I've cross compiled the kernel+modules, mostly following the steps in comment #18.

Then, I've scanned the generated module for the AARCH64_ADR_PREL_PG_HI21 relocation.

When compiled with Linaro-2015.12, this relocation is present.
When compiled with Linaro-2015.10, it is not.
When using Linaro-2015.11, the build fails with errors such as:
Assembler messages:
Error: selected processor does not support `aese v0.16b,v1.16b'

Assuming that these relocations are the real cause of the problem, I'm going to bisect to identify which commit in our branch introduced them.
