#     mm: page_alloc: validate buddy before check its migratetype.
#     
#     Whenever a buddy page is found, page_is_buddy() should be called to
#     check its validity.  Add the missing check during pageblock merge check.
#     
#     Fixes: 1dd214b8f21c ("mm: page_alloc: avoid merging non-fallbackable pageblocks with others")
