I also had to edit the patch for linebreaks etc :)

Anyways... when I apply the patch and try too compile, I get:

net/ipv6/addrconf.c: In function 'addrconf_disable_ipv6':
net/ipv6/addrconf.c:4029: error: implicit declaration of function 'restart_syscall'
make[2]: *** [net/ipv6/addrconf.o] Error 1
make[1]: *** [net/ipv6] Error 2


The relevant line is pointed out (->) below:

----
   static int addrconf_disable_ipv6(struct ctl_table *table, int *p, int old)
   {
           struct net *net;
   
           net = (struct net *)table->extra2;
   
           if (p == &net->ipv6.devconf_dflt->disable_ipv6)
                   return 0;
   
           if (!rtnl_trylock())
->                 return restart_syscall();
   
           if (p == &net->ipv6.devconf_all->disable_ipv6) {
                   __s32 newf = net->ipv6.devconf_all->disable_ipv6;
                   net->ipv6.devconf_dflt->disable_ipv6 = newf;
                   addrconf_disable_change(net, newf);
           } else if ((!*p) ^ (!old))
                   dev_disable_change((struct inet6_dev *)table->extra1);
   
           rtnl_unlock();
           return 0;
   }

For what it's worth, I'm using gcc 4.3.3.
