[PATCH 0/6] EEH Cleanup

[Gavin Shan]

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.
