For example the i386 oops code uses that. That isn't actually an x86 specific feature - it is a requirement across all architectures that get_user() and friends can access kernel areas after set_fs(get_ds()) That's how things like sys_execve() can read the binary headers, etc. See linux/fs/exec.c:kernel_read() for one such example. -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
