[ Upstream commitf7ff3cff35] With the submission of iommu driver for RK3568 a subtle bug was introduced: PAGE_DESC_HI_MASK1 and PAGE_DESC_HI_MASK2 have to be the other way arround - that leads to random errors, especially when addresses beyond 32 bit are used. Fix it.

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.
