Merge tag 'perf-urgent-for-mingo-5.3-20190723' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
perf.data:
Alexey Budankov:
- Fix loading of compressed data split across adjacent records
Jiri Olsa:
- Fix buffer size setting for processing CPU topology perf.data header.
perf stat:
Jiri Olsa:
- Fix segfault for event group in repeat mode
Cong Wang:
- Always separate "stalled cycles per insn" line, it was being appended to
the "instructions" line.
perf script:
Andi Kleen:
- Fix --max-blocks man page description.
- Improve man page description of metrics.
- Fix off by one in brstackinsn IPC computation.
perf probe:
Arnaldo Carvalho de Melo:
- Avoid calling freeing routine multiple times for same pointer.
perf build:
- Do not use -Wshadow on gcc < 4.8, avoiding too strict warnings
treated as errors, breaking the build.
