/*

 * For historic reasons the pipe(2) syscall on MIPS has an unusual calling

 * convention.  It returns results in registers $v0 / $v1 which means there

 * is no need for it to do verify the validity of a userspace pointer

 * argument.  Historically that used to be expensive in Linux.  These days

 * the performance advantage is negligible.
