2182 The kernel memory allocator divides physically contiguous memory
2183 blocks into "zones", where each zone is a power of two number of
2184 pages. This option selects the largest power of two that the kernel
2185 keeps in the memory allocator. If you need to allocate very large
2186 blocks of physically contiguous memory, then you may need to
2187 increase this value.
2188
2189 This config option is actually maximum order plus one. For example,
2190 a value of 11 means that the largest free memory block is 2^10 pages.
2191
2192 The page size is not necessarily 4KB. Keep this in mind
2193 when choosing a value for this option.
