Heiko Carstens 516bad44b9 s390/gup: fix access_ok() usage in __get_user_pages_fast() ... access_ok() returns always "true" on s390. Therefore all access_ok() invocations are rather pointless. However when walking page tables we need to make sure that everything is within bounds of the ASCE limit of the task's address space. So remove the access_ok() call and add the same check we have in get_user_pages_fast().
