I'm not sure how this cross-arch series should be merged -- perhaps thru Andrew Morton's tree? user_regset_copyin_ignore() apparently cannot fail and so always returns 0. Let's first remove the result checks in several architectures that call this function and then make user_regset_copyin_ignore() return *void* instead of *int*...
