For some odd reason we used to return PhysicalPtr for a page_table_base result, but when setting it we accepted only a 32 bit value, so we truncated valid 64 bit addresses into 32 bit addresses by doing that. With this commit being applied, now PageDirectories can be located beyond the 4 GiB barrier.
