Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fixes from Thomas Gleixner:
"Viresh unearthed the following three hickups in the timer/timekeeping
code:
- Negated check for the result of a clock event selection
- A missing early exit in the jiffies update path which causes
update_wall_time to be called for nothing causing lock contention
and wasted cycles in the timer interrupt
- Checking a variable in the NOHZ code enable code for true which can
only be set by that very code after the check succeeds. That
results in a rock solid runtime disablement of that feature"
