[GIT PULL] perf fixes

[Ingo Molnar]

Linus,

Please pull the latest perf-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus

   # HEAD: 849e96f30068d4f6f8352715e02a10533a46deba Merge tag 'perf-urgent-for-mingo-5.2-20190528' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

On the kernel side there's a bunch of ring-buffer ordering fixes for a 
reproducible bug, plus a PEBS constraints regression fix - plus tooling 
fixes.

 Thanks,

	Ingo
