The patchset is EEH cleanup and expected to be merged during 3.17
window. The the patchset is expected to be applied after:
| EEH support for guest
| 2 more bug fixes for EEH support for guest
| M64 related EEH changes
| 2 bug fixes from Mike Qiu
|
+-> The current patchset
Except the following 2 patches, all patches are for cleanup:
Refactoring EEH log, replacing pr_warning() with pr_warn(),
reducing length of EEH log dump etc:
PATCH[2/6]: We have to enable I/O path before collecting EEH log.
Otherwise, 0xFF is always returned from PCI config
of devices in frozen PE. the problem is only existing
on PHB3.
PATCH[6/6]: It's something related to EEH guest log retrieval.
Currently, all PEs in one specific PHB are sharing
diag-data blob for storing EEH log. It's possible
for diag-data blob overwritten before being collected
by guest. The patch introduce auxillary data for PE,
which is maintained by backend. On PowerNV, that's used
for EEH log.
