commitdd8de84b57upstream. On FSL_BOOK3E, _PAGE_RW is defined with two bits, one for user and one for supervisor. As soon as one of the two bits is set, the page has to be display as RW. But the way it is implemented today requires both bits to be set in order to display it as RW. Instead of display RW when _PAGE_RW bits are set and R otherwise, reverse the logic and display R when _PAGE_RW bits are all 0 and RW otherwise. This change has no impact on other platforms as _PAGE_RW is a single bit on all of them.

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.
