Subject: [RFC PATCH 8/8] ARM: versatile: convert logical CPU numbers to physical numbers
Date: Tue,  9 Aug 2011 22:42:42 +0100	[thread overview]
Message-ID: <1312926162-22469-9-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1312926162-22469-1-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 pen_release
variable in the SMP boot and CPU hotplug paths.
