I was reviewing your patches, and I don't like the semaphore to spinlock
changes.. There's no reason to start adding spinlocks, unless it's
really performance sensitive which none of those places are.. 

Also the ps3-gelic changes for instance is three locks in one patch. It
should be one lock per patch .. I have a broken out conversion for gelic
which I was going to submit in my next round ..

There's also a number of other people doing these , so you might want to
hold off on doing more unless you know they aren't already completed ..
