Building for ARCH=um with W=1 C=1 makes sparse report "incompatible types in comparison expression (different address spaces)" warnings in the KFD code, exposed after UML builds were enabled: - amdgpu_amdkfd_fence.c compares the __rcu-annotated dma_fence.ops pointer directly in to_amdgpu_amdkfd_fence(). - amdgpu_amdkfd_gpuvm.c compares the __rcu eviction fence pointer directly in amdgpu_amdkfd_gpuvm_restore_process_bos().
