Hi Eric,
Missed a few things in the last reply.

If NO_DMA=y (e.g. Sun-3 all{mod,yes}-config):
drivers/iommu/dma-iommu.o: In function `iommu_dma_mmap':
dma-iommu.c:(.text+0x836): undefined reference to `dma_pgprot'
IOMMU_DMA must not be selected, unless HAS_DMA=y.
Hence fix this by making MTK_IOMMU depend on HAS_DMA.
While at it,
If CONFIG_NET_CLS_ACT=n:
net/netfilter/nft_fwd_netdev.c: In function ‘nft_fwd_netdev_eval’:
net/netfilter/nft_fwd_netdev.c:32:10: error: ‘struct sk_buff’ has no member
named ‘tc_redirected’
pkt->skb->tc_redirected = 1;
