I know, there is a collision with a patch in linux-next that replaced
alloc_cpumask_var/cpumask_clear with the zalloc version.

(a) Either that patch should be adapted to change also the new allocation.
(b) I can also change all those allocation to zalloc with my patch.

Make your choice:

[ ] (a)
[ ] (b)
