                             first argument as the destination, the
                             second argument as the virtual address
                             to probe, and the third operand as the
                             privilege level
   IA64_RSM        <RQ>      Generate a reset system mask ('RSM')
                             instruction with the specified mask

                             specifying which application or control
                             register to write and the second
                             operand as the value to write into
