Subject: [PATCH v1 1/8] powerpc/ptdump: Refactor update of st->last_pa
Date: Fri, 19 Jun 2020 15:06:52 +0000 (UTC) [thread overview]
Message-ID: <ac27c8d83e9a8448d39daba162753178978842df.1592578278.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1592578278.git.christophe.leroy@csgroup.eu>
st->last_pa is always updated in note_page() so it can
be done outside the if/elseif/else block.
Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu>
