Patch series "Use folio APIs in procfs". We're down to very few users of the PageFoo macros, with proc being a major user. After this patchset and another patchset I have for khugepaged, we can get rid of PageActive, PageReadahead and PageSwapBacked. This patchset has the usual advantages in its own right of removing hidden calls to compound_head(). We have the page table lock, so the mapcount & refcount are stable and there can't be any races with folios suddenly becoming tail pages. This patch (of 4): Replaces six calls to compound_head() with one. Shrinks the function from 5054 bytes to 1756 bytes in an allmodconfig build.

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.
