[PATCH v2 0/2] Fix a pair of setup bus bugs.

[Logan Gunthorpe]

Hey,

This is largely a resend to get some more attention. I've attempted to clean
up and expand on the commit message of the first commit because the
bug is a bit of a nightmare to explain and follow. There's a lot more
information on the first commit in the original thread here[1] including
instructions on how to reproduce it in QEMU.

The second patch fixes an unrelated bug, with similar symptoms, in
the same code. It was a lot easier to debug and the reasoning should
hopefully be easier to follow, but I don't think it was reviewed much
during the first posting due to the nightmare in the first patch.

Thanks,

Logan
