Bug description:
  With the hwe-z kernel:

  ubuntu at grotian:~$ sudo modprobe libceph
  modprobe: ERROR: could not insert 'libceph': Exec format error
  ubuntu at grotian:~$ dmesg
  [66988.470307] module libceph: unsupported RELA relocation: 275

  This symptom is similar to LP: #1533009 but, in that case it impacted
  all modules, and the fix for that appears to remain in place.
