I must admit to not having spent any time thinking about this, but aren't we moving the entries from one set of page tables to the other, leaving the pte_t entries unchanged. I guess I should go look, but could you provide a quick pointer in the proper direction as to why we need to recall externals when the before and after look of these page tables will have the same information for the TLBs.
