Hello dann, or anyone else affected,
Accepted gcc-5 into xenial-proposed. The package will build now and be
available at

few hours, and then in the -proposed repository.
Please help us by testing this new package. See
** Description changed:
+ [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.

arm64: "unsupported RELA relocation: 275" loading certain modules
Status in Linux:
In Progress
Here's a backport of the gcc-6 fix to gcc-5. It includes a backport of
the -mpc-relative-literal-loads option rename change, since it was a
dependent patch, and I'm not comfortable enough w/ gcc development to do
the backport w/o it.

arm64: "unsupported RELA relocation: 275"
I attempted to port the above patch to our branch to test it, but it has
conflicts with the linaro snapshot patch we apply. It appears that the
conflicts are with a backport of r237607[*] applied to Linaro's gcc-6
branch. r237607 is also supposed to be the source of the patch in
Comment #4 - so

arm64: "unsupported RELA relocation: 275"
Hi,
I think the problem has already been solved here:
https://gcc.gnu.org/ml/gcc-patches/2017-01/msg00736.html
This fix appeared to do the trick for gcc-6_1_0-release on my machine, I
would suggest that you give it a go.
[ I verified the relocations via:
aarch64-linux-gnu-objdump -dr
Attached is a buildlog of the kernel w/ V=1 set to see the full gcc commandline.
I confirmed that the symptoms are present w/ this build.
