  44           Force the each linker list to be aligned to this boundary. This
  45           is required if ll_entry_get() is used, since otherwise the linker
  46           may add padding into the table, thus breaking it.

 477           This is useful for drivers that would otherwise require a lot of
 478           explicit cache maintenance. For some drivers it's also impossible to
 479           properly maintain the cache. For example if the regions that need to
 480           be flushed are not a multiple of the cache-line size, *and* padding
 481           cannot be allocated between the regions to align them (i.e.  if the
 482           HW requires a contiguous array of regions, and the size of each
 483           region is not cache-aligned), then a flush of one region may result
 484           in overwriting data that hardware has written to another region in
 485           the same cache-line. This can happen for example in network drivers
 486           where descriptors for buffers are typically smaller than the CPU
 487           cache-line (e.g.  16 bytes vs. 32 or 64 bytes).
