Because Linux might use bigger pages than the 4K pages to handle those mmio ioremaps, the kmmio code shouldn't rely on the pade id as it currently does. Using the memory address instead of the page id lets us look up how big the page is and what its base address is, so that we won't get a page fault within the same page twice anymore.
