2176 The kernel memory allocator divides physically contiguous memory
2177 blocks into "zones", where each zone is a power of two number of
2178 pages. This option selects the largest power of two that the kernel
2179 keeps in the memory allocator. If you need to allocate very large
2180 blocks of physically contiguous memory, then you may need to
2181 increase this value.
2182
2183 This config option is actually maximum order plus one. For example,
2184 a value of 11 means that the largest free memory block is 2^10 pages.
2185
2186 The page size is not necessarily 4KB. Keep this in mind
2187 when choosing a value for this option.
