Linux kernel stable tree

When folio is isolated, the PG_lru bit is cleared. So the PG_lru check in stable_page_flags() will miss this kind of isolated folios. Use folio_test_large_rmappable() instead to also include isolated folios. Since pagecache supports large folios and the introduction of mTHP, the semantics of KPF_THP have been expanded, now it indicates not only PMD-sized THP. Update related documentation to clearly state that KPF_THP indicates multiple order THPs.

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.
