linux-next: manual merge of the drm tree with Linus' tree

Hi Dave,

Today's linux-next merge of the drm tree got conflicts in
drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c and
drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.h between commits
b8cbab042cd6 ("drm/amdkfd: Allow user to limit only queues per device")
and 9fa843e76d90 ("drm/amdkfd: Fix bug in call to init_pipelines()")
from Linus' tree and commits bcea30817574 ("drm/amdkfd: Add SDMA
user-mode queues support to QCM") and fe502804205e ("drm/amdkfd: Remove
call to deprecated init_memory interface") from the drm tree.

I fixed it up (hopefully - see below) and can carry the fix as
necessary (no action is required).
