This is a bit inconsistent with other address types (hwaddr,
ram_addr_t), no?
-> git grep "_size_t"
What sticks out are "external" mach_vm_size_t and png_size_t.
To me, it logically makes sense that both types are equal, because we're
operating on the same address space (with the same size).
So at least I don't see the benefit here, but I'd love to be enlightened :)
