Building error if !PREEMPT_RT:

  CC      kernel/hrtimer.o
kernel/hrtimer.c: In function ‘hrtimer_interrupt’:
kernel/hrtimer.c:1459:27: error: ‘hrtimer_wakeup’ undeclared (first use in this function)
kernel/hrtimer.c:1459:27: note: each undeclared identifier is reported only
  once for each function it appears in
make[1]: *** [kernel/hrtimer.o] Error 1

Patch is here and seems it could be scrolled into
hrtimer-fixup-hrtimer-callback-changes-for-preempt-r.patch :)

Thanks,
Yong
