* 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.
