However, there are some exceptions that can be found in the standard

relinquish_pages() deals with interrupted de-validation in a fairly

letting the page "fall through" to the "force invalidate" loop below.
This requires an extensive comment describing what needs to happen to

In order to better test hypervisor preemption paths, add an option to

The comment about the "force-invalidate" loop gives two reasons for
its existence:
1. Breaking circular "linear pagetable" references
2. Cleaning up partially-validated pages.
The first reason been invalid since XSA-240: Since then it hasn't been
possible to generate circular linear pagetable re
