- Fix on-stack hrtimer cleanup in play_idle_precise(), and
add the hrtimer_on_stack cleanup class to facilitate the fix
(Hui Su)
- Fix clock_getres() system call's handling of NULL output

is exactly equal to the nonzero expiry (Hungyu Lin)
- Fix do_timens_ktime_to_host() time offset subtraction underflow
check (Hungyu Lin)
- Report zero remaining time for disarmed SIGEV_NONE posix timers,
and add a self-test to detect this bug in the future (Hung-Jui Lin)
- Fix NOHZ 'full kick' handling bug that can cause missed
tick updates (Peng Wang)
- Fix field access bug in the vdso/gettimeofday code that works
only by accident (Thomas Weißschuh)
