Lu Baolu 6f2c72738d iommu/vt-d: Remove incorrect PSI capability check
commit f81b846dcd9a1e6d120f73970a9a98b7fcaaffba upstream.

The PSI (Page Selective Invalidation) bit in the capability register
is only valid for second-level translation. Intel IOMMU supporting
scalable mode must support page/address selective IOTLB invalidation
for first-level translation. Remove the PSI capability check in SVA
cache invalidation code.

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.
