  Modified files:
    sys/ia64/ia64        trap.c 
  Log:
  If the faulting instruction is a cmpxchg, then isr.w and isr.r will both
  be set. We need to check isr.w before isr.r so that we can correctly
  handle a cmpxchg to a copy-on-write page.
  
  This fixes the hang-after-fork problem for dynamically linked programs.
