+pygrub: fix extlinux parsing
+
+pygrub was unable to parse extlinux config files correctly, exactly
+the ones like:
+
+LABEL grsec
+  KERNEL vmlinuz-3.0.10-grsec
+  APPEND initrd=initramfs-3.0.10-grsec
+root=UUID=cfd4a7b4-8c40-4025-b877-8205f1c622ee
+modules=sd-mod,usb-storage,ext4 xen quiet
+
+This patch fixes it, adding a new case when parsing the "append" line,
+that searches for the initrd image.

-hvmloader: Switch to absolute addressing for calling hypercall stubs.
-
-This is clearer and less fragile than trying to make relative calls
-work. In particular, the old approach failed if _start was not
-== HVMLOADER_PHYSICAL_ADDRESS. This was the case for some modern
-toolchains which reorder functions.
