2111c9bace7cSDavid Daney	  blocks into "zones", where each zone is a power of two number of
2112c9bace7cSDavid Daney	  pages.  This option selects the largest power of two that the kernel
2113c9bace7cSDavid Daney	  keeps in the memory allocator.  If you need to allocate very large

2116c9bace7cSDavid Daney
2117c9bace7cSDavid Daney	  This config option is actually maximum order plus one. For example,
2118c9bace7cSDavid Daney	  a value of 11 means that the largest free memory block is 2^10 pages.
