Hi Linus !

Here is a series of powerpc fixes. It's a bit big, mostly because of the
series of 11 "EEH" patches from Gavin. The EEH (Our IBM specific
PCI/PCIe Enhanced Error Handling) code had been rotting for a while and
this merge window saw a significant rework & fixing of it by Gavin Shan.

However, that wasn't complete and left some open issues. There were
still a few corner cases that didn't work properly, for example in
relation to hotplug and devices without explicit error handlers. We had
some patches but they weren't quite good enough yet so I left them off
the 3.11 merge window.

Gavin since then fixed it all up, we ran quite a few rounds of testing
and it seems fairly solid (at least probably more than it has ever
been). This should probably have made -rc1 but both Gavin and I took
some vacation so it had to wait for -rc2.

The rest is more bug fixes, mostly to new features recently added, for
example, we missed the cpu table entry for one of the two models of P8
(we didn't realize they had different PVR [Processor Version Register]
values), some module CRC issues, etc...

Please apply,

Cheers,
Ben.
