There is odd behaviour when we steal freepages from other migratetype buddy list. In try_to_steal_freepages(), we move all freepages in the pageblock that founded freepage is belong to to the request migratetype in order to mitigate fragmentation. If the number of moved pages are enough to change

[PATCH 3/4] mm/compaction: enhance compaction finish condition

Compaction has anti fragmentation algorithm. It is that freepage should be more than pageblock order to finish the compaction if we don't find any freepage in requested migratetype buddy list. This is for mitigating fragmentation, but, it is a lack of migratetype consideration and too excessive.

[PATCH v14 1/7] ARM: probes: move all probe code to dedicate directory

In discussion on LKML (https://lkml.org/lkml/2014/11/28/158), Russell King suggests to move all probe related code to arch/arm/probes. This patch does the work. Due to dependency on 'arch/arm/kernel/patch.h', this patch also moves patch.h to 'arch/arm/include/asm/patch.h', and related '#include'

[PATCH v14 0/7] ARM: kprobes: OPTPROBES and other improvements.
