Help text

This is the offset at which the ~16TB of shadow memory is mapped and used by KASAN for memory debugging. This can be any address that has at least KASAN_SHADOW_SIZE (total address space divided by 8) amount of space so that the KASAN shadow memory does not conflict with anything. The default is 0x100000000000, which works even if mem is set to a large value. On low-memory systems, try 0x7fff8000, as it fits into the immediate of most instructions, improving performance.
