As we track M32 segment consumption, this introduces an array to the PHB to track the mapping between M64 segment and PE number. The information is going to be used to find M64 segment from the PE number during PCI unplugging time in subsequent patches.
It would not hurt to put a few words about how we managed to live without such a mapping for M64 before but we needed mapping for M32. -- Alexey
