This is intentional. >=20 > Why? Now these intrinsics are available in the main branch. > We should avoid duplicating such code. >=20 >=20 I had asked that the low level intrinsics (UMWAIT/UMONITOR) be split out so= that DLB/DLB2 could use them instead of its own private byte-encoded versi= ons, but instead we have these wrappers that call the low level intrinsics.= Those wrappers introduce additional overhead that is not required for DLB/DLB2. I have a m= eeting with Ma Liang on Monday to discuss.
