Merge tag 'perf-core-for-mingo-4.20-20180924' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

Hardware tracing changes:

 intel-pt:

 - Previously, the decoder would indicate begin / end by a branch from / to zero.
   That hides useful information, in particular when a trace ends with a call.
   Remove that limitation. (Adrian Hunter)

 - Better "callindent" output in 'perf script', improving intel-PT output (Andi Kleen)

Arch specific changes:

 - Split the PMU events into meaningful functional groups for the ARM eMAG arch (Sean V Kelley)

Fixes:

 perf help:

 - Add missing subcommand `version` (Sangwon Hong)

Miscellaneous:

 - More patches renaming of structs, enums, functions to make libbtraceevent
   more generally available (Tzvetomir Stoyanov (VMware))
