void callback

eeh_pe_traverse - Traverse PEs in the specified PHB : root PE

: extra parameter to callback

The function is used to traverse the specified PE and its child PEs. The traversing is to be terminated once the callback returns something other than NULL, or no more PEs to be traversed.

eeh_pe_dev_traverse - Traverse the devices from the PE : EEH PE

: extra parameter to callback

The function is used to traverse the devices of the specified PE and its child PEs.
