-         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.

+         The kernel page allocator limits the size of maximal physically
+         contiguous allocations. The limit is called MAX_ORDER and it
+         defines the maximal power of two of number of pages that can be
+         allocated as a single contiguous block. This option allows
+         overriding the default setting when ability to allocate very
