I've been trying to get what's essentially the same patch merged since
before the 4.8 merge window. I would be more understanding if this
were something new that's not upstream, but broken support for the
hardware (that, from a user perspective, is a bug, since they can
select the target but then it doesn't boot) has already been in one
release due to missing core drivers, and the irq patches have already
been merged in this release (post-rc1 even).
