Any testing and feedback (especially on the second patch, which should change /proc/iomem) would be great. They're headed for v4.17 unless I hear about issues. It would be useful to hear about what's still broken so I can try to pull in the other patches. IIUC, the first patch should fix something on T4. I think patch 04/13 of the original series adds IORESOURCE_MEM_64 to host bridge windows. We don't do that for other arches, so it's not clear to me why we need it for sparc. Patch 09/13 of the original series fixes something on T5-8. I haven't included that yet, so it's probably still broken. Bjorn
