1678 The kernel memory allocator divides physically contiguous memory
1679 blocks into "zones", where each zone is a power of two number of
1680 pages. This option selects the largest power of two that the kernel
1681 keeps in the memory allocator. If you need to allocate very large
1682 blocks of physically contiguous memory, then you may need to
1683 increase this value.
1684
1685 This config option is actually maximum order plus one. For example,
1686 a value of 11 means that the largest free memory block is 2^10 pages.
1687
1688 The page size is not necessarily 4KB. Keep this in mind
1689 when choosing a value for this option.
