The first patch adds a generic round_up_pow2() macro to kernel.h. The remaining patches modify a few files to make use of the new macro.
We already have ALIGN() and roundup_pow_of_two().
cool. It doesn't handle x={0,1} though. Maybe we should have:
static inline unsigned long __attribute_const__ __roundup_pow_of_two(unsigned long x)
{
return (1UL << fls(x - 1));
}
static inline unsigned long __attribute_const__ roundup_pow_of_two(unsigned long x)
{
return (unlikely(x<2)?2:__roundup_pow_of_two(x));
}
