2.6.6-rc2 long-format changelog
Summary of changes from v2.6.6-rc1 to v2.6.6-rc2
============================================
<kberg@linux1394.org>
[IEEE1394/OHCI]: Deal with some OHCI implementations that have an invalid max_rec field.
<weihs@linux1394.org>
IEEE1394/Lynx(r1182): Explicitly set LCtrl bit in phy register set.
<mchan@broadcom.com>
[TG3]: Jumbo frames and FTQ reset patch.
1. Set extended packet length bit in phy register 0x18 shadow register 0
on all chips that support jumbo frames (i.e. all chips except 5705 and
its variants). Jumbo frame reception is less reliable (more CRC errors)
if this bit is not set. This bit can be set regardless of the current
MTU setting.
2. Remove FTQ reset during chip init. This is the best fix for the ASF
race condition problem that I mentioned a few months ago. The FTQ reset
is redundant as it is already reset during GRC reset.
<davem@nuts.davemloft.net>
[TG3]: Just completely delete the disabled FTQ reset code.
<greg@kroah.com>
Driver Core: fix spaces instead of tabs problem in the Kconfig file.
<greg@kroah.com>
add sysfs support for vc devices.
<greg@kroah.com>
VC: fix bug in vty_init() where vcs_init() was not called early enough.
It was being used before initialized, not nice :(
<greg@kroah.com>
Driver class: remove possible oops
This happens when the device associated with a class device goes away before
the class does.
<hannal@us.ibm.com>
[PATCH] QIC-02 tape drive hookup to classes in sysfs
Here is a patch to hook up the qic02 tape device to have class
support in sysfs. I have verified it compiles. I do not have access to
the hardware to test. Could someone who does please verify?
From the file:
* This is a driver for the Wangtek 5150 tape drive with
* a QIC-02 controller for ISA-PC type computers.
* Hopefully it will work with other QIC-02 tape drives as well.
<hannal@us.ibm.com>
[PATCH] add class support to floppy tape driver zftape-init.c
Here is a patch to add class support to zftape-init.c:
MODULE_DESCRIPTION(ZFTAPE_VERSION " - "
"VFS interface for the Linux floppy tape driver. "
"Support for QIC-113 compatible volume table "
"and builtin compression (lzrw3 algorithm)");
I have verified it compiles but do not have the hardware to test it.
<kronos@kronoz.cjb.net>
[PATCH] Sysfs for framebuffer
the following patch (against 2.6.5-rc2) teaches fb to use class_simple.
With this patch udev will automagically create device nodes for each
framebuffer registered. Once all drivers are converted to
framebuffer_{alloc,release} we can switch to our own class.
This is what sysfs dir looks like:
notebook:~# tree /sys/class/graphics/
/sys/class/graphics/
`-- fb0
`-- dev
<jgarzik@redhat.com>
Remove mention of non-existent tulip.txt from Doc/netwrk/00-INDEX
<jgarzik@redhat.com>
[BK] ignore build-generated files in scripts/basic/ and drivers/md/
<jgarzik@redhat.com>
[MAINTAINERS] remove mention of defunct linux-via mailing list
Noticed by Adrian Bunk.
<hannal@us.ibm.com>
[PATCH] added class support to stallion.c
Here is a patch to add class support to the Stallion multiport
serial driver.
<hannal@us.ibm.com>
[PATCH] added class support to istallion.c
Here is a patch to add class support to the Stallion Intelligent multiport
serial driver.
<romain@lievin.net>
[PATCH] tipar char driver (divide by zero)
A patch about the tipar.c char driver has been sent on lkml by Sebastien
Bourdeau. It fixes a divide-by-zero error when we try to read/write data
after setting the timeout to 0.
<greg@kroah.com>
PCI: add ability to access pci extended config space for PCI Express devices
Patch originally written by Intel, cleaned up and made sane by
Matthew Wilcox <willy@debian.org> and then tweaked a bit more by me.
From Matt's original email:
- Add cfg_size to struct pci_dev.
- Use it in sysfs and procfs.
- Introduce pci_find_ext_capability() for finding extended capabilities.
- Change the PCI_X_STATUS defines to match the spec (mea culpa there).
- Add defines for the extended capabilities.
<dlsy@snoqualmie.dp.intel.com>
[PATCH] PCI: Updates for PCI Express hot-plug driver
<willy@debian.org>
[PATCH] PCI Hotplug: Don't up() twice in acpiphp
On the error path, we currently try to up() a semaphore twice.
There was also a typo in an error message.
<willy@debian.org>
[PATCH] PCI Hotplug: Rewrite acpiphp detect_used_resource
There are two unrelated problems in acpiphp that are fixed by this patch.
First, acpiphp can be a module, so it is unsafe to probe the BARs of each
device while it initialises -- the device may be active at the time.
Second, it does not know about PCI-PCI bridge registers and so it reads
garbage for the last 4 registers of the PCI-PCI bridge card and doesn't
take into account the ranges that are forwarded by the bridge.
This patch avoids all that by using the struct resources embedded in
the pci_dev. Note that we no longer need to recurse as all the devices
on the other side of a PCI-PCI bridge have their resources entirely
contained within the PCI-PCI bridge's ranges.

