[PATCH] mm/page_poison: move PAGE_POISON to page_poison.c
The PAGE_POISON macro is used in page_poison.c only, so avoid exporting
it. Also remove the "mm/debug-pagealloc.c" related comment, which is
obsolete.

Why is this an improvement? I thought the whole point of poison.h is to
keep all the poison value at a single place to make them obviously
unique.

[PATCH v28 0/4] Virtio-balloon: support free page reporting
This patch series is separated from the previous "Virtio-balloon
Enhancement" series. The new feature, VIRTIO_BALLOON_F_FREE_PAGE_HINT,
implemented by this series enables the virtio-balloon driver to report
hints of guest free pages to the host. It can be used to accelerate live
migration of VMs. Here is an introduction of this usage:
