Merge tag 'perf-core-for-mingo-5.5-20191203' of git://git.kernel.org/…
…pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: perf report/top: - Fix segfault due to missing initialization of recently introduced struct map_symbol 'maps' field in append_inlines(), when running with DWARF callchains. perf stat: Andi Kleen: - Affinity based optimizations for sessions with many events in machines with large core counts, avoiding excessive number of IPIs. libtraceevent: - Sudip Mukherjee: - Fix installation with O=. - Copy pkg-config file to output folder when using O=. perf bench: Arnaldo Carvalho de Melo: - Update the copies of x86's mem{cpy,set}_64.S, and because that now uses new stuff in linux/linkage.h, update that header too, which made the minimal clang version to build perf to be 3.5, as 3.4 as found in some of the container images used to test build perf can't grok STT_FUNC as a token in .type lines. ABI headers: Arnaldo Carvalho de Melo: - Sync x86's msr-index.h copy with the kernel sources, resulting in new MSRs to be usable in filter expressions in 'perf trace', such as IA32_TSX_CTRL. - Sync linux/fscrypt.h, linux/stat.h, sched.h and the kvm headers. perf trace: Arnaldo Carvalho de Melo: - Add CLEAR_SIGHAND support for clone's flags arg perf kvm: Arnaldo Carvalho de Melo: - Clarify the 'perf kvm' -i and -o command line options perf test: Ian Rogers: - Move test functionality in to a 'perf test' entry.
