hmm lots of changes in cfq, and to be honest the
cfq_exit_single_io_context() change makes me nervous.
The comment says it's called with interrupts disabled, what the comment
does NOT say is that this function ENABLES interrupts!
(the entire cfq change has many places where interrupts now get enabled
where previously they remained as is... )
