modification history
--------------------
01v,24feb11,elp added vxsimHostCpuDelay() vxsimHostCpuWakeup()
(CQ:WIND00151275).
01u,29dec10,dbt Fixed _SIMIA_PER_CPU_VALUE32_INC macro in 64-bit mode to
correct return value.
01t,18oct10,elp implement LP64 SMP macros.
01s,03aug10,elp fixed _SIMIA_PER_CPU_ADRS_GET(64 bits).
01r,29jul10,pad Moved extern C statement after include statements.
01q,02jun10,elp 64 bits support.
01p,15may09,gls moved VX_INSTR_BARRIER() to vxAtomicArchLibCommon.h
01o,26sep08,gls added _WRS_KERNEL_LOCK_VAR_ALIGN
01n,27aug08,jpb Renamed VSB header file
01m,24jun08,jpb Added include path for kernel configurations options set in
vsb. Renamed _WRS_VX_SMP to _WRS_CONFIG_SMP.
01l,18jan08,gls added VX_INSTR_BARRIER()
01k,09jan08,elp removed previous temporary fix.
01j,19jul07,rlp Declared vxsimHostSleep() as extern, this is a temporary fix
to be able to build the aim directory.
01i,16jul07,elp added _WRS_ARCH_CPU_DELAY() macro.
01h,17apr07,kk move VX_MAX_SMP_CPUS to archSimnt.h
01g,16mar07,elp fixed cplus build
01f,08mar07,dbt Removed inclusion of mmuArchLib.h
01e,19dec06,elp added macros to get WIND_VARS locked, moved simStatus and
simPendingIntLvl to host variables.
01d,11dec06,kk removed references to VX_KERNEL_VARS define, no longer needed
01c,30nov06,dbt Increased maximum number of CPUs to 32.
01b,23nov06,dbt Fixed syntax for GNU compiler.
Removed _WRS_WIND_VARS_OFFSET_archVars definition
Increased maximum CPU number to 16
01a,07sep07,elp created
