEMBER) ((size_t) ((&((TYPE *)0)->MEMBER)+1))
definition just near that of offsetof() in include/linux/stddef.h would
make it more pretty, but still it won't help for bitfields :/

[PATCH] get_random_bytes() returns the same on every boot
At boot time, get_random_bytes always returns the same random data, as if
there were a constant random seed. For example, if I use the kernel level
ip autoconfiguration with dhcp, the kernel will create a dhcp request
packet with always the same transaction ID. (If you have more than one
computers, and they are booting at the same time, then this is a big
problem)
That happens, because only the primary entropy pool is initialized with the
system time, in function rand_initialize. The secondary pool is only
cleared. In this early stage of booting, there is usually no user
interaction, or usable disk interrupts, so the kernel can't add any real
random bytes to the primary pool. And altough the system time is in the
primary pool, the kernel does not consider it real random data, so you
can't read from the primary pool, before at least a part of it will be
filled with some real randomness (interrupt timing). Therefore all random
data will come from the secondary pool, and the kernel cannot reseed the
secondary pool, because there is no real randomness in the primary one.
The solution is simple: Initialize not just the primary, but also the
secondary pool with the system time.

[PATCH] make shrinker_sem an rwsem
Use an rwsem to protect the shrinker list instead of a regular

shrink_slab takes the read lock, and access to shrinker->nr becomes racy

shrinker functions become concurrent.
Previously, having the slab scanner get preempted or scheduling while
holding the semaphore would cause other tasks to skip putting pressure on
the slab.
Also, make shrink_icache_memory return -1 if it can't do anything in order
to hold pressure on this cache and prevent useless looping in shrink_slab.

[PATCH] break out zone free list initialization

zone_init_free_lists(). It also creates pages_to_bitmap_size(), which is

area bitmap resizing patch.
First of all, I think it looks nicer this way, but it's also necessary to
have this if you want to initialize a zone after system boot, like if a
NUMA node was hot-added. In any case, it should be functionally equivalent
to the old code.

[PATCH] fbcon: ifferentiate bits_per_pixel from color depth
1. If you remember this thread (HP300 support checked in), one concern
was how to support framebuffers with bpp == 8 but color depth < 8
(chunky layout). I suggested to use the fields in var->{red|green|blue}
to differentiate between bits_per_pixel and depth. Included is a patch
that does that.
(The above assumes background/foreground of 0/1. If hardware needs a
different value, such as 0 - black, 0xff - white, just indicate
TRUECOLOR or DIRECTCOLOR and set info->pseudopalette correctly in
xxxfb_setcolreg().)
The patch will break the following drivers when in monochrome since
they do not set the proper color bitfields. I've included a fix in
patch #2.
68328fb
bw2fb
cirrusfb
dnfb
macfb
stifb
tx3912fb
2. Besides the change above, support for the inverse and underline
attribute is added in monochrome mode. One should get text which are
underlined/reversed if the corresponding attribute is set.
3. Because vt.c uses a 16-color palette, use fbcon_default_cmap if
framebuffer can do less than 16 colors. In 4 colors, display will be
grayscaled. In 8 colors, display should have the same colors as a
16-color console but will lack brightness/ intensity.
4. Fix monochrome logo drawing.
5. Reduce code of fbcon_putc so it just calls fbcon_putcs.

8-bit DAC will also provide a wider color range for user applications.

