Patch series "page->index removals in mm", v2. As part of shrinking struct page, we need to stop using page->index. This patchset gets rid of most of the remaining references to page->index in mm, as well as increasing the number of functions which take a const folio/page pointer. It shrinks the text segment of mm by a few hundred bytes in my test config, probably mostly from removing calls to compound_head() in page_to_pgoff(). This patch (of 7): Change the function signature to pass in the folio as all three callers have it. This removes a reference to page->index, which we're trying to get rid of. And add kernel-doc.

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.
