The idea is to have linux personality values that will limit the effective address to different memory range. By default max effective address will be limited to 64TB. Applications can then extend this to 128TB or 512TB. So we will have two personality values PER_LINUX_128TB and PER_LINUX_512TB ? -aneesh
