Subject[PATCH net-next 2/2] net: fix building errors on powerpc when CONFIG_RETPOLINE is not set
From
This commit fixes the errores reported when building for powerpc:

ERROR: modpost: "ip6_dst_check" [vmlinux] is a static EXPORT_SYMBOL
ERROR: modpost: "ipv4_dst_check" [vmlinux] is a static EXPORT_SYMBOL
ERROR: modpost: "ipv4_mtu" [vmlinux] is a static EXPORT_SYMBOL
ERROR: modpost: "ip6_mtu" [vmlinux] is a static EXPORT_SYMBOL

Fixes: f67fbeaebdc0 ("net: use indirect call helpers for dst_mtu")
Fixes: bbd807dfbf20 ("net: indirect call helpers for ipv4/ipv6 dst_check functions")