Here's an updated patch, applies to 2.6.5-rc2-bk9.
I left the DMA_xxBIT_MASK defines in linux/pci.h, although
they aren't necessarily PCI-specific. Would we prefer to
have them in linux/dma-mapping.h ?

[PATCH] PCI Hotplug: RPA PCI Hotplug - redundant free
Please commit the following patch, which removes a redundant call to a
cleanup function from an error path of the module init code.
<dsaxena@plexity.net>
[PATCH] PCI: Allow arch-specific pci_set_dma_mask and friends
The patch provides the ability for architectures to have custom
implementations of pci_set_dma_mask() and friends (dac_set_dma_mask
and set_consistent_dma_mask). The reason I need this is b/c I have
a chipset (Intel ARM IXP425) that has a broken PCI interface that
only allows PCI dma to/from the bottom 64MB of system memory. To get
around this limitation, I trap a custom dma-mapping implementation that
bounces buffers outside the 64MB window. At device discover time, my
custom platform_notify() function gets called and it sets the dma_mask
to (64MB-1) and in ARM's dma-mapping code, I check for dma_mask != 0xffffffff
and if that is true, I call the special bounce helpers. This works great
except that certain drivers (e100, ide-pci) call pci_set_dma_mask()
with 0xffffffff and the generic implementation only allows for the
architecture-defined pci_dma_supported() to return true or false. There
is no method for the architecture to tell the PCI layer "I can't set
the mask to 0xffffffff, but I can set it to this other value" and there
is no way to pass that back to the driver. What this means is that if
I have pci_set_dma_supported() return failure on full 32-bit DMA, the
driver will not initialize the card; however, if I return true,
pci_set_dma_mask() will set the dma mask to full 32-bits and I can no
longer trap and will have buffers that are not dma-able and cause
PCI master aborts. Both of those are not acceptable. IMHO, the
driver shouldn't care if the architecture has to bounce DMA outside of
64MB and since this is not something most architectures have to worry
about, the easiest way to get around the issue is by allowing custom
pci_set_dma_mask() for arches that need it but keeping the generic
implementation for those that do not. In my case, it simply returns
0 to the driver but keeps the device mask set to 64MB-1 so I can trap.
<lxiep@ltcfwd.linux.ibm.com>
[PATCH] kobject_set_name() doesn't allocate enough space
<ahaas@airmail.net>
[SPARC]: Add C99 initializers to Sparc frame buffer devices.
<shemminger@osdl.org>
[NET]: Mark lock_sock and release_sock as FASTCALL.
<mludvig@suse.cz>
[AF_KEY]: pfkey_send_new_mapping marks dest address incorrectly.
<davem@nuts.davemloft.net>
[TG3]: Verify link advertisement correctly on 10/100 only chips.
<dlstevens@us.ibm.com>
[IPV4]: Fix IGMP version number and timer printing for procfs.
<shemminger@osdl.org>
[BRIDGE]: Allow non-root to inspect the status of a bridge.
<davem@nuts.davemloft.net>
[TG3]: All 5705 chips need PHY reset on link-down.
<shemminger@osdl.org>
[BRIDGE]: Lift ioctl limits on number of bridges/ports.
Get rid of some arbitrary API restrictions that limit the kernel
to 64 bridges and 256 ports.
Retain compatibility in GET_PORT_LIST, the existing bridge API
passes 0 for the third argument, and expects 256 entries.
Note: there still is limit of 256 ports due to STP, but this
shouldn't show up in the API, it needs to be handled by the
'add port to bridge ioctl'.
<shemminger@osdl.org>
[BRIDGE]: Correctly handle up to 256 ports per bridge.
Bridge code is limited to 256 ports per bridge because the Spanning
Tree Protocol has limit of one octet for port number. This code
fixes:
* bogus unlock in error path when port list is full.
* passes different error status for out of memory, vs
port list full.
* O(n) vs O(n^2) lookup for free port number
* since port and priority are both limited to one byte
don't store them as int's
* makes limit explicit in code
<davem@nuts.davemloft.net>
[TG3]: More PHY programming fixes.
- Break out advertisement register verification into
a function, tg3_copper_is_advertising_all.
- At device probe time, reset PHY if not Serdes
and ASF is not enabled.
- Add some missing necessary PHY init to PHY probe
code as well.
<davem@nuts.davemloft.net>
[TG3]: Bump driver version and reldate.
<davem@nuts.davemloft.net>
[TG3]: Print list of important probed capabilities at driver load.
<davem@nuts.davemloft.net>
[TG3]: Two PHY fixes.
- Do not probe PHY ID register if ASF firmware is running.
- Fix two errors in PCI subsys to PHY ID table.
<davem@nuts.davemloft.net>
[TG3]: Kill uninitialized var warning.
<davem@nuts.davemloft.net>
[TG3]: Reset fixes.
- Put more code into common area in tg3_chip_reset()
- Set GRC_MODE, even sanes host-stackup bit, after enabling
memory arbiter.
- After every core-clock reset, reprobe ASF enabling state.
<davem@nuts.davemloft.net>
[TG3]: Update driver version and release date.
<mashirle@us.ibm.com>
[IPV6]: Add MIBs counters in MLD.
<ebrower@usa.net>
[SPARC]: Add sysctl to control serial console power-off restrictions.

