From e8ce0eb5e2254b85415e4b58e73f24a5d13846a1 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 26 Aug 2011 20:28:52 +0100 Subject: ARM: pm: preallocate a page table for suspend/resume Preallocate a page table and setup an identity mapping for the MMU enable code. This means we don't have to "borrow" a page table to do this, avoiding complexities with L2 cache coherency.
