+modification history
+--------------------
+01h,15feb12,zl   use paranthesis around macro arguments (WIND00332849).
+                 moved phys_cpuset access macros from cpusetCommon.h
+01g,30mar10,cww  Added _ASMLANGUAGE protection
+01f,25jan10,d_c  SMP M-N updates: Add access macros for phys_cpuset_t. Add
+                 externs for cpuset_t <-> phys_cpuset_t conversion functions.
+01e,25dec07,l_z  change cpuset computation so that
+                 it works when vxCpuConfigured == 32. Needed especially
+                 for Raza. 
+01d,17oct07,kk   add comment to indicate updates here should also be done in
+                 cpuset.c
+01c,13jun07,jmg  Created cpusetCommon.h and moved most of the file there.
+01b,01mar07,  remove CPUSET_ARG() macro
+01a,25oct06,  created.
