Yes this was expected. this series needs to be applied on part 1: [PATCH
v6 0/7] KVM PCIe/MSI passthrough on ARM/ARM64: kernel part 1/3: iommu
changes, https://lkml.org/lkml/2016/4/4/90.

Same for part 3.

I split the whole series to ease the review process however this comes
at the expense of automatic testing. Sorry for that.

Best Regards

Eric
