Ingo Molnar df6b35f409 x86/fpu: Rename i387.h to fpu/api.h
We already have fpu/types.h, move i387.h to fpu/api.h.

The file name has become a misnomer anyway: it offers generic FPU APIs,
but is not limited to i387 functionality.

Jim Kukunas 7056741fd9 lib/raid6: Add AVX2 optimized recovery functions
Optimize RAID6 recovery functions to take advantage of
the 256-bit YMM integer instructions introduced in AVX2.

The patch was tested and benchmarked before submission.
However hardware is not yet released so benchmark numbers
cannot be reported.
