x86_page_size is an enum used to communicate the desired page size with which to map a range of memory. Under the hood they just encode the desired level at which to map the page. This ends up being clunky in a few ways: - The name suggests it encodes the size of the page rather than the level. - In other places in x86_64/processor.c we just use a raw int to encode the level. Simplify this by adopting the kernel style of PG_LEVEL_XX enums and pass around raw ints when referring to the level. This makes the code easier to understand since these macros are very common in KVM MMU code.

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.
