Jérôme Gardou d8cdb89fb0 [NTOSKRNL] Overhaul Cc and Mm relationship 
Previously, when creating a file section, Mm requested Cc to cache the file, then Cc would request pages from Mm, then Mm would request them back to serve its file-mapping role
Now, Mm does it all by itself. If file cahcing is requested by the FS driver, then Cc creates a file mapping and uses that to serve its purpose.

This is a rewrite of Cc
