If you could provide some feedback would be appreciated (really = want to > see MIPS merged with the other archs in 5.3 :) ). Thanks for the quick turnaround on your patch! I'm certainly willing to test it, but in a few hours I'll be spending the bulk of a day on airplanes[1] so it might take a few days until I get to it. Thanks, Paul [1] ...and travel isn't the hackathon it used to be with my 9 month old son around :)
