Merge tag 'drm-amdkfd-next-2018-05-14' of git://people.freedesktop.org/~gabbayo/linux into drm-next

This is amdkfd pull for 4.18. The major new features are:

- Add support for GFXv9 dGPUs (VEGA)
- Add support for userptr memory mapping

In addition, there are a couple of small fixes and improvements, such as:
- Fix lock handling
- Fix rollback packet in kernel kfd_queue
- Optimize kfd signal handling
- Fix CP hang in APU
