Could you avoid needing the nodemask_t 'ret' on the stack, by passing
in a "nodemask_t *" pointer to where you want the resulting nodemask_t
written, rather than by returning it by value?

static void mpol_relative_nodemask(nodemask_t *ret, const nodemask_t *orig,
const nodemask_t *rel)

I won't rest till it's the best ...
