[SPARC32]: Fix over-optimization by GCC near ip_fast_csum. In some cases such as: iph->check = 0; iph->check = ip_fast_csum((unsigned char *)iph, iph->ihl); GCC may optimize out the previous store. Observed as a failure of NFS over udp (bad checksums on ip fragments) when compiled with GCC 3.4.2. Signed-off-by: Bob Breuer <breuerr@mc.net> Signed-off-by: David S. Miller <davem@davemloft.net>
