[PATCH] blk: fix gendisk->in_flight accounting during barrier sequence
While executing barrrier sequence, the bar_rq which carries actual
write was accounted as normal IO on completion, while it wasn't on
queueing. This caused gendisk->in_flight to be decremented by 1 after
each barrier thus messed up statistics.
This patch makes bar_rq not accounted as normal IO. As the containing
barrier request as a whole is accounted, part of it shouldn't be.

[PATCH] md: fix possible oops when starting a raid0 array
This loop that sets up the hash_table has problems.
Careful examination will show that the last time through, everything but
the first line is pointless. This is because all it does is change 'cur'
and 'size' and neither of these are used after the loop. This should ring
warning bells... That last time through the loop,
size += conf->strip_zone[cur].size
can index off the end of the strip_zone array. Depending on what it finds
there, it might exit the loop cleanly, or it might spin going further and
further beyond the array until it hits an unmapped address.
This patch rearranges the code so that the last, pointless, iteration of
the loop never happens. i.e. the one statement of the last loop that is
needed is moved the the end of the previous loop - or to before the loop
starts - and the loop counter starts from 1 instead of 0.

Using asm-generic/dma-mapping.h does not work because pushing

Fix this by implementing things directly, and adding a gfp_t

Fix memory corruption caused by snmp_trap_decode:
- When snmp_trap_decode fails before the id and address are allocated,
the pointers contain random memory, but are freed by the caller
(snmp_parse_mangle).
- When snmp_trap_decode fails after allocating just the ID, it tries
to free both address and ID, but the address pointer still contains
random memory. The caller frees both ID and random memory again.
- When snmp_trap_decode fails after allocating both, it frees both,
and the callers frees both again.
The corruption can be triggered remotely when the ip_nat_snmp_basic
module is loaded and traffic on port 161 or 162 is NATed.

[PATCH] Align the node_mem_map endpoints to a MAX_ORDER boundary
Andy added code to buddy allocator which does not require the zone's
endpoints to be aligned to MAX_ORDER. An issue is that the buddy allocator
requires the node_mem_map's endpoints to be MAX_ORDER aligned. Otherwise
__page_find_buddy could compute a buddy not in node_mem_map for partial
MAX_ORDER regions at zone's endpoints. page_is_buddy will detect that
these pages at endpoints are not PG_buddy (they were zeroed out by bootmem
allocator and not part of zone). Of course the negative here is we could
waste a little memory but the positive is eliminating all the old checks
for zone boundary conditions.
SPARSEMEM won't encounter this issue because of MAX_ORDER size constraint
when SPARSEMEM is configured. ia64 VIRTUAL_MEM_MAP doesn't need the logic
either because the holes and endpoints are handled differently. This
leaves checking alloc_remap and other arches which privately allocate for
node_mem_map.

The 32 bit unsigned substraction (next - jiffies) in stop_hz_timer can
overflow if jiffies gets advanced between next_timer_interrupt and the read

[PATCH] Fix a NO_IDLE_HZ timer bug
Under certain timing conditions, a race during boot occurs where timer
ticks are being processed on remote CPUs. The remote timer ticks can
increment jiffies, and if this happens during a window when a timeout is
very close to expiring but a local tick has not yet been delivered, you can
end up with
1) No softirq pending
2) A local timer wheel which is not synced to jiffies
3) No high resolution timer active
4) A local timer which is supposed to fire before the current jiffies value.
In this circumstance, the comparison in next_timer_interrupt overflows,
because the base of the comparison for high resolution timers is jiffies,
but for the softirq timer wheel, it is relative the the current base of the
wheel (jiffies_base).

[PATCH] Cpuset: might sleep checking zones allowed fix
Fix a couple of infrequently encountered 'sleeping function called from
invalid context' in the cpuset hooks in __alloc_pages. Could sleep while
interrupts disabled.
The routine cpuset_zone_allowed() is called by code in mm/page_alloc.c
__alloc_pages() to determine if a zone is allowed in the current tasks
cpuset. This routine can sleep, for certain GFP_KERNEL allocations, if the
zone is on a memory node not allowed in the current cpuset, but might be
allowed in a parent cpuset.
But we can't sleep in __alloc_pages() if in interrupt, nor if called for a
GFP_ATOMIC request (__GFP_WAIT not set in gfp_flags).
The rule was intended to be:
Don't call cpuset_zone_allowed() if you can't sleep, unless you
pass in the __GFP_HARDWALL flag set in gfp_flag, which disables
the code that might scan up ancestor cpusets and sleep.
This rule was being violated in a couple of places, due to a bogus change
made (by myself, pj) to __alloc_pages() as part of the November 2005 effort
to cleanup its logic, and also due to a later fix to constrain which swap
daemons were awoken.
The bogus change can be seen at:
http://linux.derkeiler.com/Mailing-Lists/Kernel/2005-11/4691.html
[PATCH 01/05] mm fix __alloc_pages cpuset ALLOC_* flags
This was first noticed on a tight memory system, in code that was disabling
interrupts and doing allocation requests with __GFP_WAIT not set, which
resulted in __might_sleep() writing complaints to the log "Debug: sleeping
function called ...", when the code in cpuset_zone_allowed() tried to take
the callback_sem cpuset semaphore.
We haven't seen a system hang on this 'might_sleep' yet, but we are at
decent risk of seeing it fairly soon, especially since the additional
cpuset_zone_allowed() check was added, conditioning wakeup_kswapd(), in
March 2006.

