Patch series "Some ptdesc cleanups". The first two patches here are preparation for splitting struct ptdesc from struct page and struct folio. I think their only dependency is on the memdesc_flags_t patches from August which is in mm-new. The third patch is just something I noticed while working on the code. This patch (of 3): Use the new memdesc_flags_t type to show that these are the same bits as page/folio/slab and thesefore have the zone/node/section information in them. Remove a use of ptdesc_folio() by converting pagetable_is_reserved() to use test_bit() directly.

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 reStructuredText 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.
