+         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.
+
+         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 page size is not necessarily 4KB.  For example, on 64-bit
+         systems, 64KB pages can be enabled via CONFIG_PPC_64K_PAGES.  Keep
+         this in mind when choosing a value for this option.
