In __process_pages_contig() we update page status according to page_ops. That update process is a bunch of 'if' branches, which lie inside two loops, this makes it pretty hard to expand for later subpage operations. So this patch will extract these operations into its own function, process_one_pages(). Also since we're refactoring __process_pages_contig(), also move the new helper and __process_pages_contig() before the first caller of them, to remove the forward declaration.

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.
