d52f937120 [KMTESTS:NTOS_MM] Purge & flush cache when there is a data section object. 
Those purge & flush the mapped sections too. That's what fastfat_new & other FS drivers do.

b0c143c710 [NTOS:MM][NTOS:CC][FASTFAT][FASTFAT_NEW] Massive overhaul 
- Make Cc be a client of Mm
   - Cc now creates a section object for each Shared cache map it creates
   - Some functions where introduced into Mm in order to let Cc make notice of dirtified pages, file flushes & purges, etc.
 - Make Mm the real master of how pages are kept in memory for mapped files (including cached files)
   - Keep track of dirty pages
   - Do not dismiss pages as soon as section object are closed
 - Fine tune the balancer to account for this changes (far from perfect yet)
 - Those changes are incompatbile with fastfat -> enable fastfat_new
   - Make Cc routines compatible with it, esp. regarding file locking, write-behind, etc.
