From: Gavin Shan <hidden>
Date: 2012-06-27 16:17:56
Subsystem:
linux for powerpc (32-bit and 64-bit), pci enhanced error handling (eeh) for powerpc, the rest · Maintainers:
Madhavan Srinivasan, Mahesh J Salgaonkar, Linus Torvalds
The patch adds more logs to EEH initialization functions for
debugging purpose. Also, the machine type ("pSeries") is checked
in the platform initialization to assure it's the correct platform
to invoke it.
