Export statistics for successful and failed huge page allocations
from the virtio balloon driver. These 2 stats come directly from
the vm_events HTLB_BUDDY_PGALLOC and HTLB_BUDDY_PGALLOC_FAIL.

It's too late now. In future if you want the patches to be squashed

No. If any of those tests fail, we want to stop dead. They'll lead to
horrendous bugs throughout the kernel if they're wrong.

This patch addresses the issues that were seen with the 3 netdev model by
avoiding the creation of an additional netdev. Instead the bypass state
information is tracked in the original netdev and a different set of
ndo_ops and ethtool_ops are used when BACKUP feature is enabled.

This patch enables virtio_net to switch over to a VF datapath when a VF
netdev is present with the same MAC address. It allows live migration
of a VM with a direct attached VF without the need to setup a bond/team
between a VF and virtio net device in the guest.
The hypervisor needs to enable only
This feature bit can be used by hypervisor to indicate virtio_net device to
act as a backup for another device with the same MAC address.
VIRTIO_NET_F_BACKUP is defined as bit 62 as it is a device feature bit.

Patch 1 introduces a new feature bit VIRTIO_NET_F_BACKUP that can be
used by hypervisor to indicate that virtio_net interface should act as
a backup for another device with the same MAC address.
Ppatch 2 is in response to the community request for a 3 netdev
solution. However, it creates some iss

qxl_io_log() sends messages over to the host (qemu) for logging.
Remove the function and all callers, we can just use standard
DRM_DEBUG calls (and if needed a serial console).

The encoder callbacks are only called in case the video mode changes.
So any layout changes without mode changes will go unnoticed.
Add qxl_crtc_update_monitors_config(), based on the old
qxl_write_monitors_config_for_encoder() function. Hook it into the
enable, disable and flush atomic crtc call
Needed to avoid a forward declaration in a followup patch.
Pure code move, no functional change.

These days drm core checks function pointers everywhere before calling
them. So we can drop a bunch of dummy functions now.

Should be doable.
I'm wondering two things though:
(1) Will shmem actually help avoiding a copy?
virtio-gpu with virgl will (even if the guest doesn
