Subject: [PATCH v1 02/15] powerpc/uaccess: Define ___get_user_instr() for ppc32
Date: Thu, 25 Feb 2021 17:50:31 +0000 (UTC) [thread overview]
Message-ID: <03d1f57f73c74748829994f8026cb274065c1d8d.1614275314.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1614275314.git.christophe.leroy@csgroup.eu>
Define simple ___get_user_instr() for ppc32 instead of
defining ppc32 versions of the three get_user_instr()
helpers.
