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. Signed-off-by: Dave Martin <dave.martin@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
