<dtor_core@ameritech.net>
Patch from Sau Dan Lee
Input: i8042 - kill the timer only after removing interrupt handler,
otherwise there is a chance that interrupt handler will install
the timer again and it will trigger after module is unloaded.
<dtor_core@ameritech.net>
Input: mousedev - better multiplex absolute and relative devices;
cleanups
<davej@redhat.com>
[AGPGART] Various Intel/EM64T AGP fixes.
From Andi Kleen.
- Add full PCI IDs to the module table for intel-agp and intel-mch-agp.
Don't use PCI_ANY_ID for device, since the drivers cannot handle unknown
devices anyways.
This fixes the problems with them loading both when compiled in and
also helps external tools that use the module PCI table to find the
correct driver.
- Remove wrong hack in intel-mch-agp that checked for long mode.
EM64T capability has nothing to do with the MCH version.
To avoid double probing the fix above is better.
- Handle the case of no AGP capability (unlikely, but better to handle it)
<async@cc.gatech.edu>
evdev.c:
input: Fix an oops at opentime of /dev/input/event devices
<vojtech@suse.cz>
input: Check for IM Explorer mice even if IMPS check failed.
<tiwai@suse.de>
input: Fix oops in hiddev
<davej@redhat.com>
[AGPGART] Don't abort if Intel-agp can't find AGP capability.
Some bridges don't have this set it seems.
Detective work, and fixing by Andi Kleen.
<aia21@cantab.net>
NTFS: Add a new address space operations struct, ntfs_mst_aops, for mst
protected attributes. This is because the default ntfs_aops do not
make sense with mst protected data and were they to write anything to
such an attribute they would cause data corruption so we provide
ntfs_mst_aops which does not have any write related operations set.
<davej@redhat.com>
[AGPGART] Make the driver only announce the PCI IDs it actually supports.
This avoids dups with the amd64 driver.
From: Andi Kleen

<davej@redhat.com>
[AGPGART] Remove lots of trailing whitespace from amd64 gart driver.
No code changes.
<davej@redhat.com>
[AGPGART] Fix a potential leak in intel driver.
It's not leaking anything currently, as agp_alloc_bridge() doesn't do any
actual allocations right now, but if/when things get changed to support
multiple bridges, these error paths need to free up the allocation.
<davej@redhat.com>
[CPUFREQ] Silence noisy debugging printk in longhaul driver.
<davej@redhat.com>
[CPUFREQ] Convert longhaul driver to use module_param
<davej@redhat.com>
[CPUFREQ] Remove some unneeded includes.
<davej@redhat.com>
[CPUFREQ] Use correct printk prefix in p4-clockmod driver
<davej@redhat.com>
[CPUFREQ] Quieten the powernow-k7 init printk a little.
There seem to be quite a few desktop K7 processors which support the
powernow cpuid call, but don't actually offer any powernow scaling.
In which case the driver prints out
"PowerNOW! Technology present. Can scale: nothing" which looks a bit odd,
and just adds to confusion of end-users.
Change things so that we don't print anything at all if we can't do anything.
Also kill some trailing whitespace gremlins that crept in.
<davej@redhat.com>
[CPUFREQ] Remove a bunch of trailing whitespace from the powernow-k8 driver.
<davej@redhat.com>
[CPUFREQ] Fix leak in powernow-k8
Spotted by Yury Umanets
<davej@redhat.com>
[CPUFREQ] Make longhaul debug a module option.
<davej@redhat.com>
[CPUFREQ] Scaling on VIA C3 Nehemiah works now.
So remove the warning printk.
<aia21@cantab.net>
NTFS: Cleanup dirty ntfs inode handling (fs/ntfs/inode.[hc]) which also
includes an adapted ntfs_commit_inode() and an implementation of
ntfs_write_inode() which for now just cleans dirty inodes without
writing them (it does emit a warning that this is happening).
<aia21@cantab.net>
NTFS: 2.1.12 release - Fix the second fix to the decompression engine.
<davej@redhat.com>
[CPUFREQ] fix panic in powernow_k8_verify on MP but PSB systems.
Instead of -ENODEV; powernow_k8_cpu_init returns 0 if it's running on a MP
system but PSB BIOS is tried... this causes a panic in
powernow_k8_verify, as can be seen at

