Just drop it. It's a conversion, so it doesn't really belong in this "new
API" stuff. Nothing depends on it, and we need to be sure it's that which is
causing the blowup.

Oh, and here's (one) problem:

*nodemask = node_to_cpumask(cpu_to_node(i));

This is an old-style cpumask_t assigment, but nodemask wasn't allocated
NR_CPUS bits if CONFIG_CPUMASK_OFFSTACK. This is why assignment is banned
(and will eventually fail compile), but that conversion hasn't been done on
sched.c yet, so this patch is ahead of its time.
