Yinghai Lu 11fdd252bb x86: cpu make amd.c more like amd_64.c v2 
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

Yinghai Lu e322423471 x86, cpu init: call early_init_xxx in init_xxx 
so we:

 1. could set some cap to ap
 2. restore some cap after memset in identify_cpu for boot cpu

esp for CONSTANT_TSC this matters, as:

before this patch:
 flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow rep_good nopl pni monitor cx16 lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs

after this patch:
 flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nopl pni monitor cx16 lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs

so constant_tsc is back...

Yinghai Lu 1ba76586f7 x86: cpu/common*.c have same cpu_init(), with copying and #ifdef 
hard to merge by lines... (as here we have material differences between
32-bit and 64-bit mode) - will try to do it later.

Yinghai Lu 97e4db7c87 x86: make detect_ht depend on CONFIG_X86_HT 
64-bit has X86_HT set too, so use that instead of SMP.

This also removes a include/asm-x86/processor.h ifdef.

Yinghai Lu 10a434fcb2 x86: remove cpu_vendor_dev 
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...
