    xtensa:allmodconfig fails to build with the following errors.
    
    drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c:
    	In function ‘gk20a_instobj_dtor_dma’:
    drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c:154:2: error:
    	implicit declaration of function ‘dma_free_attrs’
    drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c:
    	In function ‘gk20a_instobj_ctor_dma’:
    drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c:218:2: error:
    	implicit declaration of function ‘dma_alloc_attrs’
    
    Xtensa does not provide those functions at this time.
    Provide dummy implementations to avoid build errors.
