The series is split from "[PATCH v8 00/45] powerpc/powernv: PCI hotplug
support". The series does couple of things as below. The patches are
required to support PCI hotplug on PowerNV platforms. However, the
patches refactor the code with the goal: not affecting current logic.
* Code cleanup and refactoring.
* Track IO/M32/M64 segments consumed by one particular PE.
* Remove DMA32 list and improve DMA32 segment tracking.
* M64 support for IODA1 so that we have unified basis for the
subsequent patches to support PCI hotplug.
* Couple of fixes to PCI hotplug (used by EEH).
* Exported functions to be used by PCI hotplug.
