Subject: [GIT PULL] x86/msr changes and x86/cleanups for v4.17

Linus,

Please pull the latest x86-cleanups-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cleanups-for-linus

   # HEAD: 9b9a51354cae933f5640b5bb73bbcd32f989122f x86/msr: Make rdmsrl_safe_on_cpu() scheduling safe as well

The main change is a performance/latency improvement to /dev/msr access.
The rest are misc cleanups.

 Thanks,

	Ingo