[SPARC64]: hugetlbpage.c needs module.h
<marcel@holtmann.org>
[Bluetooth] Remove architecture specific compat ioctl's
The compat ioctl definitions are now maintained in a single place, so
it is no longer needed to keep the architecture specific defines. This
patch removes the leftover Bluetooth parts from x86_64 and sparc64.
<marcel@holtmann.org>
[Bluetooth] Fix broken HCI security filter
The HCI security filter is broken on 64-bit architectures and this patch
restores the version from 2.4, which is working perfect on 32-bit and
64-bit machines.
<marcel@holtmann.org>
[Bluetooth] Allocate hdev before device configuration
The hdev structure must be allocated before the device is configured and
before any interrupt is started.
<marcel@holtmann.org>
[Bluetooth] Add UART protocol id's for 3-Wire and H4DS
This patch adds the id's for the 3-Wire and H4DS UART transport protocols.
<mashirle@us.ibm.com>
[IPV6]: Provide ipv6 multicast/anycast addresses through netlink.
<manfred@colorfullife.com>
[NETLINK]: Split up netlink_unicast.
<rddunlap@osdl.org>
[NET]: Update networking config menu (v3)
Networking support/options and Networking drivers have been, uhm,
messy to navigate for some time now. BenH mentioned this
and I was already looking into options to clean it up.
This is a cleanup of Networking support/options and Networking Drivers.
It presents a more consistent interface and lists similar driver
groups and protocol groups closer together.
It also moves the IBMVETH driver so that it no longer breaks the
dependency tree, allowing other drivers (nearby in Kconfig file)
to be presented in a more linear manner.

[SCTP] Update sctp_ulpevent structure to include assoc pointer and
only the receive specific fields of sctp_sndrcvinfo.
<sri@us.ibm.com>
[SCTP] Use id to ptr translation service in lib/idr.c to assign and
validate ids of associations.
This patch avoids the use of virt_addr_valid() to validate the address
of associations passed by the user. Currently the address of an
association is used as its id. virt_addr_valid doesn't work as
expected when PAGEALLOC debugging is enabled.
<marcel@holtmann.org>
[Bluetooth] Allocate the BCM203x URB buffer seperately
The buffer shares cachelines with other fields of the structure. On
architectures which require synchronisation before or after doing DMA
to or from a buffer, any access to such fields sharing cachelines can
corrupt the content of the buffer. The allocation primitives guarantee
that cachelines are not shared.

