Subject: [PATCH 0/5] cpumask: complete CONFIG_CPUMASK_OFFSTACK

This patch series finally gets the last remaining cpumask_t in the core
kernel, and thus allows us to make 'struct cpumask' undefined in the
CONFIG_CPUMASK_OFFSTACK case.  This gives us confidence that noone is
manipulating a cpumask except via the cpumask_ functions, so we can
finally short-allocate them (ie. nr_cpu_ids not NR_CPUS) for the
CONFIG_CPUMASK_OFFSTACK=y case.

This series has been tested on 32-bit only, so handle with care!

Cheers,
Rusty.
