When reading through the code, I got the feeling that you should always
be at SPL_HIGH when getting into this function, but occasionally I can
see that it gets called at another IPL on the VAX.
Is that ok? I cannot find a definitive answer right now as I am
Hmm, answering myself...
softint_dispatch() calls softint_execute() which definitely is
documented as must be called at splhigh.
So there would seem to be either a bug in the VAX, or else a bug in the
documentation for softint_execute().
Anyone who can answer which it is.
So far, I've only seen softint_dispatch() being called at SPL_HIGH and
The latter, it would seem, is not correct?
