Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf tooling updates from Thomas Gleixner:
"A set of perf improvements and fixes:
perf db-export:
- Improvements in how COMM details are exported to databases for post
processing and use in the sql-viewer.py UI.
- Export switch events to the database.
BPF:
- Bump rlimit(MEMLOCK) for 'perf test bpf' and 'perf trace', just
like selftests/bpf/bpf_rlimit.h do, which makes errors due to
exhaustion of this limit, which are kinda cryptic (EPERM sometimes)
less frequent.
perf version:
- Fix segfault due to missing OPT_END(), noticed on PowerPC.
perf vendor events:
- Add JSON files for IBM s/390 machine type 8561.
perf cs-etm (ARM):
- Fix two cases of error returns not bing done properly: Invalid
ERR_PTR() use and loss of propagation error codes"