[AGPGART] SIS AGP updates
Signed-off-by: Dave Jones <davej@redhat.com>
From: "Heilmann, Oliver" <Oliver.Heilmann@drkw.com>
* renamed sis_648_enable to sis_delayed_enable and removed chipset
references
* All chipsets that require the sis delay-hack are listed in
sis_broken_chipsets (and no other place).
* There are two new module options to force agp3-spec compliant
initialisation and/or the delay hack. As I only have a 648FX chipset to
test on, I figured this might be useful to experiment with on other
chipsets (i.e.746[FX]).
Basically, if you have an SiS chipset and your machine freezes when you
start X, try the -agp_sis_force_delay=1 option. If this fixes your
problem add your PCI ID to sis_broken_chipsets in sis-agp.c
Note to 746[FX] people: I'm still not sure what the differences between
the two 746 versions and the 648 series are. If this patch does not work
for you try playing with the agp_sis_agp_spec module option. Any
feedback is greatly appreciated.

ia64: Reserve syscall # for vserver().
<bjorn.helgaas@hp.com>
[PATCH] ia64: fix hotplug config placement
HOTPLUG_CPU depends on SMP, so why not put it under SMP?
<jgarzik@redhat.com>
[netdrvr e1000] use generic ethtool_ops provided in net/core/ethtool.c
<jbarnes@engr.sgi.com>
[PATCH] ia64: don't udelay() in sn_mmiob
sn_mmiob is a lightweight way to ensure PCI write ordering, intended
to be used as an alternative to doing a PIO read. Unfortunately, with
the udelay() in there, it ends up being slower than a PCI read on
small configurations, so remove it in favor of a simple cpu_relax().
<jgarzik@redhat.com>
[netdrvr 8139too] remove bogus config option test
8139too should not be testing CONFIG_EMBEDDED.
Thanks to Christoph Hellwig for pointing this out.

sparse to warn about implicit typing.
<ak@suse.de>
[PATCH] x86-64 update
Add accumulated bug fixes for x86-64 and some minor cleanups.
- Add ptep_set_access_flags from i386
- Change memory text mapping to 10MB from 40MB to make alias window
smaller
- Disable change_page_attr for kernel mapoing for now (wrong, but the
other code also doesn't work)
- Add .bss.page_aligned and align interrupt/exception stacks (idea from
Matt Mackall)
- Protect sysenter MSR setup against missing registers.
- Set mce tolerance level to 1 (panic instead of deadlock)
- Fix cross 4GB bug in find_first_bit (Michael Matz)
- Add missing memory clobbers in bitops.h (Suresh B. Siddha)
- Check kernel size at boot up
- Set boot cpu online at boot to fix early printk
- Fix EFER bit definitions (Dave Jones)
- Fix comments in 32bit syscall table.
- Quieten all 32bit syscalls that are unimplemented in 32bit.
- Various MCE fixes suggested by Eric Morton, David Boles et.al.
More to come.
- Quieten some printks
- Fix cpu online check in msr driver
- Lower polling interval for machine checks to 5 minutes to avoid
overrunning the registers.
- Make memcpy_{from,to}io more compatible with i386 (Roland Dreier)
<ak@suse.de>
[PATCH] Really fix empty node 0 on x86-64
x86-64 shares some numa code with i386, and that didn't handle holes in
the node map properly. Fix this.
<torvalds@ppc970.osdl.org>
ppc64: use "ASM_CONST()" to give proper C type to constants
that can also be used in assembly language context.
This one fixes the common CPU_FTR_COHERENT_ICACHE warning in
asm/cacheflush.h.

