crypto: aes - Use ___cacheline_aligned for aes data
cacheline_aligned is a special section. It cannot be const at the same time because it's not read-only. It doesn't give any MMU protection. Mark it ____cacheline_aligned to not place it in a special section, but just align it in .rodata Cc: herbert@gondor.apana.org.au Suggested-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
