+Subject: [PATCH] pvgrub: fix crash when booting kernel with p2m list outside |
31 |
+ kernel mapping |
32 |
+ |
33 |
+When trying to boot a kernel with the p2m list not mapped by the |
34 |
+initial kernel mapping it can happen that pvgrub is failing as it is |
35 |
+keeping some page tables mapped. |
36 |
+ |
37 |
+Unmap the additional page tables created for the special p2m mapping |
38 |
+will avoid this failure. |
