From 1a4baafa7d203da1cceb302c2df38f0fea1c17a1 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 15 Nov 2011 13:25:04 +0000 Subject: ARM: proc-*.S: place cpu_reset functions into .idmap.text section The CPU reset functions disable the MMU and therefore must be executed with an identity mapping in place. This patch places the CPU reset functions into the .idmap.text section, causing the idmap code to include them as part of the identity mapping.
