Subject: [PATCH 3.13 30/46] powerpc/powernv: Move PHB-diag dump functions around
3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gavin Shan <shangw@...ux.vnet.ibm.com>
commit 93aef2a789778e7ec787179fc9b34ca4885a5ef3 upstream.
Prior to the completion of PCI enumeration, we actively detects
EEH errors on PCI config cycles and dump PHB diag-data if necessary.
The EEH backend also dumps PHB diag-data in case of frozen PE or
fenced PHB. However, we are using different functions to dump the
PHB diag-data for those 2 cases.
The patch merges the functions for dumping PHB diag-data to one so
that we can avoid duplicate code. Also, we never dump PHB3 diag-data
during PCI config cycles with frozen PE. The patch fixes it as well.
