+- Kernel commit 5c83511bdb9832c86be20fb86b783356e2f58062 removed
+ pv_init_ops, and commit 054ac8ad5ebe4a69e1f0e842483821ddbe560121
+ removed the Xen-specific paravirt patch function. As a result,
+ pvops Xen dumps are no longer recognized as Xen dumps, and
+ virtual-to-physical translation fails.
+
+ Use the value of xen_start_info to determine whether the kernel
+ is running in Xen PV mode. As suggested by Juergen Gross.
