is there something special about the drm_order() routine in
drivers/char/drm/drm_bufs.c:
=====
/**
* Compute size order. Returns the exponent of the smaller power of two which
* is greater or equal to given number.
*
* \param size size.
* \return order.
*
* \todo Can be made faster.
*/
int drm_order(unsigned long size)
{
int order;
unsigned long tmp;
for (order = 0, tmp = size >> 1; tmp; tmp >>= 1, order++) ;
if (size & (size - 1))
++order;
return order;
}
=====
that it can't simply be replaced by an appropriate call to ilog2()
defined in include/linux/log2.h? just curious.
