[PATCH 0/1] MR914: ntoskrnl.exe: Implement various KeQuery* functions

[Etaash Mathamsetty (＠etaash.mathamsetty)]

mrac tries to get function pointers for these functions using MmGetSystemRoutineAddress, I haven't seen them being used by it, but might as well implement it since they are very easy to implement.
