Creating the patches should be simple, it's the choice of minimum and maximum values for each architecture that I'd be most concerned about. I'll put them together, though, and the ranges can be changed following discussion with those more knowledgeable, if needed. I also don't have devices on which to test the PowerPC, MIPS and s390 changes, so I'll need someone's help for that.
