Building cryptodev-2.6 tree with CONFIG_THUMB2_KERNEL=y and CONFIG_CRYPTO_SHA1_ARM=y give following error: AS arch/arm/crypto/sha1-armv4-large.o arch/arm/crypto/sha1-armv4-large.S: Assembler messages: arch/arm/crypto/sha1-armv4-large.S:197: Error: r13 not allowed here -- `teq r14,sp' arch/arm/crypto/sha1-armv4-large.S:377: Error: r13 not allowed here -- `teq r14,sp' arch/arm/crypto/sha1-armv4-large.S:469: Error: r13 not allowed here -- `teq r14,sp' Build can be fixed with adding '.arm' at head of sha1-armv4-large.S. However I'm not sure if this correct fix as this is my first stab at arm assembler and I could not get CONFIG_THUMB2_KERNEL boot up on 'qemu-system-arm -M vexpress-a9' to verify correctness. So this is only build tested.
