2016-07-12tools: Copy the header files needed by perf toolsArnaldo Carvalho de Melo4-0/+690
Those kernel files were being directly accessed, which we're not allowing anymore to avoid that changes in the kernel side break tooling. Warn if these copies drift from the original files.

2016-07-12perf tools: Introduce weak alternative to sched_getcpu()Arnaldo Carvalho de Melo2-0/+6
Which is just a wrapper for sys_getcpu and is not present in at least musl libc.

2016-07-12tools: Copy uapi/asm/perf_regs.h from the kernelArnaldo Carvalho de Melo1-0/+33
To allow the build to complete on older systems, where those files are either not uptodate, lacking some recent additions or not present at all. And check if the copy drifts from the kernel.

2016-07-12perf bench: Copy kernel files needed to build mem{cpy,set} x86_64 benchmarksArnaldo Carvalho de Melo5-0/+914
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.

2016-07-12perf tools: Move syscall number fallbacks from perf-sys.h to ↵Arnaldo Carvalho de Melo2-0/+18
tools/arch/x86/include/asm/ 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.

2015-05-08tools include: Add basic atomic.h implementation from the kernel sourcesArnaldo Carvalho de Melo2-0/+106
Uses the arch/x86/ kernel code for x86_64/i386, fallbacking to a gcc intrinsics implementation that has been tested in at least sparc64. Will be used for reference counting in tools/perf.

2015-05-08perf tools: Move x86 barrier.h stuff to tools/arch/x86/include/asm/barrier.hArnaldo Carvalho de Melo1-0/+28
We will need it for atomic.h, so move it from the ad-hoc tools/perf/ place to a tools/ subset of the kernel arch/ hierarchy. Other aches will follow, each in a cset.
