[PATCH 0/4] x86/fpu: Reduce unnecessary FNINIT and MXCSR usage

[Andy Lutomirski]

This series fixes two regressions: a boot failure on AMD K7 and a
performance regression on everything.

I did a double-take here -- the regressions were reported by different
people, both named Krzysztof :)

Andy Lutomirski (4):
  x86/fpu: Add kernel_fpu_begin_mask() to selectively initialize state
  x86/mmx: Use KFPU_MMX for MMX string operations
  x86/fpu: Make the EFI FPU calling convention explicit
  x86/fpu/64: Don't FNINIT in kernel_fpu_begin()
