Patch series "mm/treewide: Replace pXd_large() with pXd_leaf()", v3. 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. This patch (of 10): The two definitions are the same. The only difference is that pXd_large() is only defined with THP selected, and only on book3s 64bits. Instead of implementing it twice, make pXd_large() a macro to pXd_leaf(). Define it unconditionally just like pXd_leaf(). This helps to prepare merging the two APIs.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
