Obvious inclusion of kernel.h doesn't fix it, because of circular dependencies

it seems, so just remove BUILD_BUG_ON for now.

This new color expansion acceleration for radeonfb appears to trigger
problems with X on VT switch and suspend/resume on some machines. It
might be a problem in the VT layer or in X, but I haven't quite found
it yet, so in the meantime, this disables the acceleration by default,
reverting to 2.6.27 state. It can be enabled using the "accel_cexp"

Currently audit=0 on the kernel command line does absolutely nothing.
Audit always loads and always uses its resources such as creating the

Some systems report SIS 5513 as both vendor/id and subvendor/id
string. In that case we can't distinguish the system by the id
svid/sdid and in fact the entry here breaks some boxes. At some
point we need to find another way to detect the Targa Visionary 1000,
until then this trades a hang for some users with lower performance
for others.

Since applying the fix suggested by the errata (disabling MSI), we've had
issues with interrupts being stuck on despite IIR being 0 on GM965 hardware.
Most reporters of the issue have confirmed that turning MSI back on fixes
things, and given the difficulties experienced in getting reliable MSI working
on Linux, it's believable that the errata was about software issues and not
actual hardware issues.

Revert "ide: respect current DMA setting during resume"
While 440037287c "[PATCH] switch all filesystems over to
d_obtain_alias" removed some cases where fh_to_dentry() and
fh_to_parent() could return NULL, there are still a few NULL returns
left in individual filesystems. Thus it was a mistake for that commit
to remove the handling of NULL returns in the callers.
Revert those parts of 440037287c which removed the NULL handling.
(We could, alternatively, modify all implementations to return -ESTALE
instead of NULL, but that proves to require fixing a number of
filesystems, and in some cases it's arguably more natural to return
NULL.)
Thanks to David for original patch and Linus, Christoph, and Hugh for
review.

Impact: make perfcounter NMI and IRQ sequence more robust
Make __smp_perf_counter_interrupt() a bit more conservative: first disable
all counters, then read out the status. Most invocations are because there
are real events, so there's no performance impact.
Code flow gets a bit simpler as well this way.

Implement the core kernel bits of Performance Counters subsystem.
The Linux Performance Counter subsystem provides an abstraction of
performance counter hardware capabilities. It provides per task and per
CPU counters, and it provides event capabilities on top of those.
Performance counters are accessed via special file descriptors.
There's one file descriptor per virtual counter used.
The special file descriptor is opened via the perf_counter_open()
system call:
int
perf_counter_open(u32 hw_event_type,
u32 hw_event_period,
u32 record_type,
pid_t pid,
int cpu);
The syscall returns the new fd. The fd can be used via the normal
VFS system calls: read() can be used to read the counter, fcntl()
can be used to set the blocking mode, etc.
Multiple counters can be kept open at a time, and the counters
can be poll()ed.
See more details in Documentation/perf-counters.txt.

On ARMv6 and later CPUs, it is possible for userspace processes to
get stuck on a misaligned load or store due to the "ignore fault"
setting; unlike previous CPUs, retrying the instruction without
the 'A' bit set does not always cause the load to succeed.
We have no real option but to default to fixing up alignment faults
on these CPUs, and having the CPU fix up those misaligned accesses
which it can.
