  Log:
  SVN rev 223479 on 2011-06-23 16:34:41Z by nwhitehorn
  
  Clear any outstanding atomic reservations when traps are taken. This fixes
  some interesting bugs (mostly on SMP systems) with atomic operations
  silently failing in interrupt heavy situations, especially when using
  overflow pages.
