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

 92	  keeps in the memory allocator.  If you need to allocate very large

 94	  increase this value.
 95
 96	  This config option is actually maximum order plus one. For example,
 97	  a value of 11 means that the largest free memory block is 2^10 pages.
