	  Some SH processors (such as SH-2/SH-2A) lack an MMU. In order to
	  boot on these systems, this option must not be set.

	  On other systems (such as the SH-3 and 4) where an MMU exists,
	  turning this off will boot the kernel on these machines with the
	  MMU implicitly switched off.

	  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.
