Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fixes from Thomas Gleixner:
"The last round of minimalistic fixes for clocksource drivers:
- Prevent multiple shutdown of the sh_mtu2 clocksource
- Annotate a bunch of clocksource/schedclock functions with notrace
to prevent an annoying ftrace recursion issue"
