01d,14oct10,jpb  Defect 233321: Edited macros _VX_IS_SYS_MODE_SMP and
                 _VX_IS_SYS_MODE_UP to be true or false on global boolean
                 variable that stores the value of vxSysMode member in
                 _VX_SYS_INFO.
01c,23aug07,kk   added vxSysCpuConfigured and vxSysCpuEnabled fields
01b,23apr07,gls  added _VX_SYS_MODE_MASK
01a,11apr07,gls   written.
