Subject: [PATCH v9 0/5] Extend virtio-balloon for fast (de)inflating & fast live migration

This patch series implements two optimizations:
1) transfer pages in chuncks between the guest and host;
2) transfer the guest unused pages to the host so that they
can be skipped to migrate in live migration.

Changes:
v8->v9:
1) Split the two new features, VIRTIO_BALLOON_F_BALLOON_CHUNKS and
VIRTIO_BALLOON_F_MISC_VQ, which were mixed together in the previous
implementation;
2) Simpler function to get the free page block.

v7->v8:
1) Use only one chunk format, instead of two.
2) re-write the virtio-balloon implementation patch.
3) commit changes
4) patch re-org

Liang Li (1):
  virtio-balloon: deflate via a page list

Wei Wang (4):
  virtio-balloon: VIRTIO_BALLOON_F_BALLOON_CHUNKS
  mm: function to offer a page block on the free list
  mm: export symbol of next_zone and first_online_pgdat
  virtio-balloon: VIRTIO_BALLOON_F_MISC_VQ
