[0/5] Netfilter fixes for net-next

Hi David,

This is a pull request to address fallout from previous nf-next pull
request, only fixes going on here:

1) Address a potential null dereference in nf_unregister_net_hook()
   when becomes nf_hook_entry_head is NULL, from Aaron Conole.

2) Missing ifdef for CONFIG_NETFILTER_INGRESS, also from Aaron.

3) Fix linking problems in xt_hashlimit in x86_32, from Pai.

4) Fix permissions of nf_log sysctl from unpriviledge netns, from
   Jann Horn.

5) Fix possible divide by zero in nft_limit, from Liping Zhang.

You can pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next.git

P.S: Sorry for not addressing this any sooner, a mixture of traveling
overhead, conference and problems with wifi connection has prevented me
to do this any sooner.

Thanks!