[PATCH] NFS server subtree_check returns dubious value
Address a problem found when a Linux NFS server uses the "subtree_check"
export option.
The "subtree_check" NFS export option was designed to prohibit a client
from using a file handle for which it should not have permission. The
algorithm used is to ensure that the entire path to the file being
referenced is accessible to the user attempting to use the file handle. If
some part of the path is not accessible, then the operation is aborted and
the appropriate version of ESTALE is returned to the NFS client.
The error, ESTALE, is unfortunate in that it causes NFS clients to make
certain assumptions about the continued existence of the file. They assume
that the file no longer exists and refuse to attempt to access it again.
In this case, the file really does exist, but access was denied by the
server for a particular user.
A better error to return would be an EACCES sort of error. This would
inform the client that the particular operation that it was attempting was
not allowed, without the nasty side effects of the ESTALE error.

box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to
verify that it didn't obviously break anything. In my testing, I covered
single-card, single and dual-head setups using both HD15 and DVI-D signals,
on both the IA32 and ppc64 boxes. While everything appeared fine on both
boxes, I did encounter one problem: I can't get any signal on the DVI-D
output on the ppc64 box. However, this is also the case without my patch.
I just noticed that screen-blanking only occurs on the primary display as
well.

[PATCH] NFS: fix error handling on access_ok in compat_sys_nfsservctl
Functions compat_nfs_svc_trans, compat_nfs_clnt_trans,
compat_nfs_exp_trans, compat_nfs_getfd_trans and compat_nfs_getfs_trans,
which are called by compat_sys_nfsservctl(fs/compat.c), don't handle the
return value of access_ok properly. access_ok return 1 when the addr is
valid, and 0 when it's not, but these functions have the reversed
understanding. When the address is valid, they always return -EFAULT to
compat_sys_nfsservctl.
An example is to run /usr/sbin/rpc.nfsd(32bit program on Power5). It
doesn't function as expected. strace showes that nfsservctl returns
-EFAULT.
The patch fixes this by correcting the error handling on the return value
of access_ok in the five functions.

[PATCH] forcedeth: fix multi irq issues
With Manfred Spraul <manfred@colorfullife.com> and
Andrew Morton <akpm@osdl.org>
Bring back this recently-reverted patch, only fixed.
Original changelog:
From: Ayaz Abdulla <aabdulla@nvidia.com>
This patch fixes the issues with multiple irqs.
I am resending based on feedback. I decoupled the dma mask for
consistent memory and fixed leak with multiple irq in error path.
Thanks to Manfred for catching the spin lock problem.
Fix it:
From: Manfred Spraul <manfred@colorfullife.com>

[PATCH] sata_mv: remove local copy of queue indexes
The driver currently keeps local copies of the hardware request/response queue indexes.
But it expends significant effort ensuring consistency between the two views,
and still gets it wrong after an error or reset occurs.
This patch removes the local copies, in favour of just accessing the hardware
whenever we need them. Eventually this may need to be tweaked again for NCQ,

The 60xx chips, and possibly others, incorrectly assert DEV_IRQ interrupts

[PATCH] sata_mv: prevent unnecessary double-resets
The mv_err_intr() function is invoked from the driver's interrupt handler,
as well as from the timeout function. This patch prevents it from triggering
a one-after-the-other double reset of the controller when invoked
from the timeout function.
This also adds a check for a timeout race condition that has been observed
to occur with this driver in earlier kernels. This should not be needed,
in theory, but in practice it has caught bugs. Maybe nuke it at a later date.

If both ports are receiving on the SysKonnect dual port cards,
then it appears the bus interface unit can give an interrupt status
for frame before DMA has completed. This leads to bogus frames

messed up on dual port cards.
A workaround for the out of order receive problem is to eliminating
split transactions on PCI-X.
