Commit message:

MFC r318354 (by cem)

Correct page frame mask constant used in pmap_change_attr_locked

This was introduced in r290156. It's present in 11.0, but not any 10.x
release unless someone decided to MFC it.

It affects ordinary pages right above the DMAP limit, which is effectively
system memory rounded up to a 1 GB (3rd level superpage) boundary (or up to
a minimum of 4 GB, on small systems).
