I split the semaphore simplification work out from my first patch series [0]
because as although the changes came out of that effort, in the end this set
of patches are slightly orthogonal to the goal behind that series and this
ended up being mostly a cleanup with mild bike shedding exercise.
As revealed from the first series, there is some tribal knowledge around
why some binary semaphores are not just mutexes, so we cannot just convert
them all to mutex. So I've extended Peter's patch with some of that tribal
knowledge.
Changes on this v2:
o split this series up into its own
o adopt Peter's patch and extend it with some documentation as to why
some folks stick to binary semaphores over mutexes
o modify kmod.c to use the preferred declaration
This goes boot tested.
