Merge tag 'perf-core-for-mingo-4.14-20170829' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

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

 - Fix remote HITM detection for Skylake in 'perf c2c' (Jiri Olsa)

 - Fixes for the handling of PERF_RECORD_READ records (Jiri Olsa)

 - Fix kprobes blackist symbol lookup in 'perf probe' (Li Bin)

 - The PLT header and entry sizes are not the same in !x86, fix it for ARM and
   AARCH64 (Li Bin)

 - Beautify pkey_{alloc,free,mprotect} arguments in 'perf trace' (Arnaldo Carvalho de Melo)

 - Fix CC, AR, LD external definition, allow flex and bison to be
   externally defined and other related Makefile fixes (David Carrillo-Cisneros)

 - Sync CPU features kernel ABI headers with tooling headers (Arnaldo Carvalho de Melo)

 - Fix path to PMU formats in 'perf stat' documentation (Jack Henschel)

 - Fix static build with newer toolchains (Jiri Olsa)