[PATCH] Fix compilation on x86-64
I managed to break compilation with my last patch with a last minute edit.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: missed setsockopt wrappers
Here's the tail of setsockopt I've missed - for old protocol families we
have wrappers around those methods.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: dev_ioctl() callers
dev_ioctl() has a __user pointer argument; however, its declaration
lacks that and callers are also wrong. Declaration fixed, callers updated.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: missed piece of sock_get_timestamp() annotation
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: trivial part of net/* annotation

several bits that fell out of previous patch (trivial annotations)
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: net/* non-ANSI argument lists
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: amd64 annotation - beginning
Annotated basic primitives (copy_.._user, get_user, ...).
Functions got __user in prototypes, macros (in uaccess.h) got a
conditional check - see CHECK_UPTR() below. If you have more elegant
way to deal with the macros - please, tell.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: amd64 annotations - trivial part

[PATCH] sparse: tty_ioctl annotation
tty_ioctl.c annotation
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: vt and friends
vt, vt_ioctl, consolemap and selection annotated, struct unimapdesc
and struct consolefontdesc got __user on their pointer members.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: n_tty annotation
n_tty annotated, ldisc_struct ->read() and ->write() got __user
on their buf argument.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: tty_driver ->write_proc()
Made ->write_proc in tty_driver suitable for procfs write callback
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: SIOCGIFCONF handling - the rest of it
Fixed the type of SIOCGIFCONF callback; inet instance was already
correctly annotated, decnet one was _not_. Moreover, decnet callback
needed fixing - dereferencing userland address.
<torvalds@ppc970.osdl.org>
ppc64: more explicitly typed constants
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse alpha: beginning of __user annotation

<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse alpha: #if abuses
#if where #ifdef should've been
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse alpha: trivial parts of __user annotation
Trivial stuff in arch/alpha annotated; in two cases of
osf_proplist_syscall() dereferencing userland pointers replaced with
get_user
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse alpha: utimes()
... and that's where I'd found do_utimes() crap before I went
grepping ;-)
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse alpha: the rest of it
A bunch of "return in void function" dealt with, removed bogus extern
from definition of __load_new_mm_context(), sanitized fscking ugly
CROSS_64K() helper (even if sparse doesn't segfault on that anymore,
it's _still_ fscking ugly).
<torvalds@ppc970.osdl.org>
ppc64: mark the "regshere" marker with proper type information.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] trivial annotation for arch/i386/kernel/*
Several places in arch/i386/kernel were still un-annotated - they didn't
trip copy_.._user(), so they stayed alive. Caught and killed.
That's not all - there's a big cluster of them in vm86.c, but I haven't
looked into that code yet.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: reiserfs annotation
Everything straigthforward and takes care of almost all sparse warnings
in fs/reiserfs/*.
<rmk@flint.arm.linux.org.uk>
[PCMCIA] Fix up SOC PCMCIA socket timing calculations
The timing calculations used by the PXA platforms did not always take
account of the timings handed to us by PCMCIA, and where it did, it
assumed IO timings for memory windows.
We fix this, and provide a generic function which calculates the
required timings (in nanoseconds) for IO, memory and attribute
windows. The SOC drivers only have to convert this information to
whatever format the hardware requires to achieve at least these
timing parameters.
<rmk@flint.arm.linux.org.uk>
[ARM] Eliminate meminfo 'end' element
Some machines decided to initialise this element. It's not necessary
since find_memend_and_nodes() initialises this itself. However,
'end' is not required if we initialise high_memory in this function
rather than waiting until mem_init() is called.

<torvalds@ppc970.osdl.org>
sparse: add "__force" type attribute for forcing a cast.
<torvalds@ppc970.osdl.org>
ppc64: check more of the user access functions for proper arguments.
<torvalds@ppc970.osdl.org>
ppc64: missing __user annotations noticed by stricter checks.
<torvalds@ppc970.osdl.org>
sparse: make x86 user pointer checks stricter.
Also use "__force" when forcing the user address to "unsigned long"
for the address limit check.
<marcel@holtmann.org>
[Bluetooth] Move function exports out of syms.c
With Linux 2.6 there is no need to keep the function exports in a

[SPARC64]: __volatile --> __volatile__
<petero2@telia.com>
[PATCH] Avoid excessive stack usage in NFS
Assigning '*wdata' with a dynamic initializer creates a
temporary structure copy on the stack, and then the final
data is initialized with a "memcpy()".
As a result, these NFS functions use more than 800 bytes
of stack-space.
Changing the code to just do a memset followed by explicit
initialization of the non-zero member variables takes the
stack usage down to 36 bytes.
Here is a patch that does exactly that.

