Cover letter [PATCH 0/2] x86: Reduce pressure on stack from cpumask usage
Convert cpumask_of_cpu to use a static percpu data array and set_cpus_allowed to pass the cpumask_t arg as a pointer.
Conditioned on NR_CPUS > BITS_PER_LONG.
Compiled and tested for i386 and x86_64. I'd appreciate feedback on other architectures.
(Note: there are still compile/test errors when NR_CPUS > 256 due to cpu id being 8 bits among other things.)
