Subject: [PATCH 3/3] ARM: highbank: mask cluster id from cpu_logical_map
Date: Thu, 31 Jan 2013 14:01:14 -0600 [thread overview]
Message-ID: <1359662474-1883-4-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1359662474-1883-1-git-send-email-robherring2@gmail.com>
From: Rob Herring <rob.herring@calxeda.com>
With commit a0ae0240 (ARM: kernel: add device tree init map function),
the cpu id value may include the cluster id and is no longer 0-3, so we
need to mask it now to get the right hard cpu index.
Signed-off-by: Rob Herring <rob.herring@calxeda.com>
