Subject: [PATCH v2 6/8] ARM: shmobile: convert logical CPU numbers to physical numbers
Date: Mon, 15 Aug 2011 18:30:50 +0100	[thread overview]
Message-ID: <1313429452-2820-7-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1313429452-2820-1-git-send-email-will.deacon@arm.com>

This patch uses the new cpu_logical_map() macro for converting logical
CPU numbers into physical numbers when dealing with the SCU in the SMP
boot path for sh73a0.
