Define independent macros for the RWX protection bits that are enumerated via EXIT_QUALIFICATION for EPT Violations, and tie them to the RWX bits in EPT entries via compile-time asserts. Piggybacking the EPTE defines works for now, but it creates holes in the EPT_VIOLATION_xxx macros and will cause headaches if/when KVM emulates Mode-Based Execution (MBEC), or any other features that introduces additional protection information. Opportunistically rename EPT_VIOLATION_RWX_MASK to EPT_VIOLATION_PROT_MASK so that it doesn't become stale if/when MBEC support is added. 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 reStructuredText 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.
