it again) if the "dd" (data debug fault disable) bit in the processor
status word is set.
This PSR bit is set in ia64_linux_stopped_by_watchpoint when the
code there has determined that a hardware watchpoint has indeed
been hit. The CPU will then be able to execute one instruction
without triggering a watchpoint. */
