Ok I managed to miss these ones somehow, apologies. This series can be
squashed into the initial series but there is also Linus' fix for faraday
to address:
https://patchwork.ozlabs.org/patch/778999/
I can respin a v3 but I am off the radar next week so timing for the
pci_fixup_irqs() removal looks bad, I am not sure what's the next course
of action but I think it is better to drop it for this cycle and wait
for 4.14 (hopefully there are not many PCI host bridges updates to
rebase but I will cope with that anyway - that's the best I can do).
Thanks,
Lorenzo
