x86: change x86 to use generic find_next_bit
The versions with inline assembly are in fact slower on the machines I
tested them on (in userspace) (Athlon XP 2800+, p4-like Xeon 2.8GHz, AMD
Opteron 270). The i386-version needed a fix similar to
06024f21 to avoid
crashing the benchmark.
Benchmark using: gcc -fomit-frame-pointer -Os. For each bitmap size
1...512, for each possible bitmap with one bit set, for each possible
offset: find the position of the first bit starting at offset. If you
follow ;). Times include setup of the bitmap and checking of the
results.
Athlon Xeon Opteron 32/64bit
x86-specific: 0m3.692s 0m2.820s 0m3.196s / 0m2.480s
generic: 0m2.622s 0m1.662s 0m2.100s / 0m1.572s
If the bitmap size is not a multiple of BITS_PER_LONG, and no set
(cleared) bit is found, find_next_bit (find_next_zero_bit) returns a
value outside of the range [0, size]. The generic version always returns
exactly size. The generic version also uses unsigned long everywhere,
while the x86 versions use a mishmash of int, unsigned (int), long and
unsigned long.
Using the generic version does give a slightly bigger kernel, though.

forced by Linux to always-inline these functions via a gcc

CONFIG_OPTIMIZE_FOR_SIZE=y this can make a huge difference in
kernel image size (using a standard Fedora .config):

x86 signals: lift flags diddling code
This lifts the code diddling the TF and DF bits for signal handler setup
out of the several places copying the same code into the one place that
calls them all. There is no change in what it does.
I also separated the recently-added DF bit clearing from the TF diddling.
The compiler turns them back into one instruction anyway. The tossing
in of DF to the same line of code with no new comments was a bit more
arcane than seems wise.

x86: remove NexGen support
It is claimed that NexGen CPUs were never shipped:
http://lkml.org/lkml/2008/4/20/179
Also, the kernel support for these chips has been broken for
a long time, the code intended to support NexGen thereby being
essentially dead.
As an outcome of the discussion that can be found using the URL
above, this patch removes the NexGen support altogether.
The changes in this patch survived a defconfig build for i386, a
couple of successful randconfig builds, as well as a runtime test,
which consisted in booting a 32-bit x86 box up to the shell prompt.

x86: array can become static
In arch/x86/kernel/setup_64.c, the standard_io_resources array
is needlessly defined as global. This patch makes this variable
static.
This patch was successfully build-tested using the defconfig
for x86_64. Runtime test was performed by booting a 64-bit x86
box up to the shell prompt.

x86: remove unused function amd_init_cpu()
There are no users for the function amd_init_cpu() defined in
arch/x86/kernel/cpu/amd.c. This patch removes this routine.
This patch was build-tested using defconfigs for i386 and x86_64,
and a few randconfig instances. Runtime tests were performed by
booting 32- and 64-bit x86 boxen up to the shell prompt.

x86-64: extend MCE CPU quirk handling
At least on my Barcelona, I see MCE log entries after cold boot caused
by BIOS not properly clearing the respective registers. Therefore, this
patch extends the workaround to families 0x10 and 0x11 (the latter just
for completeness, I have nothing to verify this against).
At the same time, provide a way to make these entries visible via the
'mce=bootlog' command line option even on these machines.
