6 * -__clear_user( ) called multiple times during elf load was byte loop
10 * -Hand crafted constant propagation for "constant" copy sizes
11 * -stock kernel shrunk by 33K at -O3
14 * -Added option to (UN)inline copy_(to|from)_user to reduce code sz
15 * -kernel shrunk by 200K even at -O3 (gcc 4.2.1)
16 * -Enabled when doing -Os
41 * Returns 0 on success, -EFAULT if not.
42 * @ret already contains 0 - given that errors will be less likely
