We want the physical address to be randomized anywhere between 16MB and the top of physical memory (up to 64TB). This patch exchanges the prior slots[] array for the new slot_areas[] array, and lifts the limitation of KERNEL_IMAGE_SIZE on the physical address offset for 64-bit. As before, process_e820_entry() walks memory and populates slot_areas[], splitting on any detected mem_avoid collisions. Finally, since the slots[] array and its associated functions are not needed any more, so they are removed. Based on earlier patches by Baoquan He.
