This patch wasn't quite what I was thinking, but I've realized that
we can't put the params in the .init section, your approach is probably
the best one.

Note that I've just created a series which gets rid of that silly ISBOOL
thing, so you can use the whole field for "level".  Then I set the level
to -1 for the normal calls; I want to use -2 for the early calls, but
that's not done yet...

I'll rework and rebase your patch like that now.

Thanks!
Rusty.
