Convert mark_page_accessed() to folio_mark_accessed(). It already operated on the entire compound page, but now we can avoid calling compound_head quite so many times. Shrinks the function from 424 bytes to 295 bytes (shrinking by 129 bytes). The compatibility wrapper is 30 bytes, plus the 8 bytes for the exported symbol means the kernel shrinks by 91 bytes.

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 Restructured Text 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.
