[PATCH V3 0/3] libxl: Make grants configurable for virtio devices

[Viresh Kumar <viresh.kumar@linaro.org>]

Hi,

This patchset intends to make grant mapping usage configurable for virtio
devices. Currently they are forced enabled for backends running on non-Dom0
domains. This patchset adds a new `grant_usage` parameter for the virtio
devices, which can be used to enable or disable grant mappings irrespective of
the backend domain, while still preserving the default behavior in absence of a
parameter.

V2->V3:
- Patch 2/3 is new and fixes ordering issues with default values.
- Reuse `libxl_defbool` instead of defining a new type, it can take values 0 and
  1.
- Improved commit logs and comments.

V1->V2:
- Instead of just 0 or 1, the argument can take multiple values now and control
  the functionality in a better way.

- Update .gen.go files as well.

- Don't add nodes under frontend path.

Viresh Kumar (3):
  libxl: virtio: Remove unused frontend nodes
  libxl: Call libxl__virtio_devtype.set_default() early enough
  libxl: arm: Add grant_usage parameter for virtio devices
