+--------------------
+01j,26jul12,sye  Removed duplicate method declaration. (WIND00365654)
+01i,31jan11,to   WIND00251990: restore backward compatibility for ILP32
+01h,27may10,pad  Added 'extern C' statement.
+01g,14may10,cww  LP64 adaptation
+01f,26jan10,d_c  SMP M-N updates: Change VXIPI_EMIT_FUNC type to pass
+                 a physical CPU set (phys_cpuset_t). Add prototype
+		 for vxIpiPhysEmit()
+01e,23sep08,kab  Fix CQ:133672 - AMP cannot share SMP IPI
+                 Added IPI_INTR_ID_MIPC
+01d,16feb08,zl   added IPI_INTR_ID_SCHED
+01c,01jun07,tor  prevent recursive inclusion
+01b,04apr07,tor  change CPC to VXCPC
+01a,27Mar07,tor  created
