If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 20f06ed9f61a185c6dabd662c310bed6189470df Mon Sep 17 00:00:00 2001 From: David Howells <dhowells@xxxxxxxxxx> Date: Wed, 27 Jul 2016 11:43:37 +0100 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.
