Pull more parisc updates from Helge Deller:
 "Two small enhancements, which I didn't included in the last pull
  request because I wanted to keep them a few more days in for-next
  before sending upstream:

   - Replace the ldcw barrier instruction by a nop instruction in the
     CAS code on uniprocessor machines.

   - Map variables read-only after init (enable ro_after_init feature)"
