From cb9136d9843e3756ebc79f91a3a522ed4ca73eda Mon Sep 17 00:00:00 2001
From: Tobias Anderberg <tobias.anderberg@axis.com>
Date: Fri, 20 Sep 2002 15:17:16 +0000
Subject: * Added clone() system call. * Proper implementation of
 bits/syscalls.h, no cheating by just including   <asm/unistd.h>. * Proper
 implementation of syscall.S, it no longer contains the   __syscall_error,
 instead it contains code which makes syscall(nr,...) a   system call. * Added
 sysdep.S which contains the code for __syscall_error. * Added some macros to
 sysdep.h. * Added sys/procfs.h, which is needed when compiling with thread
 support. * Removed unused syscall-cris.c.
