That seems reasonable.

I'm wondering if we can now remove the printk_sched() special-case. 
iirc, that was needed because wake_up(klogd) would deadlock when called
from sched internals.  But now that wakeup is punted to the timer tick,
perhaps this is now unnecessary?

(Maybe there were other problems, but the 3ccf3e8306 is poor, and its
author is unavailable.  There's a lesson there!)
