Subject: [PATCH -tip] x86: cpu/proc.c grouping of cpuid in /proc/cpuinfo

Unification of cpuid_level.
Also added extended_cpuid_level to make it complete.

So cpuid* and cpufeature flag come in same group and /proc/cpuinfo
looks like on AMD box:

cpuid level     : 1
ext cpuid level : 0x8000001a
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 rdtscp lm 3dnowext 3dnow constant_tsc rep_good nonstop_tsc pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch osvw skinit
