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
32 * where TASK_SIZE could either be retrieved from thread_info->addr_limit or
39 * non-ngeative, which implies that buffer start will be within limit too.
42 * compile time constant, causing first sub-expression to be compile time
45 * The second part would generate weird large LIMMs e.g. (0x6000_0000 - 0x10),
51 ((addr) <= (get_fs() - (sz))))
70 * Returns 0 on success, -EFAULT if not.
71 * @ret already contains 0 - given that errors will be less likely
73 * In case of error, fixup code will make it -EFAULT
