Hi Greg/Sasha

The following 2 patches are backports of

46609ce22703: ("sched/uclamp: Protect uclamp fast path code with static key")
e65855a52b47: ("sched/uclamp: Fix a deadlock when enabling uclamp static key")

into 5.4.y stable tree. The conflict was trivial and due to:

1. uclamp_rq_util_with() was renamed from util_util_with()
2. 2 local variables were converted to unsigned long from unsigned int.

I did do compile test on aarch64 and x86_64 and both looked fine. Beside I ran
a quick and short mmtest to verify the functionality and got the following
results which is inline with what's expected.

I've queued it up, thanks!
