[PATCH] 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.
