#     parisc: Define mb() and add memory barriers to assembler unlock sequences
#     
#     For years I thought all parisc machines executed loads and stores in
#     order. However, Jeff Law recently indicated on gcc-patches that this is
#     not correct. There are various degrees of out-of-order execution all the
#     way back to the PA7xxx processor series (hit-under-miss). The PA8xxx
#     series has full out-of-order execution for both integer operations, and
#     loads and stores.
#     
#     This is described in the following article:
#     http://web.archive.org/web/20040214092531/http://www.cpus.hp.com/technical_references/advperf.shtml
#     
#     For this reason, we need to define mb() and to insert a memory barrier
#     before the store unlocking spinlocks. This ensures that all memory
#     accesses are complete prior to unlocking. The ldcw instruction performs
#     the same function on entry.
