Merge tag 'perf-core-for-mingo-5.3-20190709' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes: Intel PT: Adrian Hunter: - Fix DROP VIEW power_events_view in the postgresql and sqlite export-db python scripts. perf script: Song Liu: - Assume native_arch for pipe mode, fixing a segfault. perf inject: Arnaldo Carvalho de Melo: - The tool->read() call may pass a NULL evsel, handle it. core: Arnaldo Carvalho de Melo: - Move zalloc/zfree.c to tools/lib, further eroding tools/perf/util.[ch] - Use zfree() where applicable instead of open coded equivalent. - Add stdlib.h and some other headers to places where its needed and were getting via util.h, that doesn't need that anymore. - Use list_del_init() more thoroughly. Miscellaneous: Leo Yan: - Fix use after free and potential NULL pointer derefs detected by the smatch tool in various places. Luke Mujica: - Remove a couple unused variables in the parse-events code. Numfor Mbiziwo-Tiapo: - Initialize variable to suppress memory sanitizer warning in the mmap-thread-lookup 'perf test' entry.
