[PATCH 0/22] ppc64: Full sequence of PCI Error recovery patches

The following sequence of patches implement the full set of PCI error recovery functions for ppc64. There are a large numer of patches because I've attempted to keep the scope of each patch reasonably small, and thus easy to review. (The system should remain usable and functional after applying each patch).

A detailed explanation of what this is and how it works is in patch 6/22; if you don't already know what this is about, that would be the place to start reading.

These patches result in systems that have survived multi-hour runs with thousands of PCI errors injected. Although this is good, I still can't warrent that this is bug-free, as there are still hardware combos that haven't been tested. But for now, it seems to work.
