And the range to sparc64's flush_tlb_pgtables? It's less clear to me

ever partially occupied? A shame to complicate it unnecessarily.
It looks like sparc64 is the only user of this, so it is up to
you Dave.
Oh - one other question too. Doing the unmap and page table freeing in
the same pass will put freed pagecache pages in the same mmu_gather as
the freed page table pages. This looks like it may be a problem for
sparc64?
