expand to __attribute__((packed)) and __attribute__((aligned(x))) respectively. Replace the handful of gcc-ism's that use __attribute__((aligned(16))) etc around the kernel with __aligned(16). There are over 400 __attribute__((packed)) to deal with, that can come later. I just want to use __packed in new code rather than add more gcc-ism's.
