HostHardDisk also gated the 0x8001DD6C force on hive:ddi:words (DumpDdiNopEntry of dump-XIP observe), which is not a reason to refuse VALLOC CallDLL. Only set saw when await is armed and the CallDLL module is ddi_nop ($fp or CallDllStartip module). Clear saw and the poll count when await arms. Remove the hive:ddi:words force gate; keep DumpDdiNopEntry logging. On miss, BootLog BindImp-stall pc once (BinaryDecompress/MapO32 o32[1] if that is the stall). Do not host-CEDecompress .data.
