[PATCH v2 4/9] introduce struct slot_area to manage randomization slot info

Kernel is expected to be randomly reloaded anywhere in the whole physical memory area, it could be near 64T at most. In this case there could be about 4*1024*1024 randomization slots. Hence the old slot array will cost too much memory and can not be used any more. Here introduce struct slot_area
