Subject: [PATCH 2/2] ARM: highbank: convert logical CPU numbers to physical numbers
Date: Tue,  8 Nov 2011 14:34:54 +0000	[thread overview]
Message-ID: <1320762894-11824-3-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1320762894-11824-1-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 releasing CPUs during the SMP
boot and CPU hotplug paths.
