I use these in the smp-spin-table re-work I am doing to keep a
count of CPUs in the secondary_holding_pen, but those patches
are not yet ready for review.
I thought I'd post this now thinking theses macros might be of use
to someone else. I could just put them into the smp-spin-table
series, please let me know.
