From 62b2d07c0ea9db40a1787d2d0ab49f03c3e0613c Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 31 Aug 2011 23:26:18 +0100 Subject: ARM: pm: get rid of cpu_resume_turn_mmu_on We don't require cpu_resume_turn_mmu_on as we can combine the ldr instruction with the following code provided we ensure that cpu_resume_mmu is aligned for older CPUs. Note that we also align to a 32-byte boundary to ensure that the code can't cross a section boundary.
