Merge tag 'perf-core-for-mingo-5.0-20190110' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/urgent

Pull perf/core fixes and improvements from Arnaldo Carvalho de Melo:

perf trace:

  Ravi Bangoria:

  - Rework PowerPC syscall table generation, now using a .tbl file just like
    x86_64 and S/390, also silencing a tools build warning about headers out of
    sync with the kernel sources.

tools include uapi:

  Arnaldo Carvalho de Melo:

  - Sync linux/if_link.h copy with the kernel sources, silencing a build warning.

perf top:

  Arnaldo Carvalho de Melo:

  - Add 'arch_cpu_idle' to the list of kernel idle symbols, noticed on a Orange
    Pi Zero ARM board, just like with other symbols in other arches.
