2016-10-19x86/cpufeature: Add AVX512_4VNNIW and AVX512_4FMAPS featuresPiotr Luc
AVX512_4VNNIW - Vector instructions for deep learning enhanced word variable precision. AVX512_4FMAPS - Vector instructions for deep learning floating-point single precision. These new instructions are to be used in future Intel Xeon & Xeon Phi processors. The bits 2&3 of CPUID[level:0x07, EDX] inform that new instructions are supported by a processor. The spec can be found in the Intel Software Developer Manual (SDM) or in the Instruction Set Extensions Programming Reference (ISE). Define new feature flags to enumerate the new instructions in /proc/cpuinfo accordingly to CPUID bits and add the required xsave extensions which are required for proper operation.

Commit 9a6fb28a355d ("x86/mce: Improve memcpy_mcsafe()") renames memcpy_mcsafe() to memcpy_mcsafe_unrolled(), making tools/arch/x86/lib/memcpy_64.S drift from the its kernel counterpart, triggering this warning in the perf build: Warning: tools/arch/x86/lib/memcpy_64.S differs from kernel Sync that copy to acknowledge that, no changes to 'perf bench' are needed, as this function is not used there.

Some mmap related macros have different values for different architectures. This patch introduces uapi mman.h for each architectures.
