[PATCH v2 0/6] mm/balloon_compaction: fixes and cleanups

[Konstantin Khlebnikov]

I've checked compilation of linux-next/x86 for allnoconfig, defconfig and
defconfig + kvmconfig + virtio-balloon with and without balloon-compaction.
For stable kernels first three patches should be enough.

changes since v1:

mm/balloon_compaction: ignore anonymous pages
* no changes

mm/balloon_compaction: keep ballooned pages away from normal migration path
* fix compilation without CONFIG_BALLOON_COMPACTION

mm/balloon_compaction: isolate balloon pages without lru_lock
* no changes

mm: introduce common page state for ballooned memory
* move __Set/ClearPageBalloon into linux/mm.h
* remove inc/dec_zone_page_state from __Set/ClearPageBalloon

mm/balloon_compaction: use common page ballooning
* call inc/dec_zone_page_state from balloon_page_insert/delete

mm/balloon_compaction: general cleanup
* fix compilation without CONFIG_MIGRATION
* fix compilation without CONFIG_BALLOON_COMPACTION
