Joseph Koshy 20c71e39c3 Use a known good stack at the time of servicing an NMI --- reuse 
the space allocated for the double fault handler since this space
is otherwise unused till the time a double fault occurs.

This change should have been committed alongside r1.127 of
"exception.S", but I somehow missed doing so.
