From: David Howells <dhowe...@redhat.com> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit 20f06ed9f61a185c6dabd662c310bed6189470df upstream. MIPS64 needs to use compat_sys_keyctl for 32-bit userspace rather than calling sys_keyctl. The latter will work in a lot of cases, thereby hiding the issue.
