addrmap_phys_to_virt() converts a physical address (phys_addr_t) to a virtual address, so it should return a pointer instead of an unsigned long. Its counterpart, addrmap_virt_to_phys(), takes a pointer, so now they're orthogonal. The only caller of addrmap_phys_to_virt() converts the return value to a pointer anyway.
