	* sysdeps/mips/bytesex.h: Add default byte sex.  By Ralf Baechle.

	* sysdeps/unix/sysv/linux/adjtime.c [! MOD_OFFSET]: Use `mode'
	member of `struct timex' instead of `modes'.  From Andreas Schwab.

	* sysdeps/unix/sysv/linux/mknod.c: New file.  Generic C version.
	* sysdeps/unix/sysv/linux/i386/mknod.S: Remove assembler version.

	* sysdeps/unix/sysv/linux/Makefile (inhibit-glue): New variable.
	[$(subdir) = misc] (sysdep_routines): Add mount, umount, and s_ptrace.
	[$(subdir) = misc] (headers): Append sys/mount.h.

	* sysdeps/unix/sysv/linux/mount.S, sysdeps/unix/sysv/linux/umount.S:
	New files.  Implement system calls.
	* sysdeps/unix/sysv/linux/sys/mount.h: New header file.

	* sysdeps/unix/sysv/linux/ptrace.c: New file.  Wrapper around
	ptrace system call.
	* sysdeps/unix/sysv/linux/s_ptrace.S: New file: ptrace system call.

	* sysdeps/unix/sysv/linux/i386/gnu/types.h: New file with correct
	types for i386/Linux.