[PATCH] Improve `make checkstack'
On i386, stack usually grows with "sub $0x8,%esp" and shrinks with
"add $0x8,%esp" respectively. In some cases, though, stack grows with
"add $0xffffff80,%esp" and shrinks with "sub $0xffffff80,%esp".
Obviously, we don't want to miss those cases.
Since in either case add and sub seem to be balanced and contain the
same parameter, we don't need a second regex. We simply accept hex
numbers of up to 8 digits and treat them as negative numbers when the
sub appears to be a little too high.
...or so I thought. But another day of testing proved me wrong again.
Some functions do stuff like "sub $0x10,%esp", ..., "add $0x20,%esp".
In other words, add and sub are *NOT* balanced. Manual inspection
showed that 0x20 is a more realistic number, so I accept either
variant, just in case. We pay for this with a bunch of duplicates in
our output, but that beats missing some stack hogs.
In the long run, this script has to be replaced by gcc options,
really. Looking at the result and guessing back is such a stupid
idea.

[PATCH] ppc64: fix missing RELOCs, add linux,phandle property
This fixes a couple of bugs in arch/ppc64/kernel/prom.c. We were
missing a couple of places where we needed to use RELOC(). I added the
RELOC in one case, and in the other, moved the variable that we were
accessing onto the stack (and reduced its size). (We use the variable
to get a property value, but we aren't interested in the value, just in
whether the property exists or not. Since we pass the size of the
variable to the OF getprop call, it won't overflow.) The effect of
missing the RELOCs would be that random memory locations get used on IBM
pSeries systems (possibly causing random boot failures).
The other thing that this does is add a linux,phandle property to each
node, containing the phandle for the node, which is the token that OF
uses to identify the node. Some nodes reference other nodes by means
of their phandle. Without the linux,phandle property, userspace code
looking at the OF device-tree image in /proc/device-tree has no way of
knowing which other node is being referenced.

[PATCH] Add FUTEX_CMP_REQUEUE futex op
From: Jakub Jelinek <jakub@redhat.com>
FUTEX_REQUEUE operation has been added to the kernel mainly to improve
pthread_cond_broadcast which previously used FUTEX_WAKE INT_MAX op.
pthread_cond_broadcast releases internal condvar mutex before FUTEX_REQUEUE
operation, as otherwise the woken up thread most likely immediately sleeps
again on the internal condvar mutex until the broadcasting thread releases
it.
Unfortunately this is racy and causes e.g.
http://sources.redhat.com/cgi-bin/cvsweb.cgi.../cvsroot=glibc
to hang on SMP.
http://listman.redhat.com/archives/phil-list/2004-May/msg00023.html contains
analysis how the hang happens, the problem is if any thread does
pthread_cond_*wait in between releasing of the internal condvar mutex and
FUTEX_REQUEUE operation, a wrong thread might be awaken (and immediately go
to
sleep again because it doesn't satisfy conditions for returning from
pthread_cond_*wait) while the right thread requeued on the associated mutex
and there would be nobody to wake that thread up.
The patch below extends FUTEX_REQUEUE operation with something FUTEX_WAIT
already uses:
FUTEX_CMP_REQUEUE is passed an additional argument which is the expected
value
of *futex. Kernel then while holding the futex locks checks if *futex !=
expected and returns -EAGAIN in that case, while if it is equal, continues
with a normal FUTEX_REQUEUE operation. If the syscall returns -EAGAIN, NPTL
can fall back to FUTEX_WAKE INT_MAX operation which doesn't have this
problem,
but is less efficient, while in the likely case that nobody hit the (small)
window the efficient FUTEX_REQUEUE operation is used.

[PATCH] active_load_balance() deadlock
active_load_balance() looks susceptible to deadlock when busiest==rq.
Without the following patch, my 128-way box deadlocks consistently
during boot-time driver init.
<torvalds@ppc970.osdl.org>
Add comments on load balancing special cases.
Ingo explains:
The condition is 'impossible', but the whole balancing code is
(intentionally) a bit racy:
cpus_and(tmp, group->cpumask, cpu_online_map);
if (!cpus_weight(tmp))
goto next_group;
for_each_cpu_mask(i, tmp) {
if (!idle_cpu(i))
goto next_group;
push_cpu = i;
}
rq = cpu_rq(push_cpu);
double_lock_balance(busiest, rq);
move_tasks(rq, push_cpu, busiest, 1, sd, IDLE);
in the for_each_cpu_mask() loop we specifically check for each CPU in
the target group to be idle - so push_cpu's runqueue == busiest [==
current runqueue] cannot be true because the current CPU is not idle, we
are running in the migration thread ... But this is not a real problem,
load-balancing we do in a racy way to reduce overhead [and it's all
statistics anyway so absolute accuracy is impossible], and active
balancing itself is somewhat racy due to the migration-thread wakeup
(and the active_balance flag) going outside the runqueue locks [for
similar reasons].
so it all looks quite plausible - the normal SMP boxes dont trigger it,
but Bjorn's 128-CPU setup with a non-trivial domain hiearachy triggers
it.

