Probably use another type of RAM identifier (System RAM (hotplug)). But the point is, if /sys/devices/system/memory also represents all the physical memory present in the system then it might be not be justified to create another similar interface. (Until and unless there is something unique about /sys/firmware/memmap). Thanks Vivek
