AW: Best way to align key in AES context

Hi, I want to ensure that the key data in an AES ctx structure is 8 byte aligned to avoid aligment exceptions afterwards. Other fields don't need that restriction. At the moment I'm using the following (ugly) implementation. struct ppc_aes_ctx { u32 rounds; u32 *key_enc; u
