Reduce the usage of PageFlag tests and reduce the number of compound_head() calls. For multi-page folios, we'll now show all pages as having the flags that apply to them, e.g. if it's dirty, all pages will have the dirty flag set instead of just the head page. The mapped flag is still per page, as is the hwpoison flag.

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.
