Convert the atomic_ptr() operations over to operating on uintptr_t

variables rather than void * variables.  This makes it easier and simpler
to get asm constraints and volatile keywords correct.

MFC after:	3 days
Tested on:	i386, alpha, sparc64
Compiled on:	ia64, powerpc, amd64
Kernel toolchain busted on:	arm
