That is what I was most concerned about :-(. Unfortunately, it
affects many of the most widely used arm qemu emulations, so it
would be very desirable to get this fixed, either in the kernel
or in qemu.

See https://github.com/groeck/linux-build-test, specifically
https://github.com/groeck/linux-build-test/tree/master/rootfs/arm/.
run-qemu-arm.sh includes the various command lines and configurations.

Note that some of the tests require a patched version of qemu.
The tests failing above should all work with the latest published
version of qemu (2.4), though.

Please let me know if there is anything I can do to help tracking
this down.

Thanks,
Guenter
