The page reporting won't be triggered if the freeing page can't come up
with a free area, whose size is equal or bigger than the threshold (page
reporting order). The default page reporting order, equal to
@pageblock_order, is too huge on some architectures to trigger page
reporting. One example is ARM64 when 64KB base page size is used.
PAGE_SIZE: 64KB
pageblock_order: 13 (512MB)
MAX_ORDER: 14
This specifies the page reporting order to 5 (2MB) for this specific case
so that page reporting can be triggered.
