modification history
--------------------
01i,09may12,j_l  WIND00337546 - Add vxGdtrSet() and vxLdtrSet() prototypes.
                                Modify vxLdtrGet() prototype.
                 Adhere to coding standards more closely
01h,16feb05,aeg  added various function prototypes (SPR #106381).
01g,24dec03,jb  Adding prototype for vxDsGet
01f,04sep02,hdn  added vxIdleHookAdd(), vxIdleShow() prototype.
01e,11apr02,pai  Added vxCpuShow(), vxDrShow(), and vxSseShow() prototypes.
01d,26mar02,pai  Added vxShowInit() prototype (SPR 74103).
01c,13nov01,ahm  Added rudimentary support for power management (SPR#32599)
01b,26oct01,hdn  added vxDr[SG]et(), vxTss[GS]et() prototype.
01a,22aug01,hdn  written.
