The first patch fixes a bug due to incorrect DIRECTMAP_SIZE calculation.

The second patch removes unused macro FRAMETABLE_VIRT_END.

The third patch hardens the setup_frametable_mappings by adding a sanity check
for the size of struct page_info and calling panic if the calculate size of
the frametable exceeds the limit.

Sent together for ease of merging.
