I can't get the same error with net-next + your V7. I have this following e=
rror:

drivers/xen/grant-table.c: In function =91__gnttab_unmap_refs=92:
drivers/xen/grant-table.c:1047:3: error: implicit declaration of function =

   mfn =3D get_phys_to_machine(page_to_pfn(pages[i]));

I'm using this config for Linux: http://xenbits.xen.org/people/julieng/conf=

The kernel repo for the Arndale is completely out-of-date on the wiki page.
I will update the wiki page to use directly the Linaro tree.