[PATCH] Add sysfs class support to fs/coda/psdev.c
Here is a patch to add class support to psdev.c.
I have verified it compiles and works.
<marcel@holtmann.org>
[Bluetooth] Fix URB unlink race in the USB drivers
The code in hci_usb_unlink_urbs() calls usb_unlink_urb() to perform a
synchronous unlink of each pending URB. It then moves each URB to the
completed list, and then frees everything on the completed list. By doing
this, the code implicitly assumes that when usb_unlink_urb() returns the
URB will have completed and be ready to be deallocated. That's not always
true. The same applies to the BlueFRITZ! USB driver.
Patch from Alan Stern <stern@rowland.harvard.edu>
<marcel@holtmann.org>
[Bluetooth] Make use of request_firmware() for the 3Com driver
The 3Com Bluetooth PCMCIA cards need a firmware download every time they
are inserted. With request_firmware() the file BT3CPCC.bin is now loaded
directly from the userspace and the external firmware loader program is
no longer needed.
<marcel@holtmann.org>
[Bluetooth] Improve NULL pointer handling
This small patch adds more checks for NULL pointers.
<marcel@holtmann.org>
[Bluetooth] Add support for Anycom CF-300
The Anycom CF-300 compact flash card contains a new Bluetooth chip and
thus it needs some special handling for the faster UART baud rate. This
patch detects this new card and does the different initialization.

[Bluetooth] Allow normal users to release the previous created TTY
In the case the RFCOMM device node can't be found, the user must be able to
release the previous created TTY.
<marcel@holtmann.org>
[Bluetooth] Fix race in RX complete routine of the USB drivers
The test of the HCI_RUNNING flags bit in the RX complete routine should
be made while holding the completion lock. Otherwise there can be a race
on SMP systems in which RX complete finds the bit is set and on another
processor the close routine clears the bit, grabs and releases the lock
and then unlinks all the active URB's. Then the first processor acquires
the lock and resubmits the URB.

this patch fixes a bug in the CAPI TTY support, because the ->name value

the control device to "capi". The userspace visible part must be done by

[PATCH] mq_open() and close_on_exec
From: Chris Wright <chrisw@osdl.org>
SUSv3 doesn't seem to specify one way or the other. I don't have the POSIX
specs, and the old docs I have suggest that mq_open() creates an object
which is to be closed upon exec.
Jakub said:
I think it is valid and required:
http://www.opengroup.org/onlinepubs/007904975/functions/exec.html
All open message queue descriptors in the calling process shall be
closed, as described in mq_close()
I'll add a new test for this into glibc testsuite.

[PATCH] ext3: journalled quotas
From: Jan Kara <jack@ucw.cz>
Journalled quota support for ext3: The patch consists of two parts - ext3
changes and changes in generic quota code. The main idea of the changes is
that a transaction is always started before any operation which changes quota
file and dirtifying of the quota causes its write to disk. These two changes
assure that quota change is journalled into the same transaction as the file
change and hence after journal replay quota is consistent with the filesystem
state. As during journal replay inodes from orphan list are deleted/truncated
we have to do quota_on before the replay of the orphan list - this problem is
solved by additional mount options to ext3 with quota file names and format.
Some changes in generic code were also needed to assure that quota structure
in file is always allocated and so ordinary quota operations (like
adding/deleting a block/inode) need only a few blocks from the transaction.

