Confirmation: Kernel 3.10.77-rc2 builds for the target (a dockstar), and the system boots up without visible regressions. About the possible fix I suggested: The mentioned commit applies for include/linux/irq.h only but I still consider it way too intrusive to judge whether this is sufficient or will introduce other problems. So I'll happily leave this to people who have deeper knowledge of that field, I don't.
