can you put this one in ?
https://patchwork.kernel.org/patch/2647131/

[v5,1/7] PCI: Don't let mmio fallback to must-only, if ioport fails
with must+optional


it will not just help powerpc case.
also found that it is needed for one of 8 socket system that support pciehp
but some root bus does not have ioport range allocated.
in that case sriov does not work.

Thanks

Yinghai

OK, I'll merge [1/7] if you open a kernel.org bugzilla and attach logs
showing the SR-IOV issue you tripped over.  Patch [1/7] will
immediately fix that bug, of course.  If anybody ever reworks our
resource assignment code, it will help to have information about the
scenarios it has to happen.

Actually, your patch should also have a reference to Ben's problem
report.  But I can dig that out and add it for you.
