2019-10-03	drm/amdkfd: Eliminate get_atc_vmid_pasid_mapping_valid	Yong Zhao	1	-4/+2
	get_atc_vmid_pasid_mapping_valid() is very similar to get_atc_vmid_pasid_mapping_pasid(), so they can be merged into a new function get_atc_vmid_pasid_mapping_info() to reduce register access times. More importantly, getting the PASID and the valid bit atomically with a single read fixes some potential race conditions where the mapping changes between the two reads.

2019-10-03	drm/amdkfd: Fix NULL pointer dereference for set_scratch_backing_va()	Yong Zhao	1	-2/+0
	Currently this function pointer is missing for GFX10. Considering it is a void function since GFX9, fix it by checking the function pointer before dereferencing it.

2019-07-18	drm/amdkfd: Implement kfd2kgd_calls for Arcturus	Oak Zeng	1	-0/+83
	Arcturus shares most of the kfd2kgd_calls with gfx9. But due to SDMA register address change, it can't share SDMA related functions. Export gfx9 kfd2kgd_calls and implement SDMA related functions for Arcturus.