[PATCH] rivafb: directcolor mode and miscellaneous fixes
Although the rivafb advertises its capability as DirectColor, the hardware
is actually set in Truecolor (CLUT cannot be altered). This mismatch
occasionally produces wrong colors, such as wrong logo colors at 32bpp and
gamma utilities (such as xgamma) does not work at all.
Changes:
1. Fixes the above problems by setting the hardware to accept changing
of the CLUT.
2. Fixes color problems for NV_ARCH_03 (Riva128)
3. Build a private modelist from the EDID (for use by fbcon)
4. Mark several functions/data as __devinit/__initdata
5. Remove unused fields from struct riva_par

[PATCH] RCU: low latency rcu
This patch makes RCU callbacks friendly to scheduler. It helps low latency
by limiting the number of callbacks invoked per tasklet handler. Since we
cannot schedule during a single softirq handler, this reduces size of

The limiting is done through a kernel parameter rcupdate.maxbatch which is
the maximum number of RCU callbacks to invoke during a single tasklet
handler.

code and making the code simpler. I had already done that for the rcu-softirq
patch earlier, so I am splitting that into two patch. This first patch cleans
up the macros and uses pointers to the rcu per-cpu data directly to manipulate
the callback queues. This is useful for the call-rcu-bh patch (to follow)
which introduces a new RCU mechanism - call_rcu_bh(). Both generic and
softirq rcu can then use the same code, they work different global and percpu
data.

[PATCH] rcu: introduce call_rcu_bh()
Introduces call_rcu_bh() to be used when critical sections are mostly in
softirq context.
This patch introduces a new api - call_rcu_bh(). This is to be used for RCU
callbacks for whom the critical sections are mostly in softirq context. These
callbacks consider completion of a softirq handler to be a quiescent state.
So, in order to make reader critical sections safe in process context,
rcu_read_lock_bh() and rcu_read_unlock_bh() must be used. Use of softirq
handler completion as a quiescent state speeds up RCU grace periods and
prevents too many callbacks getting queued up in softirq-heavy workloads like
network stack.

[PATCH] token based thrashing control
The following experimental patch implements token based thrashing
protection, using the algorithm described in:
http://www.cs.wm.edu/~sjiang/token.htm
When there are pageins going on, a task can grab a token, that protects the
task from pageout (except by itself) until it is no longer doing heavy
pageins, or until the maximum hold time of the token is over.
If the maximum hold time is exceeded, the task isn't eligable to hold the
token for a while more, since it wasn't doing it much good anyway.
I have run a very unscientific benchmark on my system to test the
effectiveness of the patch, timing how a 230MB two-process qsbench run
takes, with and without the token thrashing protection present.
normal 2.6.8-rc6: 6m45s
2.6.8-rc6 + token: 4m24s
This is a quick hack, implemented without having talked to the inventor of
the algorithm. He's copied on the mail and I suspect we'll be able to do
better than my quick implementation ...

[PATCH] Concurrent O_SYNC write support
In databases it is common to have multiple threads or processes performing
O_SYNC writes against different parts of the same file.
Our performance at this is poor, because each writer blocks access to the
file by waiting on I/O completion while holding i_sem: everything is
serialised.
The patch improves things by moving the writing and waiting outside i_sem.
So other threads can get in and submit their I/O and permit the disk
scheduler to optimise the IO patterns better.
Also, the O_SYNC writer only writes and waits on the pages which he wrote,
rather than writing and waiting on all dirty pages in the file.
The reason we haven't been able to do this before is that the required walk
of the address_space page lists is easily livelockable without the i_sem
serialisation. But in this patch we perform the waiting via a radix-tree
walk of the affected pages. This cannot be livelocked.
The sync of the inode's metadata is still performed inside i_sem. This is
because it is list-based and is hence still livelockable. However it is
usually the case that databases are overwriting existing file blocks and
there will be no dirty buffers attached to the address_space anyway.
The code is careful to ensure that the IO for the pages and the IO for the
metadata are nonblockingly scheduled at the same time. This is am improvemtn
over the current code, which will issue two separate write-and-wait cycles:
one for metadata, one for pages.
Note from Suparna:
Reworked to use the tagged radix-tree based writeback infrastructure.

of the arguments a bit of code with a conditional return).
We could further parametrize DefineCacheLookup, but I think it's already too
complicated.
My solution is to just ignore DefineCacheLookup and write the
auth_domain_lookup function from scratch. It's actually a pretty short
function (much simpler than DefineCacheLookup itself), and it's much easier to
read this short function than it is to read some special-cased
DefineCacheLookup to verify that it does what it says it does....