[PATCH] ppc64: Fix possible duplicate MMU hash entries
The current code has a subtle race where 2 hash PTEs can be inserted
for the same virtual address for a short period of time. There should
not be a stale one as the "old" one ultimately gets flushed, but the
architecture specifies that having two hash PTE is illegal and can
result in undefined behaviour.
This patch fixes it by never clearing the _PAGE_HASHPTE bit when
doing test_and_clear_{young,dirty}. That means that subsequent faults
on those pages will have a bit more overhead to "discover" that the
hash entry was indeed evicted.
It also adds a small optisation to avoid doing the atomic operation
and the hash flush in test_and_clear_dirty when the page isn't dirty
or when setting write protect while it's already set.
<benh@kernel.crashing.org>
[PATCH] ppc64: update g5_defconfig
This adds IOMMU support & IOMU virtual merging to the default g5 config.
This will not impair performances of machines that don't need the iommu
(the kernel will only enable it if you have more than 2Gb of RAM, though
you can explicitely enable it using a command line argument).
<James.Bottomley@SteelEye.com>
[PATCH] fix 4k irqstacks on x86 (and add voyager support)
There's a bug in the x86 code in that it sets the boot CPU to zero.
This isn't correct since some subarch's use physically indexed CPUs.
However, subarchs have either set the boot cpu before irq_INIT() (or
just inherited the default zero from INIT_THREAD_INFO()), so it's safe
to believe current_thread_info()->cpu about the boot cpu.

[PATCH] fix non-PC subarchs which were broken by i386 probe_roms change
The author apparently didn't understand that only the mach-default
include directory is included by fallback for header files only. You
can't stick a .c file in mach-default and expect all subarchs to be able
to use it.
The correct fix is to put std_resources.c in the kernel directory and
give it its own Kconfig symbol for conditional compile so that subarchs
may choose to include it or not.

[PATCH] NMI watchdog Pentium M support
This adda nmi_watchdog=2 support to the Pentium M processor. The P-M is
a P6 chip, but it shares some chipset logic with the Pentium 4, so it
requires this workaround to function.
Without this patch, NMI gets stuck after 1 count. With it, the NMI
fires and breaks me out of UHCI-related hard lockups.
This patch is basically a modified version of the same patch for
oprofile. See the threaded discussion here:

[PATCH] ppc64: catch branch to 0 in real mode
We have been debugging some strange fails where we branch to 0 in real

The following patch uses the featuring nop'ing code to remove the branch
at real address 0 so it falls through to a trap instruction and gets
caught early.

[PATCH] ppc64: Fix RTAS races on pSeries
The low level kernel interface to RTAS (the firmware runtime services)
was plagued with races that could cause from bogus results of RTAS
operations to total machine crashes in some circumstances. This patch
fix the ones I could identify, hoping I didn't miss any. I also added
a WARN_ON (well, it's asm equivalent) to enter_rtas to make sure we
never _ever_ try to call that with interrupts enabled.

[ARM] Add --no-undefined to linker command line.
Many binutils versions over the last year appear to silently build
assembler files with undefined constants, and able to successfully
create executables from such files. The assembler appears to add
undefined symbols to the symbol table without any corresponding
relocation information. Obviously this is bad news since the
resulting executable may not be what the programmer intended.
Work around the problem by forcing the linker to fail if there are
any undefined symbols in the final object(s).

[PATCH] remount: fs/sysv fixes
- several variants of sysv fs are supported only r/o. Driver does
force r/o on mount, but doesn't do anything on remount. As the
result, one can remount them r/w and results are Not Pretty(tm).
Missing checks added, code cleaned up.
- we had double-brelse() in v7fs - if sanity checks on root inode will
succeed, but allocation of root dentry fails, we brelse() the same
buffer_head twice. Fixed.

- jff2->remount_fs() was buggy - it played with sb->s_flags instead of
doing modifications to *flags (->s_flags will be overwritten using

to do the wrong thing - it should just enforce noatime and be done
with that. Fixed, ACKed by maintainer.

[PATCH] remount: mount flags filtering
- we could pass MS_ACTIVE in mount flags and it would be passed into
->get_sb(), leading to interesting failure modes. This flag is only
for internal use (it's set once fill_super is complete and reset
before the inode eviction on umount); made sure that we never get
tricked into having it set it too early.

[PCMCIA] Conversion to module_param
Patch from: Pavel Roskin
As it turns out, mixing MODULE_PARM and module_param in one module is
wrong. The parameters specified in module_param are ignored. I've just
posted a patch to LKML that will detect this condition and warn about it.
The new debugging code used the new-style module_param, which means that
all instances of MODULE_PARM should be converted. The attached patch does
that.
An additional bonus is that module_param_array provides the number of
array elements. This allowed me to change tcic.c and i82365.c to use
this number for IRQ list. This change was tested with i82365. If
"irq_list" is not specified, irq_list_count is 0.
I set all permissions to 0444 to be safe. I think we have no secrets
from the users regarding those parameters. If some parameters can be
changed safely at the runtime, the permissions could be changed to 0644.
I didn't examine how safe (and how useful) it would be, so it's 0444 for
now.

