Confused. Where do we call cond_resched() with local interrupts disabled?
Sleeping with local interrupts disabled is usually a bug, so we should prefer
to keep that check in might_sleep().
sys_sched_yield() also calls schedule() with
local interrupts disabled.
It's a bit grubby, but saves a few cycles. Nick and Ingo prefer it that way.
we can remove the irqs_disabled() check in might_sleep then, I'd like to
call might_sleep from cond_resched.
