2016-09-21	lib/raid6: Add AVX512 optimized gen_syndrome functions	Gayatri Kammela	1	-0/+10
	Optimize RAID6 gen_syndrom functions to take advantage of the 512-bit ZMM integer instructions introduced in AVX512. AVX512 optimized gen_syndrom functions, which is simply based on avx2.c written by Yuanhan Liu and sse2.c written by hpa. The patch was tested and benchmarked before submission on a hardware that has AVX512 flags to support such instructions Cc: H.

2015-05-19	x86/fpu: Rename i387.h to fpu/api.h	Ingo Molnar	1	-1/+1
	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.

2012-12-13	lib/raid6: Add AVX2 optimized recovery functions	Jim Kukunas	1	-5/+9
	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. Acked-by: "H.
