	  This is useful for drivers that would otherwise require a lot of

	  cannot be allocated between the regions to align them (i.e.  if the
	  HW requires a contiguous array of regions, and the size of each
	  region is not cache-aligned), then a flush of one region may result
	  in overwriting data that hardware has written to another region in
	  the same cache-line. This can happen for example in network drivers
	  where descriptors for buffers are typically smaller than the CPU
	  cache-line (e.g.  16 bytes vs. 32 or 64 bytes).
