  	  The kernel memory allocator divides physically contiguous memory
  	  blocks into "zones", where each zone is a power of two number of
  	  pages.  This option selects the largest power of two that the kernel
  	  keeps in the memory allocator.  If you need to allocate very large
  	  blocks of physically contiguous memory, then you may need to
  	  increase this value.
  
  	  This config option is actually maximum order plus one. For example,
  	  a value of 11 means that the largest free memory block is 2^10 pages.
