2198 The kernel memory allocator divides physically contiguous memory
2199 blocks into "zones", where each zone is a power of two number of
2200 pages. This option selects the largest power of two that the kernel
2201 keeps in the memory allocator. If you need to allocate very large
2202 blocks of physically contiguous memory, then you may need to
2203 increase this value.
2204
2205 This config option is actually maximum order plus one. For example,
2206 a value of 11 means that the largest free memory block is 2^10 pages.
