PMD 'non-swap' swap entries are currently used for PMD-level migration entries and device private entries. To add to the confusion in this terminology we use is_swap_pmd() in an inconsistent way similar to how is_swap_pte() was being used - sometimes adopting the convention that !pmd_none(), !pmd_present() implies PMD 'swap' entry, sometimes not. This patch handles the low-hanging fruit of cases where we can simply substitute other predicates for is_swap_pmd(). No functional change intended.

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 reStructuredText 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.