Revert CONFIG_NET_GIGE change.
The proper fix is _not_ NET_ETHERNET or default twiddling,
but better overall organization of the ethernet driver selection,
which would include not only CONFIG_NET_GIGE but other options as well.
Reverted back to old behavior until a full and complete solution
appears (and people like it, of course).

This patch is what we want. We don't in fact need to do the read

However, we need to do it in ppp_synctty.c as well as ppp_async.c.

[libata promise] revert broken taskfile delivery change

this change was not needed, but Promise executes commands differently

[PATCH] ramfs o_sync oops fix
Writing to ramfs files with O_SYNC dereferences null in mpage_writepages(),

->generic_osync_inode
->write_inode_now
->__writeback_single_inode
->__sync_single_inode

The best fix for this is to visit all ram-backed filesystems and give them a
no-op a_ops.writepages. But baling out if the file is memory-backed is a
sufficient coverall and is how we handle this in __filemap_fdatawrite().

[PATCH] shrink_all_memory() fixes
- Off-by-one in balance_pgdat means that we're not scanning the zones all
the way down to priority=0.
- Always set zone->temp_priority in shrink_caches(). I'm not sure why I had
the `if (zone->free_pages < zone->pages_high)' test in there, but it's
preventing us from setting ->prev_priority correctly on the
try_to_free_pages() path.
- Set zone->prev_priority to the current priority if it's currently a
"lower" priority. This allows us to build up the pressure on mapped pages
on the first scanning pass rather than only on successive passes.

On some systems it can take a hotplugged cpu much longer to come up than it

die in its first attempt to kmem_cache_alloc (uninitialized percpu data, I
imagine).

to become available; the patch waits five seconds just to be safe.

[PATCH] partition table validity checking
From: Andries Brouwer <Andries.Brouwer@cwi.nl>
The patch examines a putative partition table, and if that doesnt look like a
valid partition table it goes away again.
Some devices have partition tables (and there are many styles of such), some
don't. Traditionally fixed disks have one, floppies don't. Nobody knows
what
happens with ZIP disks, USB sticks and other such things. Both the DOS-type
partition table, and the "big floppy" whole disk FAT filesystem are common.
It is undesirable for the kernel to detect partitions where there are none.
This leads to great confusion, sometimes to kernel crashes.
In the particular case of DOS-type partition tables a partition entry has a
1-byte field boot_ind that traditionally is 0x80 for the boot partition and 0
for the other three primary partitions. Linux does not use this field, and
one sometimes sees tables with all four entries zero.
The patch tells the kernel not to think that something is a valid DOS-type
partition table when a value other than 0 or 0x80 is encountered. I think it
is a fairly safe change: I do not know of any fdisk-type program that will
write other values there.

From: Jack Steiner <steiner@sgi.com>
It looks like the call to sched_balance_exec() from do_execve() is in the

"filename" actually exists.
In many cases, users have several entries in $PATH. If a full path name is
not specified on the 'exec" call, the library code iterates thru the files
in the PATH list until it finds the program. This can result is numerous
migrations of the parent process before the program is actually found.

[PATCH] bug in sys_io_setup
From: Jerzy Szczepkowski <js189202@zodiac.mimuw.edu.pl>
There is a bug in sys_io_setup().
If ioctx_alloc() succeeds and put_user() fails io_destroy() is called.
io_destroy() assumes that ioctx->users >= 2 (if context is alive) and calls
put_ioctx twice, while in this sequence ioctx->users == 1.

