lib/raid6: arm: optimize away a mask operation in NEON recovery routine The NEON recovery code was modeled after the x86 SIMD code, and for some reason, that code uses a 16 bit wide signed shift and a mask to perform what amounts to a 8 bit unsigned shift. So fold the ops together. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
