Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer updates from Thomas Gleixner:
 "Nothing really exciting this time:

   - a few fixlets in the NOHZ code

   - a new ARM SoC timer abomination.  One should expect that we have
     enough of them already, but they insist on inventing new ones.

   - the usual bunch of ARM SoC timer updates.  That feels like herding
     cats"
