    kernel - Correct unaligned results in alist_free_info()
    
    * alist_free_info() needs to return a power-of-2-sized and power-of-2
      aligned result in order for the caller to be able to use the information
      to allocate the resulting space.
    
    * Fixes an issue where the kernel is unable to return a big chunk of the
      reserved DMA space back to the kernel free pool, resulting in a lot of
      wasted memory.
