  [arm64] nova instances can't boot with 3.13.0-92

Bug description:

  It would appear that arm64 nova instances can't boot on 3.13.0-92.

  The serial console displays :

  error: plain Image kernel not supported - rebuild with CONFIG_(U)EFI_STUB 
  unaligned pointer 0xb90002e058000c57
  Aborted. Press any key to exit.

  I suspect this is due to LP#1566221, more specifically :
     * [Config] CONFIG_EFI=n for arm64

  This is pretty serious. I'm not 100% sure the above is the cause, but
  if so, it should be reverted asap.

  Thank you.
