Subject: CVE requests - kernel network vulns

1) gre: fix netns vs proto registration ordering

"GRE protocol receive hook can be called right after protocol addition 
is done. If netns stuff is not yet initialized, we're going to oops in

This is remotely oopsable if ip_gre is compiled as module and packet
comes at unfortunate moment of module loading."

2) tunnels: fix netns vs proto registration ordering

"Same stuff as in ip_gre patch: receive hook can be called before netns
setup is done, oopsing in net_generic()."

Thanks, Eugene
