[Ingo Molnar]

hi Greg,

Please merge the following upstream perf commits into v4.1.1:

  git merge 75e84ab906ef

This will merge the following fixes:

  2f993cf09364 ("perf: Fix ring_buffer_attach() RCU sync, again")
  4b36f1a4139c ("perf/x86: Add more Broadwell model numbers")
  6b099d9b040b ("perf/x86/intel/bts: Fix DS area sharing with x86_pmu events")
  1b7b938f1817 ("perf/x86/intel: Fix PMI handling for Intel PT")
  2c33645d366d ("perf/x86: Honor the architectural performance monitoring version")
  75e84ab906ef ("perf tools: Fix build breakage if prefix= is specified")

Note: commit IDs are listed in cherry picking order, in case you want to 
cherry-pick them.

Thanks,

	Ingo

Please disregard all these sha1's for the time being, as a regression has just 
been bisected back to:

   1b7b938f1817 ("perf/x86/intel: Fix PMI handling for Intel PT")

Thanks,

Ok, should I just ignore all of these then?  Don't you want the other
patches before that one merged?

thanks,

Yeah, so you can apply:

   2f993cf09364 ("perf: Fix ring_buffer_attach() RCU sync, again")
   4b36f1a4139c ("perf/x86: Add more Broadwell model numbers")
   6b099d9b040b ("perf/x86/intel/bts: Fix DS area sharing with x86_pmu events")

And in fact you can apply these two too:

   2c33645d366d ("perf/x86: Honor the architectural performance monitoring version")
   75e84ab906ef ("perf tools: Fix build breakage if prefix= is specified")

as they are independent.

It's only 1b7b938f1817 that was borked.

Thanks,

	Ingo
