Hi,

This is a next step of the earlier work I have posted [1].

The first 5 patches are minor cleanups, 6th & 7th try to optimize few
things to make code less complex.

Patches 8-11 actually solve (or try to solve :)) the synchronization
problems, or the crashes I was getting.

And the last one again optimizes code a bit.

I don't get the crashes anymore and want others to try. At least Preeti
and Ke Wang (Sorry if I haven't spelled it properly :( ), as you two
have reported the issues to me.

This patchset should be rebased over the earlier one [1].

To make things simple, all these patches are pushed here [2] and are
rebased over pm/bleeeding-edge because of some recent important changes
there:
