Replace size_t members with ksize_t (uint64_t) and pointer members (never used as pointers in userspace, but instead as unique idenitifiers) with kvaddr_t (uint64_t). This makes the structs identical between 32-bit and 64-bit ABIs. On 64-bit bit systems, the ABI is maintained. On 32-bit systems, this is an ABI breaking change. The ABI of most of these structs was previously broken in r315662. This also imposes a small API change on userspace consumers who must handle kernel pointers becoming virtual addresses.
