Merge branch 'linus' into sched/urgent, to resolve conflict

 Conflicts:
	kernel/sched/ext.c

There's a context conflict between this upstream commit:

  3fdb9ebcec10 sched_ext: Start schedulers with consistent p->scx.slice values

... and this fix in sched/urgent:

  98442f0ccd82 sched: Fix delayed_dequeue vs switched_from_fair()

Resolve it.
