Block IO core bits for 3.6

Hi Linus,

Later than usual, your merge window coincided with my vacation. I'm sure we both agree that this should never ever happen again. Kthx.

The most complicated part if this is the request allocation rework by Tejun, which has been queued up for a long time and has been in for-next ditto as well. There are a few commits from yesterday and today, mostly trivial and obvious fixes. So I'm pretty confident that it is sound. It's also smaller than usual.

It auto-merges directly into current master, so you should have no trouble with conflict resolutions.

Please pull:
