Suravee Suthikulpanit 66ea3f96ae iommu/amd: Modify clear_dte_entry() to avoid in-place update
By reusing the make_clear_dte() and update_dte256().

Also, there is no need to set TV bit for non-SNP system when clearing DTE
for blocked domain, and no longer need to apply erratum 63 in clear_dte()
since it is already stored in struct ivhd_dte_flags and apply in
set_dte_entry().

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.
