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

From: David Howells <dhowells@xxxxxxxxxx>

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.
