[RFC PATCH v1 00/34] VM introspection - EPT Views and Virtualization Exceptions
This patch series is based on the VM introspection patches
(https://lore.kernel.org/kvm/20200721210922.7646-1-alazar at bitdefender.com/),
extending the introspection API with EPT Views and Virtualization
Exceptions (#VE) support.
The purpose of this series is to get an initial feedback and to see if
we are on the right track, especially because the changes made to add
the EPT views are not small
