Ah, that explains why kzm9g-legacy didn't explode in -next...

Hi Marc,
I believe that is in progress.
As I understand things the plan is to move away from this when
multiplatform support for the r8a7740 and the Armadillo800-EVM board are
complete. And thus we can remove legacy-C support for that SoC and board.
Lots of deletions!
Geert,
can I confirm that you would like me to pick this up - there are a lot of
changes flying around at the moment? If so would you like it considered as
a fix for v3.19 and stable? If so I will need some information about what
patch introduced the problem in which release. If not can you state why?
The reason for requesting such information is so that I can pass it on to
the ARM SoC maintainers so it is clear to them how to handle the patch and
why.

The above-mentioned commit will be in v3.19-rc1. So getting it in
v3.19 only sounds
fine (unless you want to backport the IRQ domain breakage to 3.14-ltsi ;-)
