34 | The kernel memory allocator divides physically contiguous memory | ||
35 | blocks into "zones", where each zone is a power of two number of | ||
36 | pages. This option selects the largest power of two that the kernel | ||
37 | keeps in the memory allocator. If you need to allocate very large | ||
38 | blocks of physically contiguous memory, then you may need to | ||
39 | increase this value. | ||
40 | |||
41 | This config option is actually maximum order plus one. For example, | ||
42 | a value of 11 means that the largest free memory block is 2^10 pages. | ||
43 | |||
44 | The page size is not necessarily 4KB. Keep this in mind when | ||
45 | choosing a value for this option. | ||
