Subject: [GIT PULL] perf events fixes

Linus,

   # HEAD: 91dcfae0ff2b9b9ab03c1ec95babaceefbffb9f4 perf/x86/intel: Do not enable BTS for guests

Two perf events fixes:

 - Fix mmap_count warning & bug when creating a group member event
   with the PERF_FLAG_FD_OUTPUT flag.

 - Disable the sample period == 1 branch events BTS optimization
   on guests, because BTS is not virtualized.

 Thanks,

	Ingo
