A length that exceeds the real size of the inode may be
specified from user, although these out-of-range areas
are not mapped, but they still need to be check in
while loop, which is unnecessary.

Every described BCM4908 board has WP pin not connected. This caused

Some laptops where the thermal control is handled by the EC may
