I strongly dislike it.
Our CPU discovery code is already a big mess, in two separate places,
and this makes it worse.
In theory we have a split between logical and hardware CPU numbers, so
we should just be able to call the whatever CPU we boot on CPU 0. Why
does that not work? And should we fix that?
cheers

Cross-referencing 2 threads on the same topic:
https://patchwork.ozlabs.org/patch/834860
Cascardo recently rebased this patch against latest kernel and tried to
get v3 merged, on the above linked thread.
Let's choose one of the threads to further discuss the solution to this
long-term bug!
Thanks,
Guilherme
