The mmu_gather unification stuff I had did it differently still:

That said, I do like Linus' approach. The only thing I haven't
considered is if it does the right thing for tile,mips-r4k which have
'special' rules for VM_HUGETLB. Although I don't think it changes those
archs enough to break anything.

I should find some time to finally finish that series :/
