Bug description:
  This upstream patch "arm64: errata: add module build workaround for
  erratum #843419" breaks module loading on arm64 and was pulled into
  trusty-proposed via stable release. The trusty master-next commit is:
  f869de1cf9b57d28dbba9f15569f5ae2c54c8724. Wily saw this as well, since
  it also carries the patch and the workaround used there was to disable
  CONFIG_ARM64_ERRATUM_843419.

  The issue was mentioned to upstream here:
  http://www.spinics.net/lists/arm-kernel/msg449982.html
  and a fix was proposed here: 
  http://www.spinics.net/lists/arm-kernel/msg450685.html
