NTKERNELAPI VOID MmUnmapLockedPages( PVOID BaseAddress, PMDL MemoryDescriptorList );
Pointer to the base virtual address to which the physical pages were mapped.
Pointer to an MDL.
Callers of MmUnmapLockedPages must be running at IRQL <= DISPATCH_LEVEL if the pages were mapped to system space. Otherwise, the caller must be running at IRQL <= APC_LEVEL.
Note that if the call to MmMapLockedPages or MmMapLockedPagesSpecifyCache specified user mode, the caller must be in the context of the original process before calling MmUnmapLockedPages. This is because the unmapping operation occurs in the context of the calling process, and, if the context is incorrect, the unmapping operation could delete the address range of a random process.
