I tried to be a party pooper but no. This sounds like a good idea as you
are banking on the 'mm' being the 'active mm'.
sounds like two birds in one shot, I think.
On ia64, we have "tpa" instruction which does the virtual to physical
address conversion for us. But talking to Tony, that will fault during not
present or vhpt misses.
Well, for now, manual walk is probably the best we have.
thanks,
