Our CPUID-less FPU detection code was terminally broken and, as far
as I can tell, it's been broken for a long, long time.  This series
tries to improve the situation.

Thoughts?

Andy Lutomirski (5):
  x86/cpu: Factor out application of forced cpu caps
  x86/cpu: Re-apply forced caps every time cpu caps are re-read
  x86/fpu: Fix "x86/fpu: Legacy x87 FPU detected" message
  x86/fpu: Fix CPUID-less FPU detection
  x86/fpu: Fix the "Giving up, no FPU found" test

Borislav Petkov (1):
  x86/CPU: Add X86_FEATURE_CPUID
