The earlier consensus was to just rename KDB_VECTOR to NMI vector.
I added the following patch.
-Andi
Rename KDB_VECTOR to NMI_VECTOR
As a generic NMI IPI vector to be used by debuggers.
And clean up the ICR setup for that slightly (code is equivalent, but cleaner
now)

The patch was obviously half backed. Here's one that actually
compiles.

This doesn't seem too good an idea: the NMI vector really is 0x02
(architecturally), so defining it to something else seems at least odd.

I never understood what this does. If you deliver the IPI as an NMI,
it'll never arrive at this vector, and why would anyone want to put an
"int $NMI_VECTOR" anywhere?

Good point. Actually the consensus (or the patch from T.Rini) was
to name it DEBUG_VECTOR, but I messed that up. Will fix.

You can force an NMI when sending an IPI by setting the right bits
in ICR. That is what it is used for.

??? This is what the code doing the setup does. But the question was -
what do you need the IDT entry for?

Without an IDT entry you cannot receive it?

But that's the point - if it's delivered as an NMI, it'll arrive
through vector 2 (the vector information specified is ignored).
