AFAICT, in 4.19, sector_t is not guaranteed to be u64, see
include/linux/types.h. So we can't take this.

AFAICT, we don't have those NULL assignments in expire_timers in
4.19. Can someone doublecheck this? We also don't support PREEMPT_RT
there.

AFAICT this is just a cleanup. We should not need this.

> Sean Anderson <sean.anderson@...ux.dev>
>     soc: fsl: qbman: Use raw spinlock for cgr_lock

As we don't have commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth
on rate change") in 4.19, we should not really need this. Plus, 10msec
under raw spinlock is quite evil, such kernel is not realtime any
more. We should not be doing that.

Best regards,