[PATCH] reiserfs: fsync() speedup
From: Chris Mason <mason@suse.com>
Updates the reiserfs-logging improvements to use schedule_timeout instead of
yield when letting the transaction grow a little before forcing a commit for
fsync/O_SYNC/O_DIRECT.
Also, when one process forces a transaction to end and plans on doing the
commit (like fsync), it sets a flag on the transaction so the journal code
knows not to bother kicking the journal work queue.
queue_delayed_work is used so that if we get a bunch of tiny transactions
ended quickly, we aren't constantly kicking the work queue.
These significantly improve reiserfs performance during fsync heavy
workloads.

[PATCH] Fix bogus get_page() calls in hugepage code
From: David Gibson <david@gibson.dropbear.id.au>
Some versions of follow_huge_addr() and follow_huge_pmd() are doing a
get_page() on the target page. They shouldn't: follow_page() returns an
unpinned page and it is the caller's responsibility to pin the page (if
desired) before dropping page_table_lock.

[PATCH] ARM-related ptep_to_address() fix
From: William Lee Irwin III <wli@holomorphy.com>
rmk mentioned that ARM was borked as the relation, assumed by generic rmap,
PTRS_PER_PTE*sizeof(pte_t) == PAGE_SIZE, fails to hold. The following
patch, developed jointly with him (or depending on POV, by him with me
acting as codemonkey), is reported to resolve the issue.
Specifically, while ARM dedicates an entire PAGE_SIZE -sized block of
memory to each PTE table, the PTE table itself only spans half that, the
remainder being dedicated to hardware-interpreted structures. As the
hardware structure must be contiguous, wider ptes can't be used. So the
core-visible PTE table only spans PAGE_SIZE/2 bytes, violating the
assumption. This corrects masking and scaling done in ptep_to_address().

[PATCH] Fix vma corruption
It occurred to me that if vma and new_vma are one and the same, then
vma_relink_file will not do a good job of linking it after itself - in
that pretty unlikely case when move_page_tables fails.
And more generally, whenever copy_vma's vma_merge succeeds, we have no
guarantee that old vma comes before new_vma in the i_mmap lists, as we
need to satisfy Rajesh's point: that ordering is only guaranteed in the
newly allocated case.
We have to abandon the ordering method when/if we move from lists to
prio_trees, so this patch switches to the less glamorous use of
i_shared_sem exclusion, as in my prio_tree mremap.

[PATCH] rmap: flush_dcache revisited
From: Hugh Dickins <hugh@veritas.com>
One of the callers of flush_dcache_page is do_generic_mapping_read, where
file is read without i_sem and without page lock: concurrent truncation may
at any moment remove page from cache, NULLing ->mapping, making
flush_dcache_page liable to oops. Put result of page_mapping in a local
variable and apply mapping_mapped to that (if we were to check for NULL
within mapping_mapped, it's unclear whether to say yes or no).
parisc and arm do have other locking unsafety in their i_mmap(_shared)
searching, but that's a larger issue to be dealt with down the line.

[PATCH] rmap: swap_unplug page
From: Hugh Dickins <hugh@veritas.com>
Good example of "swapper_space considered harmful": swap_unplug_io_fn was
originally designed for calling via swapper_space.backing_dev_info; but
that way it loses track of which device is to be unplugged, so had to
unplug all swap devices. But now sync_page tests SwapCache anyway, can
call swap_unplug_io_fn with page, which leads direct to the device.
Reverted -mc4's CONFIG_SWAP=n fix, just add another NOTHING for it.
Reverted -mc3's editorial adjustments to swap_backing_dev_info and
swapper_space initializations: they document the few fields which are
actually used now, as comment above them says (sound of slapped wrist).

