    - alpha_ipi_process(): Continue processing IPIs until the ipimask
      reads 0.  Issue a memory barrier between the atomic swap and performing
      the work.
    - alpha_send_ipi(): Issue a memory barrier before setting the ipimask
      to ensure all memory accesses prior to signalling the IPI have
      completed.  Also issue a memory barrier getween setting the ipimask
      and calling PALcode to write the IPIR.
