Subject: [PATCH 3.16 352/366] perf tools: Move syscall number fallbacks
from perf-sys.h to tools/arch/x86/include/asm/
3.16.61-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Arnaldo Carvalho de Melo <acme@...hat.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.
