Not actually sure about that,. afaict its due to unlocking the base lock
over the callback, which comes from 2d44ae4d7 (hrtimer: clean up
cpu->base locking tricks), and existed before that in the special case
of the scheduler tick (for which this problem is very unlikely to have
ever triggered because we simply don't call start on it when its
running).

Anyway, the patch does look good, so
