In ARM 64-bits, memory size can be supported is more than 4GB, hence increasing save array is needed to cope with testing larger memory.

Changes in v2:

• Change save array size to save[BITS_PER_LONG - 1]

• long save[31];

• long save[BITS_PER_LONG - 1]; long save_base; long cnt; long val;

Does this work with LPAE systems, where bits per long == 32 and the address space is bigger ? Or with similar setups ? I mean, you can have

4 GiB of RAM on 32bit system ...
