Subject: [PATCH 6/7] powerpc/smp: Stop passing mask to update_mask_by_l2
Date:   Mon, 27 Jul 2020 13:25:31 +0530
Message-Id: <20200727075532.30058-7-srikar@linux.vnet.ibm.com>
In-Reply-To: <20200727075532.30058-1-srikar@linux.vnet.ibm.com>

Precedence: bulk

update_mask_by_l2 is called only once. But it passes cpu_l2_cache_mask
as parameter. Instead of passing cpu_l2_cache_mask, use it directly in
update_mask_by_l2.
