Tangentially, I noticed something that BSDi is doing:  There
seems to be a device TRIPLET as opposed to a major,minor tuple.
I wonder if that's for better cloning support...

forms don't have MP hardware anyway (and the ones that do have MP hardware need much more work on their pmaps before they'd be MP-ready). the point of this exercise is to get all platforms using the same pmap API (or at least closer to the same API). having multiple versions of this API present in the tree for extended periods of time seems to me to be a bad idea, so I'd like to fix that. any objections? if not, I'll commit this stuff next weekend. (by the way, I've only tested these changes on i386, alpha, sparc, mac68k sun3 and vax since that's all the hardware I have. if other people could apply http://www.chuq.com/netbsd/diff.byebyepmapnew and test on other non-PMAP_NEW platforms, that would be great.) -Chuck
