Thanks for spending the time to look at this.  Coaxing me to re-write the
tail of do_machine_check() has made that code much better. Too many
years of one patch on top of another without looking at the whole context.

Cogitate on this series over the weekend and see if you can give me
an Acked-by or Reviewed-by (I'll be adding a #define for BIT(63)).