[PATCH] rmap: nonlinear truncation
From: Hugh Dickins <hugh@veritas.com>
The earlier changes introducing PageAnon left truncated pages mapped into
nonlinear vmas unswappable. Once we go to object-based rmap, it's
impossible to find where file page is mapped once page->mapping cleared:
switching them to anonymous is odd, and breaks strict commit accounting.
So now handle truncation of nonlinear vmas correctly. And factor in
Daniel's cluster filesystem needs while we're there: when invalidating
local cache, we do want to unmap shared pages from all mms, but we do not
want to discard private COWed modifications of those pages (which
truncation discards to satisfy the SIGBUS semantics demanded by specs).
Drew from Daniel's patch (LKML 2 Mar 04), but didn't always follow it;
fewer name changes, but still some - "unmap" rather than "invalidate".
zap_page_range is not exported, safe to give it and all the too-many layers
an extra zap_details arg, in normal cases just NULL.
Given details, zap_pte_range checks page mapping or index to skip anon or
untruncated pages. I didn't realize before implementing, that in nonlinear
case, it should set a file pte when truncating - otherwise linear pages
might appear in place of SIGBUS. I suspect this implies that ->populate
functions ought to set file ptes beyond EOF instead of failing, but haven't
changed them as yet.
To avoid making yet another copy of that ugly linear pgidx test, added
inline function linear_page_index (to pagemap.h to get PAGE_CACHE_SIZE,
though as usual things don't really work if it differs from PAGE_SIZE).
Ooh, I thought I'd removed ___add_to_page_cache last time, do so now.
unmap_page_range static, shift its hugepage check up into sole caller
unmap_vmas. Killed "killme" debug from unmap_vmas, not seen it trigger.
unmap_mapping_range is exported without restriction: I'm one of those who
believe it should be generally available. But I'm wrongly placed to decide
that, probably just sob quietly to myself if _GPL added later.

Hrm, I believe you could use this to read 128k of kernel memory.
sdla_read() takes len as a short, whereas mem.len is an int. So,
if mem.len == 0x20000, the allocation could still succeed. When cast
to short, len will be 0x0, causing the read loop to copy nothing into
the buffer. At least it's protected by a capable() check. I don't
know what proper upper bound is for this hardware, or how much it's
used/cared about. Simple memset() is trivial fix.

[PATCH] Mixed PCI/ISA device name conflicts
In systems with mixed network cards, and all drivers compiled into
the kernel; the PCI device (eth0) will get probed first, before the ISA.
The problem is that the ISA device can mistakenly try to probe

until it goes to call register_netdevice, and not all drivers have
perfect error unwind code.
This patch short circuits the device probe, so it won't bother
looking for devices that already are registered.

[PATCH] Tulip endianess fix
My tulip ethernet card doesn't work on Blue&White G3 PowerMac with Linux
2.6.5-rc2. The card is shown by lspci as
01:03.0 Ethernet controller: Linksys Network Everywhere Fast Ethernet
10/100 model NC100 (rev 11)
The kernel detects it as "ADMtek Comet rev 17".
The MAC address reported by the kernel looked obviously wrong. Also, I
could only ping the system successfully if the interface was in promiscuous
mode (running Ethereal).
Those two symptoms indicated two different problems - one for reading the
MAC address from the card on module load (tulip_init_one), and the other
for writing the address to the card when the interface was brought up
(tulip_up). I have fixed both, and here's the explanation:
tulip_init_one:
When reading the first 4 bytes of the address, inl() returns the same data
to the CPU on all platforms, interpreting the data from the lowest port
address as the least significant byte. In other words, I/O is little
endian on all platforms; it's the memory that differs across platforms.
We want to write the data to memory preserving little-endianness of the
PCI bus. To force little endian write to the memory, the data should be
converted to the little endian format.
When reading the remaining 2 bytes, the CPU gets them in 2 least
significant bytes. To write those 2 bytes to the memory in a 16-bit
operation, they should be byte-swapped for the 16-bit operation.
tulip_up:
The first 4 bytes are processed correctly, but the code is confusing.
Reading from memory needs conversion to CPU format, while writing to I/O
ports doesn't. So I replaced cpu_to_le32() to le32_to_cpu().
The second 2 bytes are read in a 16-bit memory operation, so they should
be passed to le16_to_cpu() rather than cpu_to_le32() to make them CPU
independent and suitable for outl().
All those conversions do nothing on little-endian machines, so they should
not be affected.
The patch has been tested. The driver is working fine. ping is OK, ssh
is OK, X11 over ssh is OK. Even netconsole is working fine.

