I haven't the necessary knowledge, but after some talk on IRC I'm
convinced that this patch can't do the job. It will return address that
is higher than MiMdlMappingRegionBase, which means it will not be
accessible in the user mode. Shouldn't each process have it's own MDL
mapping region in it's address space that will be used for this?
