2187	  The kernel memory allocator divides physically contiguous memory
2188	  blocks into "zones", where each zone is a power of two number of
2189	  pages.  This option selects the largest power of two that the kernel
2190	  keeps in the memory allocator.  If you need to allocate very large
2191	  blocks of physically contiguous memory, then you may need to
2192	  increase this value.
