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

2016-07-12T18:20:32+00:00

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.

perf bench futex: Add missing compiler.h header

2016-07-12T18:20:30+00:00

Since these files use __maybe_unused, and that is defined in
linux/compiler.h, include it.

perf bench: Disentangle headers

2016-07-12T18:19:54+00:00

We should try avoiding that perf.h header, it includes way too much
stuff, making it difficult to use things like setting _GNU_SOURCE only
on a small set of headers.
