Naresh, I am having difficult to reproduce this reliablely. If you have
spare cycles, do you mind reverting those to see if you can still
reproduce? I can't seems to find other recent commits more suspicious
than that series.

37e73e3b0a9d drivers: virtio_mem: use pageblock size as the minimum virtio_mem size.
d2b9cd2acb2b mm: cma: use pageblock_order as the single alignment
7f125582227e mm: page_isolation: enable arbitrary range page isolation.
fb009b307b21 mm: make alloc_contig_range work at pageblock granularity
7c7e18d510f4 mm: page_isolation: check specified range for unmovable pages
6a242a94b883 mm: page_isolation: move has_unmovable_pages() to mm/page_isolation.c

$ git revert --no-edit e389355485b7..37e73e3b0a9d
