From mboxrd@z Thu Jan 1 00:00:00 1970 From: will.deacon@arm.com (Will Deacon) Date: Thu, 4 Nov 2010 17:30:45 +0000 Subject: [PATCH] ARM: vexpress ct-ca9x4: only set twd_base if local timers are being used Message-ID: <1288891845-12630-1-git-send-email-will.deacon@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org In commit bde28b84, I made the assumption that CONFIG_SMP is always set for the quad-core ct-ca9x4 platform. As it turns out, people who aren't using the SMP goodness are confronted with a build failure. This patch fixes this issue by ensure that twd_base is only set if local timers are being used (and therefore SMP support is configured).
