SubjectRe: [PATCH -tip] x86: cpu_debug.c prepare report if files are inappropriate or CPU is not supported

hm, on a second look - the whole cpu_model / cpu_modelflag
business in arch/x86/kernel/cpu/cpu_debug.c looks
over-complicated and broken. You encode it into a
'modelflag':

per_cpu(cpu_model, cpu) = ((cpui->x86_vendor << 16) |
(cpui->x86 << 8) |
(cpui->x86_model));

just to decode it later on:

flag = per_cpu(cpu_model, cpu);

switch (flag >> 16) {

That does not make much sense. Please use a proper
boot_cpu_data.x86_vendor switch() statement, ok?
