Ah, yeah, no. That's a known issue which we *finally* managed to track
down last week. Unfortunately this sched/urgent pull does not yet
include those patches.

If you want them, they can be had here:

git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git sched/urgent

I was meaning to push them to tip/sched/urgent on Monday, so they'd be
in next week's batch.

But if people want them now, have at :-)
