Both these patches are on my pci/sparc branch and appeared in the
Feb 19 linux-next tree.
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.
