Hi,

so this is the final result. Patches boot on every qemu cpu model and on
two baremetal configs here.

The three patches after yours are some small fixlets for issues I
spotted while testing.

Thanks.

Borislav Petkov (3):
  x86: Fold-in trivial check_config function
  x86, AMD: Correct {rd,wr}msr_amd_safe warnings
  x86, CPU, AMD: Drop useless label

Right,

here's the fixed version which boots fine on everything I have here.
It would be nice if Ingo could test it on his K8 with the 32-bit
MATH_EMULATION config to make sure the corruptions don't happen anymore.

The second one is the sanity check for static_cpu_has which we discussed
yesterday.

And how cool is that: it already caught an unrelated issue in the FPU
code which resulted in patch #3. Fun.

Thanks.
