The mmu_gather unification stuff I had did it differently still:

  http://permalink.gmane.org/gmane.linux.kernel.mm/81287

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 :/
