+Subject: ARM: 7837/3: fix Thumb-2 bug in AES assembler code
+
+From: Ard Biesheuvel <ard.biesheuvel@linaro.org>
+
+commit 40190c85f427dcfdbab5dbef4ffd2510d649da1f upstream.
+
+Patch 638591c enabled building the AES assembler code in Thumb2 mode.
+However, this code used arithmetic involving PC rather than adr{l}
+instructions to generate PC-relative references to the lookup tables,
+and this needs to take into account the different PC offset when
+running in Thumb mode.
