sh: Fixup __strnlen_user() behaviour.
Drop TIF_USERSPACE and add addr_limit to the thread_info struct. Subsequently, use that for address checking in strnlen_user() to ward off bogus -EFAULTs. Make __strnlen_user() return 0 on exception, rather than -EFAULT. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
