Patch series "minor fixes and supplement for ptdesc". In this series, the [PATCH 1/3] and [PATCH 2/3] are fixes for some issues discovered during code inspection. The [PATCH 3/3] is a supplement to ptdesc conversion in s390, I don't know why this is not done in the commit6326c26c15("s390: convert various pgalloc functions to use ptdescs"), maybe I missed something. And since I don't have an s390 environment, I hope kernel test robot can help compile and test, and this is why I did not fold [PATCH 2/3] and [PATCH 3/3] into one patch. This patch (of 3): The commit32cc0b7c9d("powerpc: add pte_free_defer() for pgtables sharing page") introduced the use of PageActive flag to page table fragments tracking, so the ptdesc->__page_flags is not unused, so correct the wrong comment.

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.
