--------------------
01i,29jul10,pad Moved extern C statement after include statements.
01h,27aug08,jpb Renamed VSB header file
01g,24jun08,jpb Added include path for kernel configurations options set in
vsb. Renamed _WRS_VX_SMP to _WRS_CONFIG_SMP.
01f,08sep06,scm update local apic id for cluster & cpu id...
01e,26jul06,scm update for pentium/xeon support...
01d,08mar02,hdn added prototypes for HTT (spr 73738)
01c,21jun01,hdn added support for Pentium4 Local xAPIC
01b,25may98,hdn re-written
01a,26jun97,sub written
