Log:
[NTOS]: Cm fixes:
- Rework CmpSetSystemValues() and remove its 1st-stage text-mode setup hack, since I'm
going to have a real hive for the 1st-stage either.
- Lock, then unlock the registry in NtInitializeRegistry when initializing the hives &
flusher.
- Call CmpInitializeHiveList() (i.e., initialize the other hives like \Software, \User,
\.Default) only when we are not in setup-mode.
