Cool.

If it works for upstream, it works for me. Do you want to submit that
or prefer I do?
(If you do, could you please CC stable?)

Title:
arm64: "unsupported RELA relocation"
Status in Linaro GCC:
Unknown
Status in Linux:
Unknown
Status in gcc-5 package in Ubuntu:
Confirmed
Status in linux package in Ubuntu:
Triaged
Bug description:
linux-image-4.3.0-5-generic 4.3.0-5.16 arm64 fails to load modules
(and therefore boot). It emits messages like the following for each
attempted module load:
[ 2.156817] module libahci: unsupported RELA relocation: 275
This is reminiscent of LP: #1502946 - except that fix appears to still
be in-tact. What has changed, however, is the build environment. If I
rebuild the same kernel source in a wily chroot, it boots fine.
Marking "Confirmed" because Paulo Pisatti reported this to me, and I
reproduced.
