Subject: [PATCH v11 QEMU 2/3] virtio-balloon: Add bit to notify guest of
 unused page reporting

From: Alexander Duyck <alexander.h.duyck@...ux.intel.com>

Add a bit for the page reporting feature provided by virtio-balloon.

This patch should be replaced once the feature is added to the Linux kernel
and the bit is backported into this exported kernel header.
