Subject: [PATCH v1] arm64: Fix size of __early_cpu_boot_status
Date:   Wed, 15 May 2019 19:13:19 +0530
Message-Id: <1557927822-21111-1-git-send-email-arunks@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

__early_cpu_boot_status is of type int. Fix up the calls to
update_early_cpu_boot_status, to use a w register.
