Patch series "Various page->flags cleanups". The first two patches are bug fixes, although I'm not sure that either architecture will have noticed. There aren't a lot of uses of page->flags left! The big build-up here is to reworking stable_page_flags(), which will definitely be a user-visible change. I think a welcome one, given the special case we had to spread the Slab flag into all tail pages. This patch (of 10): Since switching to the new page table range API, we do not set the PG_arch_1 (aka dcache clean) flag on tail pages, only on the folio. Test it on the folio. Also use page_mapped() instead of page_mapcount() as it is more efficient.

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.
