Currently, RCU spawns kthreads from several different early_initcall()
functions.  Although this has served RCU well for quite some time,
as more kthreads are added a more deterministic approach is required.
This commit therefore causes all of RCU's early-boot kthreads to be
spawned from a single early_initcall() function.

Hey Paul,

I've updated to today's -next and my VM started hanging on boot. Bisect
pointed out this patch.

I don't have any further info right now, but can provide whatever you'll
find useful.


Thanks,
Sasha
