Karol Herbst 8481fdf6dc x86/mm/kmmio: Fix mmiotrace for hugepages ...

commit cfa52c0cfa upstream.

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.
