Finish refactoring the page table logic by threading the PMC state throughout the operation, allowing us to control the operation as we go. Additionally, update the old_addr, new_addr fields in move_page_tables() as we progress through the process making use of the fact we have this state object now to track this. With these changes made, not only is the code far more readable, but we can finally transmit state throughout the entire operation, which lays the groundwork for sensibly making changes in future to how the mremap() operation is performed. Additionally take the opportunity to refactor the means of determining the progress of the operation, abstracting this to pmc_progress() and simplifying the logic to make it clearer what's going on.

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.
