There is an inconsistency between PMD and PUD-based THP page table helpers like the following, as pud_present() does not test for _PAGE_PSE. pmd_present(pmd_mknotpresent(pmd)) : True pud_present(pud_mknotpresent(pud)) : False Drop pud_mknotpresent() as there are no current users. If/when needed back later, pud_present() will also have to be fixed to accommodate _PAGE_PSE.

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.
