Yes. That's ugly :/
I would prefer to address this issue after the cleanup provided
by the patchset adding an IRQ domain for IPIs.
http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=228762
Most of the mess comes from the XIVE IPI HW IRQ number which
hijacks IRQ number 0. It should be easier after this is fixed.
Thanks,
C.
