Anshuman Khandual 1601df9e36 arm64/mm: Clear PXX_TYPE_MASK and set PXD_TYPE_SECT in [pmd|pud]_mkhuge()
Clear PXX_TYPE_MASK in [pmd|pud]_mkhuge() while creating section mappings
instead of just the PXX_TABLE_BIT and also set PXD_TYPE_SECT. Also ensure
PTE_VALID does not get modified in these helpers, because present-invalid
entries should preserve their state across.

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.
