[NTOSKRNL]
- Pass a placeholder trap information, indicating that we are unlocked, to MmAccessFault
in MmProbeAndLockPages as temporary hack until Mm locking is fixed
- Fixes "Assertion 'GuardedMutex->Owner == KeGetCurrentThread()'
failed" when faulting in pages via MmProbeAndLockPages
- Dedicated to Jim :)
