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

[NTOSKRNL] Place INIT_FUNCTION before the return type (#2823) 
(but after 'static' or SAL 2 annotation.)
Follow-up to 71fefa32, which mentions that it's actually required by the compiler in some circumstances.

Timo Kreuzer 56da95671c [NTOS] Fix a bug in the PE loader, which caused images to be loaded up to MmHighestUserAddress, thus overwriting the shared user page. 
This is now fixed by using MM_HIGHEST_VAD_ADDRESS as the margin instead.
Should fix CORE-11717

Thomas Faber b54e5c689c
[NTOS:MM] Do not map two pages into hyperspace in MiCopyFromUserPage. CORE-14548 
Doing this is not only wrong because it acquires the same spinlock twice,
it also completely breaks the TLB flushing logic in MiMapPageInHyperSpace.
If the PTE with Offset 1 is still valid when a wrap-around to 0 happens,
the TLB flush on wrap-around will not clear the entry for this previous page.
After another loop around all hyperspace pages, page 1 is re-used but its
TLB entry has not been flushed, which may result into incorrect translation.

[NTOSKRNL] Drop the CcTryToInitializeFileCache() which is actually doing nothing relevant 2018-02-07 22:23:49 +01:00
Pierre Schweitzer 07e6e9c9c1
[NTOSKRNL] When marking a BCB dirty, also mark the underlying VACB dirty. 
Experiment and MSDN tend to show that a dirty BCB is queued for lazy write.
This will do the job here!

Also, renamed CcRosMarkDirtyFile() which is more accurate, and added a new
function CcRosMarkDirtyVacb() which just takes a VACB as arg (expected locked)
and marks it dirty (using previous implementation). Make CcRosMarkDirtyFile()
use it.
