From c533b46cc7da58e5ccbd20ac2f607ff60d24eb4e Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Fri, 7 Sep 2012 22:44:11 +0000 Subject: [PATCH] powerpc/eeh: Build EEH event based on PE The original implementation builds EEH event based on EEH device. We already had dedicated struct to depict PE. It's reasonable to build EEH event based on PE.
