Hi Linus !

We discovered some breakage in our "EEH" (PCI Error Handling) code while
doing error injection, due to a couple of regressions. One of them is
due to a patch (37f02195b) that, in hindsight, I shouldn't have merged
considering that it caused more problems than it solved.

Please pull those two fixes. One for a simple EEH address cache
initialization issue. The other one is a patch from Guenter that I had
originally planned to put in 3.11 but which happens to also fix that
other regression (a kernel oops during EEH error handling and possibly
hotplug).

With those two, the couple of test machines I've hammered with error
injection are remaining up now. EEH appears to still fail to recover on
some devices, so there is another problem that Gavin is looking into but
at least it's no longer crashing the kernel.

Cheers,
Ben.
