The interface used to communicate with the firmware casts pointers into unsigned longs and back again in order to store private references, all of this for pointers that remain purely in the kernel. Replace these unsigned longs with void pointers to make the code a bit sturdier and easier to follow. Also simplify some interfaces by removing arguments that could be infered from others.
