Subject: [PATCH v2 4/8] ARM: exynos4: convert logical CPU numbers to physical numbers
Date: Mon, 15 Aug 2011 18:30:48 +0100 [thread overview]
Message-ID: <1313429452-2820-5-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 pen_release
variable in the SMP boot and CPU hotplug paths.
