Currently portions of our preempt logic are written in C while other
parts are written in assembly. There's no reason any of this needs to
live in assembly, so let's move the rest of the lgoic to C. At the same
time, let's make the comment a bit clearer.

Other than the increased lockdep coverage there should be no functional
change as a result of this patch.
