I think once you've removed the midlayer in the previous patch it would
makes sense to merge the 2 patches into 1.
ok, will squash the two
Bunch more comments below.

[PATCH 7/9] drm/xen-front: Implement KMS/connector handling
From: Oleksandr Andrushchenko
Implement kernel modesetiing/connector handling using
DRM simple KMS helper pipeline:
- implement KMS part of the driver with the help of DRM
simple pipepline helper which is possible due to the fact
that the para-virtualized driver only supports a single
(primary) plane:
- initialize connectors according to XenStore configuration
- handle frame done events from the backend
- generate vblank events
- create and destroy frame buffers and propagate those
to the backend
- propagate set/reset mode configuration to the backend on display
enable/disable callbacks
- send page flip request to the backend and implement logic for
reporting backend IO errors on prepare fb callback
- implement virtual connector handling:
- support only pixel formats suitable for single plane modes
- make sure the connector is always connected
- support a single video mode as per para-virtualized driver
configuration
