[tkreuzer] 55403: [NTOSKRNL/MM/AMD64] - Add MI_REAL_SYSTEM_RANGE_START, which is the canonical system space base address, while MmSystemRangeStart variable contains a broken value, like on Windows....

Author: tkreuzer Date: Sat Feb 4 10:40:27 2012 New Revision: 55403 URL: http://svn.reactos.org/svn/reactos?rev=55403&view=rev Log: [NTOSKRNL/MM/AMD64] - Add MI_REAL_SYSTEM_RANGE_START, which is the canonical system space base address, while MmSystemRangeStart variable contains a broken value, like on Windows. - Define MmSystemRangeStart to MI_REAL_SYSTEM_RANGE_START, since on amd64 there is no dynamic system space start address and we don't want to use the broken address anywhere - Add some more address layout definitions - Add MiIsPteOnP*eBoundary() macro - Add MMPPE, MI_WRITE_VALID_PPE and ValidKernelPpe definitions - Fix initialization of PrototypePte - Add mappings for VAD bitmap and working set list to MiInitializePageTable - Fix calculations in MiBuildNonPagedPool - Improve MiBuildSystemPteSpace - Implement MiBuildPfnDatabase, MiAddDescriptorToDatabase, MiBuildPfnDatabaseFromPageTables, MiSetupPfnForPageTable all of these are written to be portable, yet they are untested on anything else than amd64 builds -
