Looks like few of them are interested with this BIT macro, but I'm thinking this is not the right place just add above BIT_MASK @@ -104,6 +104,7 @@ static inline unsigned int generic_hweight8(unsigned int w) return (res & 0x0F) + ((res >> 4) & 0x0F); } +#define BIT(nr) (1UL << (nr)) #define BIT_MASK(nr) (1UL << ((nr) % BITS_PER_LONG)) #define BIT_WORD(nr) ((nr) / BITS_PER_LONG) this will give an impression to have all BIT macro's at once like Linux. > /* > * ffs: find first bit set.
