With the range check it is possible to do a quick verification that the current mapping is correct vs. the static protection areas. In case a incorrect mapping is detected a warning is emitted and the large page is split up. If the large page is a 2M page, then the split code is forced to check the static protections for the PTE entries to fix up the incorrectness. For 1G pages this can't be done easily because that would require to either find the offending 2M areas before the split or afterwards. For now just warn about that case and revisit it when reported.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
