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

Pull timer fixes from Thomas Gleixner:
 "A set of small fixes plus the removal of stale board support code:

   - Remove the board support code from the clpx711x clocksource driver.
     This change had fallen through the cracks and I'm sending it now
     rather than dealing with people who want to improve that stale code
     for 3 month.

   - Use the proper clocksource mask on RICSV

   - Make local scope functions and variables static"
