perf tools: Move syscall and arch specific defines from perf.h Into new perf-sys.h header. The main reason is to separate system specific perf data from perf tool stuff, so it could be used in small test programs, as requested Peter: http://lkml.kernel.org/r/[email protected] This separation makes the perf.h header more clear.
