Hi Bruce,

I'm sure you already have -rt2 queued up, but just wanted to mention
that I'm getting this with -rt1:

kernel/built-in.o: In function `register_for_each_vma':
linux/kernel/events/uprobes.c:772: undefined reference to
`percpu_down_write'

which should be fixed by -rt2:

  [- per-cpu rwsem fixed for RT (required only by uprobes so far)]