[PATCH] direct-io invalidation fix
clean_blockdev_aliases() is using the wrong thing to work out how many
filesystem blocks should be invalidated. It invalidates too many, which can
cause live fs metadata buffers to be invalidated when they are pending
writeout. It's a filesystem-wrecker, although seems very hard to hit.

[PATCH] ppc32: Add _raw_write_trylock
I tried compiling a PPC32 kernel with PREEMPT + SMP and it failed
because we didn't have a _raw_write_trylock. This patch adds
_raw_write_trylock, moves the exports of _raw_*lock from
arch/ppc/kernel/ppc_ksyms.c to arch/ppc/lib/locks.c, and makes
__spin_trylock static since it is only used in locks.c.

[PATCH] ppc32: Suppress bogus info in /proc/ppc_htab on 64-bit cpus
In the ppc32 kernel, we have a /proc/ppc_htab file that trawls through
the MMU hash table and prints various statistics on it such as percent
occupancy. However, the hash table entry format is different on
64-bit cpus (POWER3, G5) which the ppc32 kernel does support (in
32-bit mode).
This patch disables the scanning of the MMU hash table and printing of
the statistics that we get from it on 64-bit cpus. Since the
statistics are only for interest, and the ppc32 kernel is being used
less and less on 64-bit cpus now that the ppc64 kernel is in
reasonable shape, I didn't think it worth while to add code to deal
with the 64-bit HPTE format.

[PATCH] ppc32: Use -fPIC instead of -mrelocatable-lib
The ppc32 boot code has a couple of files that are executed very early
on before the kernel is mapped at the address it is linked at. We
have been using -mrelocatable-lib to compile these files, but
apparently -mrelocatable-lib is deprecated and the gcc developers are
threatening to remove it. In fact the -fPIC flag does what we need.
This patch changes -mrelocatable-lib to -fPIC.

[PATCH] ppc32: Make ppc32 PCI code more robust
The main thrust of this patch is to make the ppc32 PCI code more
robust by checking for bus->resource[] being NULL before using it. We
can legitimately get elements of bus->resource being NULL and I have
actually hit that on some machines. This patch also allows resources
starting at 0 to be accepted as assigned (we can and do get PCI
resources starting at 0 in I/O space on PPC machines) and provides a
sensible default for the case where Open Firmware doesn't give us a
bus-range property for a PCI bridge.

The tricky part here was an iterator that used to take a callback and

thing is, two callbacks expect (and get) char __user * while other two
expect (and also get) char __user **.
Iterator used to use void * as "opaque data"; I've switched it to
unsigned long. Note that there was nothing that said "it's a pointer" -
use of callback that would take e.g. int is also perfectly legitimate.

[NETFILTER]: Fix checksum bug for multicast/broadcast packets on postrouting
hook.
In a nutshell, skb checksum mangling has been removed from
nf_hook_slow() and pushed up to whatever really needs to do it.
Namely: NAT, ip_fw_compat, ipt_TCPMSS, IPSec transforms.
skb_checksum_help() has been changed to perform an skb_copy() if needed
(e.g. the original problem case where bcast/mcast was cloning packets for
transmission over loopback, changing ip_summed).
Because of the above, the output path has been modified to take into
account the fact that an skb may need to be changed in some places. There
are some minor changes in the routing code to take care of the now
different input and output function prototypes. The ipv6 fragmentation
code has been modified to detect a changed skb.
The rest of the patch (probably the bulk of it) is simply the result of
changing to double skb pointers.
I've tested this with ipv4, ipv6, ipsec (including xfrm bundles), NAT and
the original DHCP test case. Everything seems to be working ok.

arch/arm/mm/mmap.c: arch_get_unamapped_area() checks bit 9 in the cache type
register for possible cache aliasing problems. Bit 11 should be checked

