Paul E. McKenney 8db559b830 rcu: add memory barriers and comments to rcu_check_callbacks() ...

Add comments to the logic that infers quiescent states when interrupting
from either user mode or the idle loop.  Also add a memory barrier: it
appears that James Huang was in fact onto something, as the scheduler
is much less synchronization happy than it once was, so we can no longer
rely on its memory barriers in all cases.
