This is really the core part of the patch -- after reversing the
soft_enable logic to be a disable boolean, now it's being extended
to be a disable mask. The exception macro changes just allow an
interrupt type bit to be passed in later.

I should have picked it up earlier, but if you do end up submitting
another version, perhaps consider splitting the disable mask change
and putting it after patch 5.

Thanks,
