Pull timer fixes from Thomas Gleixner:
"Two fixes for the time/timers subsystem:
- Invert the inverted fastpath decision in check_tick_dependency(),
which prevents NOHZ full to stop the tick. That's a regression
introduced in the 7.0 merge window.
- Prevent a unpriviledged DoS in the clockevents code, where user
space can starve the timer interrupt by arming a timerfd or posix
interval timer in a tight loop with an absolute expiry time in the
past. The fix turned out to be incomplete and was was amended
yesterday to make it work on some 20 years old AMD machines as
well. All issues with it have been confirmed to be resolved by
various reporters"
