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"
