[PATCH] PPC64: draft version of EEH code.

[Benjamin Herrenschmidt]

Ok, built your stuff, applied, setup a partition on an SF2 with an
ethernet e100 card in a hotplug slot, got the errinj tools (0.8.5),
enabled error injection in the FSP, rebooted the partition, and then
did:

linux:~ # /opt/ibmras/errinjct eeh -f 0 -p U7311.D20.10488BA-P1-C02-T1
Injecting an ioa-bus-error...

Looks like it died in RTAS or something weird like that ...
