When finishing guest page faults, don't mark pages as accessed if KVM is resuming the guest _without_ installing a mapping, i.e. if the page isn't being used. While it's possible that marking the page accessed could avoid minor thrashing due to reclaiming a page that the guest is about to access, it's far more likely that the gfn=>pfn mapping was was invalidated, e.g. due a memslot change, or because the corresponding VMA is being modified.

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.
