My take is that JC's aim is to get this four patch series reviewed and merged (which is *not* sufficient to get ACPI PCI to work fully on ARM64 - see cover letter - the remaining patches in his branch are not fixes, it is code that is required to get things to work, these 4 patches stand alone are not sufficient but I understand he wants to get them reviewed following feedback on the lists) so that we can make progress on ACPI PCI on ARM64. I will comment on the patches as soon as I have time to review them, I certainly would like to understand what we have to do with the rest of the code though (provided this series is good to go) see above.
