Yes, it's nft_concat_range.sh caused this error.

```

[  165.249447] # selftests: netfilter: nft_concat_range.sh
[  165.249453]
[  165.295336] # TEST: reported issues
[  165.295342]
[  165.316525] BUG: using smp_processor_id() in preemptible [00000000]
code: nft/6247
[  165.319547] caller is nft_pipapo_insert+0x464/0x610 [nf_tables]

5.6.0-rc5-01595-ge32a4dc6512ce3 #1

```


And i think this error is caused by some kconfigs.

This test was passed until we enabled all kconfigs defined in
netfilter/config. :-(
