Hi all,
While building Linus' tree, today's linux-next build (x86_64
allmodconfig) failed like this:
ERROR: "arbitrary_virt_to_machine" [drivers/xen/xen-gntdev.ko] undefined!
Caused by commit ba5d1012292403c8037adf4a54c4ec50dfe846c4 ("xen/gntdev:
stop using "token" argument").
I have applied this patch for today:

fixes build error:
ERROR: "arbitrary_virt_to_machine" [drivers/xen/xen-gntdev.ko] undefined!
