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

Timo Kreuzer d4b4cf7448 [NTOS:MM] Make sure PXEs/PPEs and PDEs are always MM_EXECUTE_READWRITE 
This is required since the NX protection proagates from the highest level, enforcing NX on the entire range, independent of whether lower level P*Es have the bit set or not. It might be useful to add a platform specific constant to allow making page tables NX on architectures that have a different behavior.
