From 874d5d3ccc04c0659b76b05ee0c761f568062cb1 Mon Sep 17 00:00:00 2001 From: Dave Martin Date: Fri, 14 Jan 2011 00:43:01 +0100 Subject: [PATCH] ARM: 6623/1: Thumb-2: Fix out-of-range offset for Thumb-2 in proc-v7.S Commit d30e45e (ARM: pgtable: switch order of Linux vs hardware page tables) introduced a pre-increment addressing offset which is out of range for Thumb-2. Thumb-2 only permits offsets <256. So split the intruction in two for Thumb-2.
