cpumask_t is 512 bytes with NR_CPUS=4096, that's generally considered too big to be on stack.
A number of people spend a lot of time removing cpumask_t from stacks a while ago, I'm very sure they'll not be happy if you're going to add it back.
Rusty, what was the plan on removing cpumask_t altogether?
