Ryan Libby 13d4f96130 shared shadow vm object invalidation regression test 
Add a regression test for a scenario where a shadow vm object is shared
by multiple mappings.  If a page COW occurs through one of the mappings,
then the virtual-to-physical mapping may become invalidated.

This tests the scenario from CVE-2021-29626 which was fixed by
982693bb72.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
