Subject: [PATCH 0/3] x86/CPUID: CPUID parsing rework, p1

From: Borislav Petkov <bp@...e.de>

Hi all,

this is the beginning of a long conversion. The final goal is to have
one global, read-only CPUID hierarchy representation in arch/x86/ to
replace all the gazillion places where CPUID is read and thus slim a lot
of code. And improve all that X86_FEATURE* diddling. We'll see...

Anyway, these are the first three patches slimming cpuinfo_x86 by
80 bytes per CPU, by making vendor ID and brand name global and
__ro_after_init.

Comments, reviews, etc are welcome, as always.

Thx.

  x86/cpuid: Make cpuinfo_x86.x86_vendor_id global
  x86/cpuid: Get vendor ID on the BSP
  x86/cpuid: Make cpuinfo_x86.x86_model_id global
