Huh?
Intel is still making new 32bit processors with otherwise modern chipsets like tolapai so I don't plan to count anything out. Especially things like the iommu support for irqs may be interesting. Further the iommu irq support is interesting to hypervisors so I would not at all be surprised to see the code getting reused in that context, and with 32bit kernels.
I'm not asking for anyone to unify code they are not touching but rather to code things so unification because trivial. The entire purpose of having arch/x86. We have had this discussion and the viewpoint that we won't add new hardware features to x86_32 and just put it in maintenance mode lost, because the hardware manufactures include Intel have not put x86_32 into strictly maintenance mode.
