NFS may free the server structure without ever having used the
bdi, so we either need to flag the bdi as being uninitialized or
initialize it up front. This does the latter.This fixes a crash with mounting more than one NFS file system,
should people ever need that kind of obscure NFS functionality.Tested-by: Peter Zijlstra

Currently it just sleeps for a very short time, just 1 jiffy. If
we keep looping in there, continually delay for a little longer

Commit 5622f295 ("x86, perf_counter, bts: Optimize BTS overflow
handling") removed the regs field from struct perf_sample_data and
added a regs parameter to perf_counter_overflow(). This breaks the
build on powerpc (and Sparc) as reported by Sachin Sant:arch/powerpc/kernel/perf_counter.c: In function 'record_and_restart':
arch/powerpc/kernel/perf_counter.c:1165: error: unknown field 'regs' specified in initializerThis adjusts arch/powerpc/kernel/perf_counter.c to correspond with the

VGA arb requires DRM support for non-kms drivers, to turn on/off
irqs when disabling the mem/io regions.VGA arb requires KMS support for GPUs where we can turn off VGA
decoding. Currently we know how to do this for intel and radeon
kms drivers, which allows them to be removed from the arbiter.This patch comes from Fedora rawhide kernel.

Ingo points out that I screwed up when merging the 'timers-for-linus'
branch in commit a03fdb7612874834d6847107198712d18b5242c7.A bit too much copy-and-pasting caused the end result to have an
extraneous 'return' in the middle of an expression. That was obviously
bogus. Blush.Reported-by-with-patch: Ingo Molnar

On an AMD-64 system the processor frequency that is printed during
system boot, may be different than the tsc frequency that was
returned by the hypervisor, due to the value returned from
calibrate_cpu.For debugging timekeeping or other related issues it might be
better to get the tsc_khz value returned by the hypervisor.The patch below now prints the tsc frequency that the VMware
hypervisor returned.Signed-off-by: Alok N Kataria