[PATCH] From: David Gibson <david@gibson.dropbear.id.au>
hugepage_vma() is both misleadingly named and unnecessary. On most archs it
always returns NULL, and on IA64 the vma it returns is never used. The
function's real purpose is to determine whether the address it is passed is a
special hugepage address which must be looked up in hugepage pagetables,
rather than being looked up in the normal pagetables (which might have
specially marked hugepage PMDs or PTEs).
This patch kills off hugepage_vma() and folds the logic it really needs into
follow_huge_addr(). That now returns a (page *) if called on a special
hugepage address, and an error encoded with ERR_PTR otherwise. This also
requires tweaking the IA64 code to check that the hugepage PTE is present in
follow_huge_addr() - previously this was guaranteed, since it was only called
if the address was in an existing hugepage VMA, and hugepages are always
prefaulted.

[PATCH] ide.c: split init_hwif_default() out of init_hwif_data()
<B.Zolnierkiewicz@elka.pw.edu.pl>
[PATCH] ide_init_default_hwifs() -> ide_init_default_irq()
init_ide_data() initializes default IDE interfaces but without default IRQ
(hwif->irq and hwif->hw.irq fields) so introduce ide_init_default_irq() and
remove redundant ide_init_default_hwifs() (except arm26 and arm ones).
As a side-effect it fixes:
- CONFIG_BLK_DEV_HD_IDE if !CONFIG_BLK_DEV_IDEPCI (i386)
- hwif->noprobe shouldn't be 0 if !hwif->io_ports[IDE_DATA_OFFSET]
(alpha, i386, ia64, mips, sh, x86_64)

[PATCH] generic ide_init_hwif_ports()
Add generic ide_init_hwif_ports() to <linux/ide.h> and remove arch specific
versions except arm26, arm, h8300, i386-pc9800, m68k and m68knommu ones.

[PATCH] ppc64: siginfo conversion fix
My message queue patch fixes the 64 bits -> 32 bits conversion of
siginfo, but didn't change the 32 -> 64 bits conversion done in
sys32_rt_sigqueueinfo() which was apparently bogus as well.
After much discussion & debate on the right way of converting that
structure, I decided to go the sparc64 / s390 way, and not the x86_64
way, that is to copy the various unions data "as is". This guarantees
that whatever a 32 bist app passes there, another 32 bits app will
understand it. Crossover between 32 and 64 bits apps on such things
as home-made userland siginfo isn't something we can help with anyway.
The x86_64 choice of converting as if it was an RT signal, thus
converting the sigval, cannot easily be applied to big endian archs
since the sigval is a union of a ptr and an int, on BE, the int
happens to be on the wrong half of the 64 bits ptr, thus we can't
do a simple conversion.

[PATCH] fix for potential deadlock after posix-timers change
Ulrich has been working on the glibc code using posix-timers and
stressing it more now than it has before. He ran into an SMP deadlock
on process exit in the case there are pending queued signals from a
timer.
The deadlock arises because in the path through exit_itimers, the
tasklist_lock is already held (for writing). When a timer is being
deleted, sigqueue_free will try to take it (for reading) in the case
where that timer has a pending signal queued on somebody's queue. This
patch avoids the problem by making sure the queues are flushed before
calling exit_itimers, thus ensuring its code path won't try to take
tasklist_lock.

[PATCH] reiserfs use-after-free fix
From: Chris Mason <mason@suse.com>
reiserfs-delayed-work started using queue_delayed_work, but did not make sure
the timer was finished before it freed the work queue structs during unmount.
This leads to timer oopsen if you unmount at just the right time.

[PATCH] fix madvise(MADV_DONTNEED) for nonlinear vmas
From: Hugh Dickins <hugh@veritas.com>
Jamie points out that madvise(MADV_DONTNEED) should unmap pages from a
nonlinear area in such a way that the nonlinear offsets are preserved if the
pages do turn out to be needed later after all, instead of reverting them to
linearity: needs to pass down a zap_details block.
(But this still leaves mincore unaware of nonlinear vmas: bigger job.)

[PATCH] MIPS: don't offer SERIAL_DZ on 64-bit DEC
From: Ralf Baechle <ralf@linux-mips.org>
Limit the DZ driver to MIPS32 as the supported hardware is only present in

development).
