[Precise/lts-backport-quantal][CVE-2014-0131 0/3] skbuff: skb_segment: orphan frags before copying

[Luis Henriques]

Following this email I'm sending 3 patches that should fix this CVE
for Precise/lts-backport-quantal.

The actual CVE fix is the 3rd patch, which is a Ben Hutchings backport
to 3.2-3.12 kernels[1].

The other 2 patches are included as per Ben's suggestion:

 "For branches older than 3.6, this requires cherry-picking commit
  a353e0ce0fd4 ('skbuff: add an api to orphan frags').  To avoid breaking
  OOT builds of openvswitch, which will use skb_orphan_frags() if
  available, it is also necessary to cherry-pick commit dcc0fb782b3a
  ('skbuff: export skb_copy_ubufs')."
