+ 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.
