[PATCH 0/5] mm/treewide: Replace pXd_large() with pXd_leaf()

[peterx at redhat.com]

From: Peter Xu <peterx at redhat.com>

[based on latest akpm/mm-unstable, commit 1274e7646240]

These two APIs are mostly always the same.  It's confusing to have both of
them.  Merge them into one.  Here I used pXd_leaf() only because pXd_leaf()
is a global API which is always defined, while pXd_large() is not.

We have yet one more API that is similar which is pXd_huge(), but that's
even trickier, so let's do it step by step.

Some cautions are needed on either x86 or ppc: x86 is currently the only
user of p4d_large(), while ppc used to define pXd_large() only with THP,
while it is not the case for pXd_leaf().  For the rest archs, afaict
they're 100% identical.

Only lightly tested on x86.

Please have a look, thanks.
