The protocol change and the documentation go together (as separate but
adjacent patches). We bump the number when we change the structure to
accommodate the necessary fields and flags (i.e. a vacuous
implementation), not when we add the full functionality.
The reason I want to do this this way is that I want to also make David
Woodhouse's protocol fixes to make the EFI stub work correctly at the
same time, so we get a single protocol level bump. I think it is better
I merge both sets, and I was hoping to do that tomorrow if possible.
