Subject: KEYS: 64-bit MIPS needs to use compat_sys_keyctl for 32-bit userspace

From: David Howells <[email protected]>

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.
