This patch adds the helper blkcipher_walk_virt_block which is similar to blkcipher_walk_virt but uses a supplied block size instead of the block size of the block cipher. This is useful for CTR where the block size is 1 but we still want to walk by the block size of the underlying cipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
