1273be4cfc Fix a place in the memory manager where it explicitly assumes that the size of a point is 4 bytes. That is OK if the actually size is smaller but makes the heap unstable when used withthe x86_64 host simulation 2014-10-06 12:49:35 -06:00

835c91b03a Add support for a per-process virtual page allocator. This is a new member of the task_group_s structure. The allocaor must be initialized when a new user process is started and uninitialize when the process group is finally destroyed. It is used by shmat() and shmdt() to pick the virtual address onto which to map the shared physical memory. 2014-09-23 16:04:39 -06:00
