Building error if !PREEMPT_RT:

  CC      kernel/hrtimer.o
kernel/hrtimer.c: In function =E2=80=98hrtimer_interrupt=E2=80=99:
kernel/hrtimer.c:1459:27: error: =E2=80=98hrtimer_wakeup=E2=80=99 undec=
lared (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
