The vma addresses in binder are currently stored as void __user *. This
requires casting back and forth between the mm/ api which uses unsigned
long. Since we also do internal arithmetic on these addresses we end up
having to cast them _again_ to an integer type.
Lets stop all the unnecessary casting which kills code readability and
store the virtual addresses as the native unsigned long from mm/. Note
that this approach is preferred over uintptr_t as Linus explains in [1].
Opportunistically add a few cosmetic touchups.
