Stop setting dirty bits for MMU pages when dirty logging is disabled for a memslot, as PML is now completely disabled when there are no memslots with dirty logging enabled. This means that spurious PML entries will be created for memslots with dirty logging disabled if at least one other memslot has dirty logging enabled. However, spurious PML entries are already possible since dirty bits are set only when a dirty logging is turned off, i.e. memslots that are never dirty logged will have dirty bits cleared. In the end, it's faster overall to eat a few spurious PML entries in the window where dirty logging is being disabled across all memslots.

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.
