The last patch however is the one Linus hates, it converts i386 to always have a complete pt_regs. Both Josh and me did a bunch of cleanups and the patch is now a net reduction in lines. I still think it is the right thing to do; it removes a whole lot of magic from the C code (and avoids future surprises), but if this cannot convince Linus, I'll not pursue this further.
