arch/x86/kernel/cpu/amd.c is now 100% identical to
arch/x86/kernel/cpu/amd_64.c, so use amd.c on 64-bit too
and fix up the namespace impact.

Simplify the Kconfig glue as well.

Use cpu/common.c on both 64-bit and 32-bit and remove cpu/common_64.c.

We started out with this linecount:

  816  arch/x86/kernel/cpu/common_64.c
  805  arch/x86/kernel/cpu/common.c

and the resulting common.c is 1197 lines long, so there's already
424 lines of code eliminated in this phase of the unification.

<title>x86: generate names for /proc/cpuinfo from &lt;asm/cpufeature.h&gt;</title>

<content type='text'>
We have had a number of cases where &lt;asm/cpufeature.h&gt; (and its
predecessors) have diverged substantially from the names list in
/proc/cpuinfo.  This patch generates the latter from the former.

It retains the option for explicitly overriding the strings, but by
making that require a separate action it should at least be less
likely to happen.

It would be good to do a future pass and rename strings that are
gratuituously different in the kernel (/proc/cpuinfo is a userspace
interface and must remain constant.)

<title>x86: configuration options to compile out x86 CPU support code</title>

<id>8d02c2110b3fb8e2700b31596a582a2989fd72ba</id>
<content type='text'>
This patch adds some configuration options that allow to compile out
CPU vendor-specific code in x86 kernels (in arch/x86/kernel/cpu). The
new configuration options are only visible when CONFIG_EMBEDDED is
selected, as they are mostly interesting for space savings reasons.

An example of size saving, on x86 with only Intel CPU support:

   text	   data	    bss	    dec	    hex	filename
1125479	 118760	 212992	1457231	 163c4f	vmlinux.old
1121355	 116536	 212992	1450883	 162383	vmlinux
  -4124   -2224       0   -6348   -18CC +/-

However, I'm not exactly sure that the Kconfig wording is correct with
regard to !64BIT / 64BIT.

<title>x86: move cmpxchg fallbacks to a generic place</title>

<content type='text'>
arch/x86/kernel/cpu/intel.c defines a few fallback functions
(cmpxchg_*()) that are used when the CPU doesn't support cmpxchg
and/or cmpxchg64 natively. However, while defined in an Intel-specific
file, these functions are also used for CPUs from other vendors when
they don't support cmpxchg and/or cmpxchg64. This breaks the
compilation when support for Intel CPUs is disabled.

This patch moves these functions to a new
arch/x86/kernel/cpu/cmpxchg.c file, unconditionally compiled when
X86_32 is enabled.
