See the comment at the top of the new file. To demonstrate the effect,
if a page table had just 16 entries, this would be the set of markers
for a page table with fully contiguous mappings:
index 0 1 2 3 4 5 6 7 8 9 A B C D E F
marker 4 0 1 0 2 0 1 0 3 0 1 0 2 0 1 0
"Contiguous" here means not only present entries with successively
increasing MFNs, each one suitably aligned for its slot, but also a
respective number of all non-present entries.
