Use common logic for computing PT_BASE_ADDR_MASK for 32-bit, 64-bit, and EPT paging. Both PAGE_MASK and the new-common logic are supsersets of what is actually needed for 32-bit paging. PAGE_MASK sets bits 63:12 and the former GUEST_PT64_BASE_ADDR_MASK sets bits 51:12, so regardless of which value is used, the result will always be bits 31:12. 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 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.
