Commitb6cb20fdc2("powerpc/book3e: Fix set_memory_x() and set_memory_nx()") implemented a more elaborated version of pte_mkwrite() suitable for both kernel and user pages. That was needed because set_memory_x() was using pte_mkwrite(). But since commita4c182ecf3("powerpc/set_memory: Avoid spinlock recursion in change_page_attr()") pte_mkwrite() is not used anymore by set_memory_x() so pte_mkwrite() can be simplified as it is only used for user pages.

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.
