Subject: [PATCH v2 1/2] powerpc/ptdump: Refactor update of st->last_pa
To:     Benjamin Herrenschmidt <benh@kernel.crashing.org>,
        Paul Mackerras <paulus@samba.org>,
        Michael Ellerman <mpe@ellerman.id.au>
Cc:     linux-kernel@vger.kernel.org, linuxppc-dev@lists.ozlabs.org
Date:   Mon, 29 Jun 2020 11:17:18 +0000 (UTC)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

st->last_pa is always updated in note_page() so it can
be done outside the if/elseif/else block.
