From: David Howells Date: Wed, 27 Jul 2016 10:43:37 +0000 (+0100) Subject: KEYS: 64-bit MIPS needs to use compat_sys_keyctl for 32-bit userspace X-Git-Tag: v4.8-rc1~12^2~34 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=20f06ed9f61a185c6dabd662c310bed6189470df;p=platform%2Fkernel%2Flinux-exynos.git KEYS: 64-bit MIPS needs to use compat_sys_keyctl for 32-bit userspace 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.
