- Get rid of mm/mmsup.c and move some of the ROS-internal functions better where they belong.
- Add ARM3/mmsup.c for miscellaneous function helper functions. - Implemented: - Move MmIsRecursiveIoFault, MmIsThisanNtAsSystem and MmQuerySystemSize. These belong here. - Unimplemented: - Move MmSetBankedSection and fix the prototype. This should probably go somewhere else later. - Move MmAdjustWorkingSetSize and fix the prototype. This should probably go in procsup.c later. - Move MmMapUserAddressesToPage. This should also probably go in procsup.c later. - Move MmSetAddressrangeModified and MmIsNonPagedsystemAddressValid. These should probably go somewhere else later. svn path=/trunk/; revision=43481
