commit 680174cfd1e1cea70a8f30ccb44d8fbdf996018e upstream.
After fixing nested FPU contexts caused by 41401ac67791 we're still seeing complaints about spurious kernel_fpu_end(). As it turns out this was already fixed for dcn20 in commit f41ed88cbd ("drm/amdgpu/display: use GFP_ATOMIC in dcn20_validate_bandwidth_internal") but never moved forward to dcn21.
