#     Pull timer fixes from Thomas Gleixner:
#      "Two regression fixes for the timer and timer migration code:
#     
#        - Prevent endless timer requeuing which is caused by two CPUs racing
#          out of idle. This happens when the last CPU goes idle and therefore
#          has to ensure to expire the pending global timers and some other
#          CPU come out of idle at the same time and the other CPU wins the
#          race and expires the global queue. This causes the last CPU to
#          chase ghost timers forever and reprogramming it's clockevent device
#          endlessly.
#     
#          Cure this by re-evaluating the wakeup time unconditionally.
#     
#        - The split into local (pinned) and global timers in the timer wheel
#          caused a regression for NOHZ full as it broke the idle tracking of
#          global timers. On NOHZ full this prevents an self IPI being sent
#          which in turn causes the timer to be not programmed and not being
#          expired on time.
#     
#          Restore the idle tracking for the global timer base so that the
#          self IPI condition for NOHZ full is working correctly again"
