Wei-Lin Chang 8673e5b22e KVM: arm64: ptdump: Don't test PTE_VALID alongside other attributes
The attribute masks and test values in the ptdump code are meant for
individual attributes, however for stage-2 ptdump we included PTE_VALID
while testing for R, W, X, and AF. This led to some confusion and the
flipped output for the executable attribute.

Remove PTE_VALID from all attribute masks and values so that each test
matches only the relevant bits.

Additionally, the executable attribute printing is updated to align with
stage-1 ptdump, printing "NX" for non-executable regions and "x " for
executable ones.

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.
