perf bench mem: Sync memcpy assembly sources with the kernel

2016-10-05T22:12:46Z

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.

perf bench: Copy kernel files needed to build mem{cpy,set} x86_64 benchmarks

2016-07-12T18:20:32Z

We can't access kernel files directly from tools/, so copy the required bits, and make sure that we detect when the original files, in the kernel, gets modified.
