Hi Lucas,

looks good, just one idea...

..

> +#define BIT_U8(b)		((u8)(BIT_INPUT_CHECK(u8, b) + BIT(b)))
> +#define BIT_U16(b)		((u16)(BIT_INPUT_CHECK(u16, b) + BIT(b)))
> +#define BIT_U32(b)		((u32)(BIT_INPUT_CHECK(u32, b) + BIT(b)))
> +#define BIT_U64(b)		((u64)(BIT_INPUT_CHECK(u64, b) + BIT(b)))

considering that BIT defines are always referred to unsigned
types, I would just call them

#define BIT8
#define BIT16
#define BIT32
#define BIT64

what do you think?

Andi
