Merge tag 'perf-core-for-mingo' 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:

 * Handle PERF_RECORD_EXIT events in sched and annotate.

 * struct machine refactorings to help in top and trace.

 * Add on_exit implementation for systems without one, e.g. Android, from
   Bernhard Rosenkraenzer.

 * Only process events for vcpus of interest, helps handling large number
   of events, from David Ahern.

 * Cross compilation fixes for Android, from Irina Tirdea.

 * Add documentation on compiling for Android, from Irina Tirdea.

 * perf diff improvements from Jiri Olsa.

 * Target (task/user/cpu/syswide) handling improvements, from Namhyung Kim.

 * Add support in 'trace' for tracing workload given by command line, from
   Namhyung Kim.
