I guess this is ok.
I would have switched things around such that tlb_flush_page_bits_locked used
tlb_flush_range_locked, passing TARGET_PAGE_SIZE for the length.
I would check for a very long length and flush the whole tlb, lest we spend too
long going round and round the same set of tlb entries.
I would not skip the third function in the triple, *_all_cpus, which is unused
by arm but we have for every other tlb flushing function in this set.
I'll whip something up and post it.