[PATCH] kNFSd: fix race with flushing nfsd cache.
To purge an nfsd-authentication cache, we set the flush time to later than
last-refresh time in the cache and call cache_flush. The easiest way to
find 'later than last-refresh' is 'now+1'.
This has two problems.
1/ if the time-of-day clock has gone bacwards, some entries might not
be purged
2/ if a new entry is added in the same second as cache_purge ran, it will
get ignored.
To resolve these issues, we set the flushtime to the maximum possible time
before calling cache_flush, and then set it back to the minimum time
afterwards.

[PATCH] IPMI driver updates
Some people found some bugs and some missing functions in the IPMI driver,
so I have patching things together for the next release. The attached
patch moves to version 33 of the driver and contains:
* SMBIOS table support for specifying register spacing. This allows
non-contiguous registers to be specified and some machines do
this.
* ACPI table updates to support all the possible register sizes and
bit offsets into the registers for the IPMI information.
* Support for command line parameters to specify register
spacing, sizes, and bit offsets.
* Support for power control with IPMI. This allows a halt to
power down a machine with IPMI.
* A fix for a race condition with interrupts enabled on an
SMP machine. A lock was released then reclaimed, but
there was code later that assumed that had not happened.
* A fix for protecting the driver against bad responses from
the controller chip. In the past, the driver had assumed that
the controller chip would not give it bad data. This has
turned out to be a bad assumption
* ACPI interrupt handlers now return a return value, adjust
accordingly.
Thank you to all the people who helped me with this.

[PATCH] DIO pages-in-io accounting fix
I found one more accounting inconsistency with dio_pages_in_io. This is a
day-one bug and I started hitting it on latest -mm due to the recent
changes to dio_pages_in_io calculations to be exact.
If the file is badly fragmented (no contiguous blocks at all), and the user
buffer is not page aligned - we need to create IO for each disk block with
2 pages. (bio with 2 vecs).
dio_bio_add_page() should not decrement dio_pages_in_io for every add page.
It should only decrement, it only if its done with that page and moving on
to next page. (since dio_pages_in_io represent how many actual pages we
are operating on).
Here is the patch to fix this accounting. Without this patch, we will hit
BUG() in dio_new_bio() with O_DIRECT on filesystems.

[PATCH] aio.c: rename 'struct timeout' to 'struct aio_timeout'
This patch renames fs/aio.c:'struct timeout' to 'struct aio_timeout'. The
rationale behind this decision is this type is used only inside the
aforementioned aio.c file and being the type name very generic, it is
likely to cause namespace conflicts in the future.
I actually found it while working on an extended schedule_timeout()- like
API used by robust mutexes but usable by anyone. There I declared a
'struct timeout' and aio.c complained about it. I could have also renamed
the struct for the schedule_timeout() like API, but being the aio.c one
specific to the file, I thought it might make more sense to rename the
later.

[PATCH] readahead fixes
Here is a consolidated readahead patch that takes care of the performance
regression seen with multiple threaded writes to the same file descriptor.
The patch does the following:
1. Instead of calculating the average count of sequential
access in the read patterns, it calculates the
average amount of hits in the current window.
2. This average is used to guide the size of the next current
window.
3. Since the field serial_cnt in the ra structure does not
make sense with the introduction of the new logic,
I have renamed that field as currnt_wnd_hit.
This patch will help the read patterns that are not neccessarily sequential
but have sufficient locality. However it may regress random workload.
Results:
1. Berkley Shands has reported great performance with this
patch.
2. iozone showed negligible effect on various read patterns.
3. DSS workload saw neglible change.
4. Sysbench saw a small improvement.

