- 1: No PFN Database exists
- 2: PFN Database exists
- 3: ReactOS NP Pool exists (deprecated)
- Cleanup ReactOS Mm init to work with this.
- ARM3 Phase 1 Init now uses pages directly from the physical memory descriptor.
- This similar to how "MmAllocEarlyPage" used to work.
- A new function MxGetNextPage now does this.
- MxGetNextPage can allocate more than just one page however (making it possible to get contiguous physical memory without going through the PFN-based MmAllocateContiguousMemory beast)
- Also MxGetNextPage will bugcheck with INSTALL_MORE_MEMORY if it runs out of pages.
- Renamed the physical memory descriptor variables to MxFreeDescriptor, MxOldFreeDescriptor instead of MiFreeDescriptor and MiOrgFreeDescriptor (based on NT symbols)
- Nonpaged pool PDEs, PFN database PDEs, and initial nonpaged pool PTEs are now allocated through MxGetNextPage.
- Fix an off by one error in the sizing of MxPfnAllocation.
- The PFN database is now fully "owned" by ARM3 in terms of its PDE mappings and VA location at 0xB0000000.
- ie. MmArmPfnDatabase is now MmPfnDatabase.
- The actual PFN database entries and setup are still done by the ReactOS Mm.
- Got rid of ARM nonpaged pool allocator test.
- Repositioned ReactOS nonpaged pool (deprecated) after the boot image (used to be after the PFN database).
- Paged pool follows.
