Pulled, thanks a lot Arnaldo!
There was a merge conflict in tools/Makefile, I resolved it - please
double check I did it right.
On a related note, we still have these commits in tip:perf/x86:
a4a607086d86 perf/x86: Mark nhm_events_attrsas static
fc7d3e64651e perf/x86: Fix type to address build warning
59e1a00ac0e4 perf: Add PERF_RECORD_MISC_MMAP_DATA to RECORD_MMAP
6c538c1cc9f0 perf/x86: Add support for PEBS Precise Store
5a54b18a9e9c perf/x86: Export PEBS load latency threshold register to sysfs
66172a094e52 perf/x86: Add memory profiling via PEBS Load Latency
4b18e27234ad perf: Add generic memory sampling interface
648865900cd6 perf/core: Add weighted samples
1a4e0aca7416 perf/x86: Add flags to event constraints
5256a7d63866 perf/x86: Improve sysfs event mapping with event string
4c38cd7b6641 perf/x86: Support CPU specific sysfs events
... which merged fine originally but they now conflict with ongoing
tooling changes and are bitrotting quickly with every new perf/core
pull I do. Would be nice to resolve this problem.
Thanks,
Ingo
