I didn't remember either, but having just reviewed my inbox from August, I said that all architectures basically use:
typedef struct { volatile int counter; } atomic_t; #ifdef CONFIG_64BIT typedef struct { volatile long counter; } atomic64_t; #endif
and that should just be put in <linux/atomic_types.h>.
Roman Zippel did me one better and suggested just putting it in types.h, which works for me.
