These patches, based on viro-vfs/uaccess.metag, add support for RAW_COPY_USER to the metag architecture. Al: Did you want these to go via your uaccess.metag branch? If so I'm happy to create a topic branch with the fixes (patches 1-2, marked for stable) for you to pull, so I can get them upstream for 4.11. - Patch 1 drops some unused macros so they don't need fixing in patch 2. - Patch 2 moves zeroing out to copy_from_user, since __copy_from_user shouldn't cause zeroing, and the existing fixup code didn't properly zero the access that first failed anyway. This is needed for patch 3. - Patch 3 switches metag to using RAW_COPY_USER, which is fairly trivial now that patch 2 moved the zeroing out to copy_from_user. I have a bunch of other usercopy fixes for metag, but it won't hurt for them to go in separately to these patches.
