pagemap: introduce pagemap_entry_t without pmshift bits
These bits are always constant (== PAGE_SHIFT) and just occupy space in the entry. Moreover, in next patch we will need to report one more bit in the pagemap, but all bits are already busy on it. That said, describe the pagemap entry that has 6 more free zero bits.
