I'm ok with the patch because it's indeed more logical and clean to pack the info
to a single struct.

But I'm not sure why you think using per-cpu is a problem. It's not only
deemed for optimized local uses, it's also convenient for allocations and
de-allocation, or static definitions. I'm not sure why bootmem would make
more sense.

Other than this in the changelog, the patch is nice, thanks!
