 47	  with lots of compiled-in functionality may require a larger range
 48	  for function calls. Use this option to have the compiler generate
 49	  function calls with 32-bit range. This will make the kernel both
 50	  larger and slower.

 92	  pages.  This option selects the largest power of two that the kernel
 93	  keeps in the memory allocator.  If you need to allocate very large
 94	  blocks of physically contiguous memory, then you may need to
 95	  increase this value.
 96
 97	  This config option is actually maximum order plus one. For example,
 98	  a value of 11 means that the largest free memory block is 2^10 pages.
