Subject[PATCH 0/4] x86/fpu: Reduce unnecessary FNINIT and MXCSR usage
Date
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()
