I would not mind if you would take over from here. It seems that I
am into too many things again. Then you can also do the lower
casing that I find inconsistent.

As I pointed out before there are numerous semantic differences that I
noted before. For the transition period where the percpu allocator has a
fixed area there will be issues with an immediate conversion because the
existing allocpercpu allows unbounded allocations and the cpualloc does
not.
