commit e2884fe84a83c562346eb9d92783a3576ce67177 upstream.
Commit c103a23f2f29 ("drm/amd: Convert amdgpu to use suballocation helper.") made the fence wait in amdgpu_sa_bo_new() interruptible but there is no code to handle an interrupt. This caused the kernel to randomly explode in high-VRAM-pressure situations so make it uninterruptible again.
