Author: sir_richard Date: Tue Oct 5 05:07:13 2010 New Revision: 48992 URL: http://svn.reactos.org/svn/reactos?rev=48992&view=rev Log: [NTOS]: Delete deprecated handling of MEMORY_AREA_IO_MAPPING. Delete all MEMORY_AREA definitions except the ones for SEGMENT_VIEW and VIRTUAL_MEMORY. All other memory is now owned by ARM3! [NTOS]: Delete WriteCopyView flag from MEMORY_AREA (unused, and was taking up 4 bytes due to alignment), and add a Vad pointer (takes up 4 bytes -- no actual size change). [NTOS]: For VM and Section MEMORY_AREAs mapped in user-mode, build a "fake" VAD and insert it into the VAD Root of the Process. This means there is now a consistent view between ARM3 and RosMm in terms of user-mode address space layout, which will come in handy later. [NTOS]: Destroy the MEMORY_AREA's VAD when the MEMORY_AREA itself is deleted. Watch out for the scenario explained in a previous check-in, where the VAD was caught by the MmCleanProcessAddressSpace vad-cleanup-loop. [NTOS]: Implement MiInsertVad to restore the old functionality of MiInsertNode when the current parent and insertion result is not yet known. It obtains the information and calls MiInsertNode.
