This series introduces a way to track memory used by balloon drivers.
Add a NR_BALLOON_PAGES counter to track how many pages are reclaimed by the
balloon drivers. First add the accounting, then updates the balloon drivers
(virtio, Hyper-V, VMware, and Xen) to maintain this counter.
This makes the

According to GDMA protocol, holes (zeros) are allowed at the beginning
or middle of the gdma_list_devices_resp message. The existing code
cannot properly handle this, and may miss some devices in the list.
To fix, scan the entire list until the num_of_devs are found, or until
the end of the list.

When on a MANA VM hibernation is triggered, as part of hibernate_snapshot(),
mana_gd_suspend() and mana_gd_resume() are called. If during this
mana_gd_resume(), a failure occurs with HWC creation, mana_port_debugfs
