This patchset consists of several parts. Patches [1-2] optimize
likely case of request_end(), and make this function to take
fiq->waitq.lock only, when it is really needed. This improves
performance of this function completes.
Patch 3 makes request_end() to call wake_up() only for not
background requests (background requests never wait answer),
and this optimizes this function a bit more
Patches [4-6] makes code to check userspace requests correct
interrupt id to requeue (whether we've sent this interrupt).
