parisc: implement full version of access_ok() Up to now PA-RISC could live with a trivial version of access_ok(). Our fault handlers can correctly handle fault cases. But testcases showed that we need a better access check else we won't always return correct errno failure codes to userspace. Problem showed up during 32bit userspace tests in which writev() used a 32bit memory area and length which would then wrap around on 64bit kernel. Signed-off-by: Helge Deller <deller@gmx.de>
