Subject: [PATCH] 2003-02-26  Stuart Menefy <stuart.menefy@st.com>

	Various fixes for SuperH [SH]:
	* mem.c (sys_old_mmap): mmap() parameters passed in registers
	* net.c (sys_pipe), syscall.c (getrval2): pipe() results returned
	in registers
	* process.c (change_syscall): Fixed register which holds system
	call number
	* util.c (arg0_offset, arg1_offset): provide definition
	* Makefile.am: Added new files in linux/sh
	* linux/sh/syscallent.h: New file.
	* linux/sh/errnoent.h: New file.
	* linux/sh/ioctlent.h: New file.
	* linux/sh/signalent.h: New file.
