In linux kernel since version 4.14.326 (release Date: 2023-09-23)
The kernel page allocator limits the size of maximal physically
contiguous allocations. The limit is called MAX_PAGE_ORDER and it
defines the maximal power of two of number of pages that can be
allocated as a single contiguous block. This option allows
overriding the default setting when ability to allocate very
large blocks of physically contiguous memory is required.
The maximal size of allocation cannot exceed the size of the
section, so the value of MAX_PAGE_ORDER should satisfy
MAX_PAGE_ORDER + PAGE_SHIFT <= SECTION_SIZE_BITS
Don't change if unsure.
