:See PR 16568.  pmap_remove_all() doesn't flush the TLB properly in

    Ahh.  I presume you will commit this patch now that Bjoern has
    confirmed that it works?

    I don't know why an unconditional invltlb() didn't work either,
    it should have.  Maybe the __asm macro is being optimized out.
