Ard Biesheuvel	2117eaa62a	crypto: arm/sha1-neon - add support for building in Thumb2 mode ... The ARMv7 NEON module is explicitly built in ARM mode, which is not supported by the Thumb2 kernel. So remove the explicit override, and leave it up to the build environment to decide whether the core SHA1 routines are assembled as ARM or as Thumb2 code.

Ard Biesheuvel	0777e3e172	ARM: 8125/1: crypto: enable NEON SHA-1 for big endian ... This tweaks the SHA-1 NEON code slightly so it works correctly under big endian, and removes the Kconfig condition preventing it from being selected if CONFIG_CPU_BIG_ENDIAN is set.
