Hi all,

After merging the bfp-next tree, today's linux-next build (x86_64
allmodconfig ) failed like this:

ERROR: modpost: "cnum64_umin" [drivers/net/ethernet/netronome/nfp/nfp.ko] undefined!
ERROR: modpost: "cnum64_umax" [drivers/net/ethernet/netronome/nfp/nfp.ko] undefined!

Caused by commit

b93f7180f0bc ("bpf: use accessor functions for bpf_reg_state min/max fields")

It looks like the issue here is that these new accessor functions are not
exported symbols and therefore can't be used by a driver that is built as
a module.

I've used the previous tree for today's linux-next.

Thanks,
Thierry
