I'd rather keep it all in one place for now. To that end, MISC_CPU and

MISC are callbacks used to print any miscellaneous data.

One might want to add a user option that allows printing by type or by cpu
|

(i.e. print all insn data for each cpu first, or print data cpu by cpu).
|

This may be a case of featuritis so it's currently left out.
