Hi,

allyesconfig and multi_v7_defconfig fail to build on recent linux-next
on GCC 6.2.0.

Errors:
../arch/arm/crypto/aes-cipher-core.S: Assembler messages:
../arch/arm/crypto/aes-cipher-core.S:21: Error: selected processor does not support `tt .req ip' in ARM mode
../arch/arm/crypto/aes-cipher-core.S:174: Error: ARM register expected -- `movw tt,#:lower16:crypto_ft_tab'
../arch/arm/crypto/aes-cipher-core.S:174: Error: ARM register expected -- `movt tt,#:upper16:crypto_ft_tab'

Compiler: arm-linux-gnueabi-gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005

Git bisect pointed to:
first bad commit: [81edb42629758bacdf813dd5e4542ae26e3ad73a] crypto: arm/aes - replace scalar AES cipher

Best regards,
Krzysztof
