-Subject: [PATCH] pvgrub: fix crash when booting kernel with p2m list outside
- kernel mapping
-
-When trying to boot a kernel with the p2m list not mapped by the
-initial kernel mapping it can happen that pvgrub is failing as it is
-keeping some page tables mapped.
-
-Unmap the additional page tables created for the special p2m mapping
-will avoid this failure.
