From 4a139b64703115e41e1a4e16ebf7eb93d0a0e349 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 9 Aug 2011 12:24:07 +0100 Subject: ARM: versatile: convert logical CPU numbers to physical numbers 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.
