No change in functionality intended - this only adds the 32-bit side.

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.

1. make 32bit have early_init_amd_mc and amd_detect_cmp
2. seperate init_amd_k5/k6/k7 ...
v2: fix compiling for !CONFIG_SMP

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.

hard to merge by lines... (as here we have material differences between

64-bit has X86_HT set too, so use that instead of SMP.
This also removes a include/asm-x86/processor.h ifdef.

1. add c_x86_vendor into cpu_dev
2. change cpu_devs to static
3. check c_x86_vendor before put that cpu_dev into array
4. remove alignment for 64bit
5. order the sequence in cpu_devs according to link sequence...
so could put intel at first, then amd...

Krzysztof Helt found MTRR is not detected on k6-2
root cause:
we moved mtrr_bp_init() early for mtrr trimming,
and in early_detect we only read the CPU capability from cpuid,
so some cpu doesn't have that bit in cpuid.
So we need to add early_init_xxxx to preset those bit before mtrr_bp_init
for those earlier cpus.
this patch is for v2.6.27
