Subject: [PATCH] powerpc/32s: Fix another build failure with CONFIG_PPC_KUAP_DEBUG
Date: Fri, 29 May 2020 18:50:43 +0000 (UTC)	[thread overview]
Message-ID: <5ce7982c72424eb3e7abf78063d454c38c42b343.1590778219.git.christophe.leroy@csgroup.eu> (raw)

From: Christophe Leroy <christophe.leroy@c-s.fr>

'thread' doesn't exist in kuap_check() macro.

Use 'current' instead.

Fixes: a68c31fc01ef ("powerpc/32s: Implement Kernel Userspace Access Protection")
