Merge tag 'perf-urgent-for-mingo-5.7-20200414' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgentperf-urgent-2020-04-19

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

perf stat:

  Jin Yao:

  - Fix no metric header if --per-socket and --metric-only set

build system:

  - Fix python building when built with clang, that was failing if the clang
    version doesn't support -fno-semantic-interposition.

tools UAPI headers:

  Arnaldo Carvalho de Melo:

  - Update various copies of kernel headers, some ended up automatically
    updating build-time generated tables to enable tools such as 'perf trace'
    to decode syscalls and tracepoints arguments.

    Now the tools/perf build is free of UAPI drift warnings.
