Once that is upstream all the remaining changes can trickle one arch and one subsystem at a time, and once that's done, the old set_cpus_allowed() can be removed. This is far more manageable than one large patch. and the cpumask_of_cpu() change should be Kconfig based initially - once all arches have moved to it (or even sooner) we can remove that.
