Thierry reported that the "iron out" patch for isolate_freepages_block()
had problems due to the strict check being too strict with "mm: compaction:
Iron out isolate_freepages_block() and isolate_freepages_range() -fix1".
It's possible that more pages than necessary are isolated but the check
still fails and I missed that this fix was not picked up before RC1. This
same problem has been identified in 3.7-RC1 by Tony Prisk and should be
addressed by the following patch.
