hm, why is there no minimal patch against -git that does nothing but 
introduces the new pointer based generic APIs (without using them) - 
such as set_cpus_allowed_ptr(), etc.? 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.
