how set_pte_at()'s vaddr and ptep args relate
...he current pagetable or not, and it assume they
correspond to the same thing.
For now I've changed kunmap_atomic() to only clear the kmap pte for
mapped high page addresses, but I'm wondering what other places might
use set_pte_at in this way.
Also, it would be useful for Xen to have a set_pte_at_sync, which also
does a TLB flush if necessary, since we can do that in a single operation.
