I was feeling proactive and took a look at the vmstat code, which is
an amazing piece of work (take my comment however you wish, because it
has multiple implications).

A brief skim shows me that somehow it's related to eintrnames[]
in <sys/interrupt.h>.  How these get strings populated (e.g. "irq##"
vs.  "irq##+"), I have absolutely no idea -- as stated, I cannot
make heads or tails of the code.  (It's architecture-independant
from what the code comments state...)

Regardless, the strings look to be populated somewhere within
kernel-land, not by vmstat.
