Merge tag 'perf-core-for-mingo' of... 

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 from Arnaldo Carvalho de Melo:

User visible changes:

 - Don't open the DWARF info multiple times, keeping instead a dwfl handle
   in struct dso, greatly speeding up 'perf report' on powerpc. (Sukadev Bhattiprolu)

 - Introduce PARSE_OPT_DISABLED option flag and use it to avoid showing
   undersired options in tools that provides frontends to 'perf record', like
   sched, kvm, etc (Namhyung Kim)

Infrastructure changes:

 - More Intel PT work, including a facility to export sample data (comms,
   threads, symbol names, etc) in a database friendly way, with an script to use
   this to create a postgresql database. (Adrian Hunter)

 - Use make sure that thread->mg->machine points to the machine where
   the thread exists (it was being set only for the kmaps kernel modules
   case, do it as well for the mmaps) and use it to shorten function
   signatures (Arnaldo Carvalho de Melo)
