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

v2:
- Added patch "mm/ppc: Replace pXd_is_leaf() with pXd_leaf()" [Christophe]
- Added patch "mm/x86: Drop two unnecessary pud_leaf() definitions" [syzbot]
- Touched up two more comments which also referenced pmd_large()

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 special cares are taken for ppc and x86, they're done as separate
cleanups first.  Only lightly tested on x86.

Please have a look, thanks.