[PATCH] rlimit-based mlocks for unprivileged users
Here is the last agreed-on patch that lets normal users mlock pages up to
their rlimit. This patch addresses all the issues brought up by Chris and
Andrea.
From: Chris Wright <chrisw@osdl.org>
Couple more nits.
The default lockable amount is one page now (first patch is was 0). Why
don't we keep it as 0, with the CAP_IPC_LOCK overrides in place? That way
nothing is changed from user perspective, and the rest of the policy can be
done by userspace as it should.
This patch breaks in one scenario. When ulimit == 0, process has
CAP_IPC_LOCK, and does SHM_LOCK. The subsequent unlock or destroy will
corrupt the locked_shm count.
It's also inconsistent in handling user_can_mlock/CAP_IPC_LOCK interaction
betwen shm_lock and shm_hugetlb.
SHM_HUGETLB can now only be done by the shm_group or CAP_IPC_LOCK.
Not any can_do_mlock() user.
Double check of can_do_mlock isn't needed in SHM_LOCK path.
Interface names user_can_mlock and user_substract_mlock could be better.
Incremental update below. Ran some simple sanity tests on this plus my
patch below and didn't find any problems.
* Make default RLIM_MEMLOCK limit 0.
* Move CAP_IPC_LOCK check into user_can_mlock to be consistent
and fix but with ulimit == 0 && CAP_IPC_LOCK with SHM_LOCK.
* Allow can_do_mlock() user to try SHM_HUGETLB setup.
* Remove unecessary extra can_do_mlock() test in shmem_lock().
* Rename user_can_mlock to user_shm_lock and user_subtract_mlock
to user_shm_unlock.
* Use user instead of current->user to fit in 80 cols on SHM_LOCK.

[PATCH] increase per-user mlock limit default to 32k
Since various gnupg users have indicated that gpg wants to mlock 32kB of

This is no security problem because it's trivial for processes to lock way
more memory than this in page tables, network buffers, etc. In fact, since
this patch allows gnupg to mlock to prevent passphrase data from being
swapped out, the security people will probably like it ;)

VFS,CIFS,NLM,NFSv4: make filesystems directly responsible for calling
posix_lock_file() if they need it. This fixes an NFS race whereby
in case of a server reboot, the recovery thread could re-establish
a lock that had just been freed.

[PATCH] Fix posix file locking (9/9)
NFSv2/v3: Fix up a race in the case where the user presses ^C while a

server registered our lock, we need to make sure that it gets
cleaned up during the resulting file close().

NFS: In 2.4, NFS O_DIRECT used the VFS's O_DIRECT logic to provide
direct I/O support for NFS files. The 2.4 VFS O_DIRECT logic was
block based, thus the NFS client had to provide a minimum
allowable blocksize for O_DIRECT reads and writes on NFS files.
For various reasons we chose 512 bytes. In 2.6, there is no
requirement for a minimum blocksize. NFS O_DIRECT reads and
writes can go to any byte at any offset in a file. Thus we revert
the blocksize setting for NFS file systems to the previous
behavior, which was to advertise the "wsize" setting as the
optimal I/O block size. This improves the performance of
applications like 'cp' which use this value as their transfer
size.
This patch also exposes the server's reported disk block size in the
f_frsize of the vfsstat structure.

NFS: While the storage container for NFS file handles must be able to

NFSv2: In the NFSv3 RFC, the sattr3 structure passed in the SETATTR
call allows for the client to request that the mtime and/or atime
of an inode be set to the current server time, the given (client)
time, or not changed. The set-to-current-server value is used
when you run "touch file" on the client.
The NFSv2 RFC defines no such encoding for the sattr structure.
However Solaris and Irix machine obey a convention where passing
the invalid value mtime.useconds=1000000 means "set both mtime and
atime to the current server time". The convention is documented
in the book "NFS Illustrated" by Brent Callaghan. The patch below
implements this convention for the Linux client and server (hence
multiple To:s).
