The VIRTIO_BALLOON_F_PAGE_POISON feature bit is used to indicate if the
guest is using page poisoning. Guest writes to the poison_val config
field to tell host about the page poisoning value in use.

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.
Negotiation of the VIRTIO_BALLOON_F_FREE_PAGE_HINT feature indicates the
support of reporting hints of guest free pages to host via virtio-balloon.
Host requests the guest to report free page hints by sending a new cmd
id to the guest via the free_page_report_cmd_id configuration register.

In some usages, e.g. virtio-balloon, a kernel module needs to know if
page poisoning is in use. This patch exposes the page_poisoning_enabled
function to kernel modules.

This patch adds support to walk through the free page blocks in the
system and report them via a callback function. Some page blocks may
leave the free list after zone->lock is released, so it is the caller's
responsibility to either detect or prevent the use of such pages.

This paragraph should also be reworked to be part of the normative text
below, I think? The memory barrier must be "between two things"
This patch does three things. Emphasises that the example is pseudo-code
as we tend to stick to C otherwise and tweaks the wording, fixes
a typo in the pseudo code, and removes a line of code that I neither can
see the necessity for nor the sense of.

Occasionally we still use used and available ring instead of Device and
Driver Area respectively. Same goes for descriptor table with the
difference that depending on the context we need either Descriptor Area
or descriptor ring.
Let's clean these up, at least where the cleanup is trivial.

There was a discrepancy between the pseudo code and the
textual description of the algorithm describing how shall
a driver supply buffers to the device.
The textual description did not make sense to me, so I've
changed that one to be more in sync with the pseudo code.

Some of these are more and some are less important. Please
be careful, there is always a chance that I misunderstood something
and that I'm trying to change for the worse.
I've identified some other weak point's too, but tried to
