Subject: [PATCH 0/2] x86: Reduce pressure on stack from cpumask usage
Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org


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.)