[PATCH] sparse: if_mii() helper (from jgarzik)
From: Jeff Garzik
Jeff's patch adds a helper for obtaining mii_ioctl_data from ifreq
and switches drivers to it. It's almost a "move common expression into
inline helper", except that instead of
(struct mii_ioctl_data *)&rq->ifr_ifru.ifru_data
it does
(struct mii_ioctl_data *)&rq->ifr_ifru
- pointer to union instead of pointer to a field of union that has nothing
to do with mii_ioctl_data *and* adds confusion by being a pointer itself.
<viro@parcelfarce.linux.theplanet.co.uk>
[PATCH] sparse: the rest of ifr_data cleanups and annotations
The rest of ->ifr_data cleanups. A bunch of drivers use address
of ifr->ifr_ifru, but spell that as &ifr->ifr_data, which expands to
&ifr->ifr_ifru.ifru_data. ifr_ifru is a union and in effect they sneak in
a private field into that union; ifr_ifru.ifru_data is a field in that
union and it has nothing to do with the things they want to do. Cleaned
up by explicit use of &ifr->ifr_ifru.
Several places where we really use ->ifr_data (i.e. use its value
and use it as __user pointer) annotated.

In latest linux-2.5 bitkeeper, if you turn on CONFIG_HOTPLUG_CPU w/

ia64: work around linker bug
Building 2.6.6-ia64-040521, using GNU ld version 2.14.90.0.4 20030523.
__gp is sometimes set incorrectly. Instead of being .got + 0x2000000,
it is set to .data + 0x2000000, which breaks some LTOFF22 and GPREL22
entries.
This is non-deterministic, changing the path name to the kernel tree
which changes the size of some messages in .data is enough to make the
linker get it right. Force __gp to be based on .got.
HJ Lu says this is fixed in newer versions of binutils but the work around
is sensible enough that it is a better solution than forcing everybody
to upgrade binutils.

[PATCH] mm: vma_adjust insert file earlier
For those arches (arm and parisc) which use the i_mmap tree to implement
flush_dcache_page, during split_vma there's a small window in vma_adjust when
flush_dcache_mmap_lock is dropped, and pages in the split-off part of the vma
might for an instant be invisible to __flush_dcache_page.
Though we're more solid there than ever before, I guess it's a bad idea to
leave that window: so (with regret, it was structurally nicer before) take
__vma_link_file (and vma_prio_tree_init) out of __vma_link.
vma_prio_tree_init (which NULLs a few fields) is actually only needed when
copying a vma, not when a new one has just been memset to 0.
__insert_vm_struct is used by nothing but vma_adjust's split_vma case:
comment it accordingly, remove its mark_mm_hugetlb (it can never create
a new kind of vma) and its validate_mm (another follows immediately).

[PATCH] mm: get_user_pages vs. try_to_unmap
Andrea Arcangeli's fix to an ironic weakness with get_user_pages.
try_to_unmap_one must check page_count against page->mapcount before
unmapping
a swapcache page: because the raised pagecount by which get_user_pages
ensures
the page cannot be freed, will cause any write fault to see that page as not
exclusively owned, and therefore a copy page will be substituted for it - the
reverse of what's intended.
rmap.c was entirely free of such page_count heuristics before, I tried hard
to
avoid putting this in. But Andrea's fix rarely gives a false positive; and
although it might be nicer to change exclusive_swap_page etc. to rely on
page->mapcount instead, it seems likely that we'll want to get rid of
page->mapcount later, so better not to entrench its use.

[PATCH] ext3: htree rename fix
A problem with htree was recently discovered during Lustre testing when
files were being renamed within the same directory. In some cases the
addition of the new name caused a directory block split and the old
dir_entry was pointing at the wrong entry, and the wrong entry was removed.
This would seem entirely possible in a Maildir directory, since the MTA
will be doing a lot of renames within the same directory.
If old_de is pointing to the newly-added entry (i_ino is the same) we end up
deleting the new entry instead of the old one. It looks as if the rename
never happened. We need to verify that the name we are unlinking is what we
expect.
If is also possible that old_de is pointing to the now-unused space at the
end
of a newly-split leaf block, so we still need to try ext3_delete_entry()
(which will skip the stale entry and return ENOENT) instead of just relying
on
the inum + name check.

entry into the cache meant that this could happen even when rsc_lookup is
called with set == 0.
Note that the ip_map code has the same bug, not that it seems to matter much,
since the memory in question in that case is always just a statically
allocated string.

a
real likelyhood that something needs doing. So the test at the top must

But it didn't cover the possibility that the last outstanding request on a

As a result, a failed drive might not get removed from the personalities
perspective on the array, and so it could never be removed from the array as
a
whole.

MD_RECOVERY_NEEDED is set so that md_check_recovery will do stuff.
