Bit 7 in the leaf node is normally programmed with pat[2], however with 2M/1G pages that same bit in the PDE/PDPE also toggles 2M/1G pages. For 2M/1G entries the pat[2] is rather moved to bit 12, which is now free given that the address must be aligned to 2M or 1G, leaving bit 7 for toggling 2M/1G pages.

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.
