From 9a43996524dacb19f9e90484190253873748bd1f Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Mon, 4 Nov 2013 16:32:46 +0800 Subject: [PATCH] powerpc/powernv: Add PE to its own PELTV commit 631ad691b5818291d89af9be607d2fe40be0886e upstream. We need add PE to its own PELTV. Otherwise, the errors originated from the PE might contribute to other PEs. In the result, we can't clear up the error successfully even we're checking and clearing errors during access to PCI config space.
