I can repro a powerpc build failure with ice, but I don't see anything wrong in mlx5 in an allmodconfig. The config you attached is invalid: .config:709:warning: symbol value 'm' invalid for HOTPLUG_PCI_SHPC .config:892:warning: symbol value 'm' invalid for NF_CT_PROTO_GRE .config:919:warning: symbol value 'm' invalid for NF_NAT_REDIRECT .config:922:warning: symbol value 'm' invalid for NF_TABLES_INET .config:1099:warning: symbol value 'm' invalid for NF_TABLES_IPV4 .config:1104:warning: symbol value 'm' invalid for NF_TABLES_ARP .config:1146:warning: symbol value 'm' invalid for NF_TABLES_IPV6 .config:1537:warning: symbol value 'm' invalid for NET_DEVLINK .config:2721:warning: symbol value 'm' invalid for ISDN_CAPI .config:3066:warning: symbol value 'm' invalid for HW_RANDOM_TPM .config:3589:warning: symbol value 'm' invalid for LIRC .config:5356:warning: symbol value 'm' invalid for FS_ENCRYPTION I'll send a fix based on your error messages, it does look like en_main.c should include filter.h.
