Mostafa Saleh a8258ffed2 iommu: debug-pagealloc: Check mapped/unmapped kernel memory
Now, as the page_ext holds count of IOMMU mappings, we can use it to
assert that any page allocated/freed is indeed not in the IOMMU.

The sanitizer doesn’t protect against mapping/unmapping during this
period. However, that’s less harmful as the page is not used by the
kernel.
