[GIT pull] timer fix for 4.13

[Thomas Gleixner]

Linus,

please pull the latest timers-urgent-for-linus git tree from:

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

A single fix for a thinko in the raw timekeeper update which causes clock
MONOTONIC_RAW to run with erratically increased frequency.

Thanks,

	tglx
