undefined "csum_ipv6_magic" in net/ipv6/netfilter/nf_conntrack_ipv6.ko

Hi All,

The asm/arch-ppc/checksum.h doesn't provide an optimizied version of `csum_ipv6_magic'. You shoud use a generic version.

During build on PPC32 I get:

CC [M] net/ipv6/netfilter/nf_conntrack_proto_icmpv6.o
net/ipv6/netfilter/nf_conntrack_proto_icmpv6.c: In function `icmpv6_error':
net/ipv6/netfilter/nf_conntrack_proto_icmpv6.c:239:
warning: implicit declaration of function csum_ipv6_magic'

And finally get unusable module:
* Warning: "csum_ipv6_magic" [net/ipv6/netfilter/nf_conntrack_ipv6.ko] undefined!

Problem was also reported in bug#307.

Regards,
Pawel.
