/* Solaris x86 2.6 and 2.7 targets have a kernel bug when stepping
   over an instruction that causes a page fault without triggering
   a hardware watchpoint. The kernel properly notices that it shouldn't
   stop, because the hardware watchpoint is not triggered, but it forgets
   the step request and continues the program normally.
   Work around the problem by removing hardware watchpoints if a step is
   requested, GDB will check for a hardware watchpoint trigger after the
   step anyway.  */
