Reserve another HVM context save record ID for this.I have to admit that I have reservations: I didn't really like seeing the original range getting reserved. Even less so I'd like to see extensions / further such reservations. The more that iirc the original reservation was accepted based on a (perhaps vague) promise of the respective uses actually getting upstreamed. Yet that hasn't happened (nor even started to happen) in slightly over 2 years time, iirc. I think this is fair. I hadn't realized we'd sat on this work for so long. What I could see as a compromise is to have, say, vendor ranges higher up in number space. I (personally) would accept removing the reservation entirely -- we didn't follow the upstreaming process, so we take the cost of fixing up any compatibility issues. David
