Joonsoo Kim 5842001630 mm/compaction: skip the range until proper target pageblock is met ... Commit 7d49d88683 ("mm, compaction: reduce zone checking frequency in the migration scanner") has a side-effect that changes the iteration range calculation. Before the change, block_end_pfn is calculated using start_pfn, but now it blindly adds pageblock_nr_pages to the previous value. This causes the problem that isolation_start_pfn is larger than block_end_pfn when we isolate the page with more than pageblock order. In this case, isolation would fail due to an invalid range parameter. To prevent this, this patch implements skipping the range until a proper target pageblock is met. Without this patch, CMA with more than pageblock order always fails but with this patch it will succeed.
