The documentation seems to still be against it, but, despite that and
the two very valid points raised by Marco (backporting and git-blame),
I think ptep is special and I'm mostly in favor of this change. We may
not need to s/r every instance, but certainly functions which need to
refer to both the pte and the ptep representations of entries becomes
more clear when using the 'p' convention (and then it's nice to have
ptep used everywhere else too for consistency...)

Anyway, just my 2 cents.
