Merge branch 'sched/urgent' into sched/core, to resolve conflicts

This commit in sched/urgent moved the cfs_rq_is_decayed() function:

  a7b359fc6a37: ("sched/fair: Correctly insert cfs_rq's to list on unthrottle")

and this fresh commit in sched/core modified it in the old location:

  9e077b52d86a: ("sched/pelt: Check that *_avg are null when *_sum are")

Merge the two variants.

Conflicts:
	kernel/sched/fair.c
