3.16.61-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Arnaldo Carvalho de Melo acme@redhat.com
commit cec07f53c398f22576df77052c4777dc13f14962 upstream.
And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files introduced by eae7a755ee81 ("perf tools, x86: Build perf on older user-space as well").
This way we get closer to mirroring the kernel for cases where __NR_ can't be found for some include path/_GNU_SOURCE/whatever scenario.
