Misc timer fixes:

 - 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
   pointer in the !CONFIG_POSIX_TIMERS case (Hungyu Lin)

 - Fix get_cpu_itimer() to return TICK_NSEC when the sampled CPU time
   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)

 - Fix & prevent immediate clocksource watchdog rerun after a delay
   (Karl Mehltretter)

 Thanks,

	Ingo
