Some platforms need to fix up the values when reading or writing page
tables. Because of this, the accessors must always be used; it is not
valid to simply dereference a pXX_t pointer.

Move these definitions up by a few lines, so they will be in scope
everywhere that currently dereferences a pXX_t pointer.
