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:

 * Remove die()/exit() calls from several tools.

 * Add missing perf_regs.h file to MANIFEST

 * Clean up and improve 'perf sched' performance by elliminating lots of
   needless calls to libtraceevent.

 * More patches to make perf build on Android, from Irina Tirdea

 * Resolve vdso callchains, from Jiri Olsa
