Hi:

Boot of an 8-socket T5 sparc system fails on top of tree. git bisect 
points to this commit:

sparc/PCI: Clip bridge windows to fit in upstream windows

Every PCI-PCI bridge window should fit inside an upstream bridge window 
because orphaned address space is unreachable from the primary side of 
the upstream bridge.  If we inherit invalid bridge windows that overlap 
an upstream window from firmware, clip them to fit and update the bridge 
accordingly.


Sure enough if I revert it on top of tree the system boots fine.
