alpha: unobfuscate _PAGE_P() definition
Way, way back it used to be
_PAGE_NORMAL((x) | ((x & _PAGE_FOW) ? 0 : _PAGE_FOW | _PAGE_COW))
Then (in 1.3.54) _PAGE_COW had died. Result:
_PAGE_NORMAL((x) | ((x & _PAGE_FOW) ? 0 : _PAGE_FOW))
which is somewhat... obscure. What it does is simply
_PAGE_NORMAL((x) | _PAGE_FOW)
and IMO that's easier to follow.
