So first a little bit of infrastructure like commit d5096aa65acd0
("sched: Mark hrtimers to expire in hard interrupt context") is required
so lockdep can see it all properly without RT enabled. Then we need
patches to avoid lockdep complaining about things that are not complained
about in RT because the lock is converted to raw_spinlock_t or something
different is applied so we don't have the warning.
