*  The pleasant part of this is that if we need to skip arguments we
 *  can just decrement argc and move argv, because the stack pointer
 *  is utterly unrelated to the location of the environment and
 *  argument vectors.
 *
 * Note that the S/390 people took the easy way out and hacked their
 * GCC to make the stack grow downwards.
 *
 * Final Note: For entry from syscall, the W (wide) bit of the PSW
 * is stuffed into the lowest bit of the user sp (%r30), so we fill
 * it in here from the current->personality
