Bug description:
[Impact]
Certain kernel modules are unloadable (libceph & scsi_debug) due to the
compiler generating unsupported relocations.
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.
[Test Case]
With the hwe-z kernel:
ubuntu@grotian:~$ sudo modprobe libceph
modprobe: ERROR: could not insert 'libceph': Exec format error
ubuntu@grotian:~$ dmesg
[66988.470307] module libceph: unsupported RELA relocation: 275
[Regression Risk]
The scope of the fix is restricted to aarch64, so regressions should only
impact the arm64 port of Ubuntu. Regressions could impact when literal loads
are used - which may have performance impacts or possibly cause software to
fail to build/run where it previously did. This is somewhat mitigated by the
fact that this has been fixed in artful gcc-5/gcc-6 and used on our buildds for
some time. Only "somewhat", because gcc-7 is now the default.
