Hi,

Please find the patch set that implements FSP memory error handling and
plumbs then into memory poison infrastructure.

Patch 1 enables the generic memory hwpoisoning infrastructure for ppc64.
Patch 2 reads the memory errors reported from opal layer and plumbs them
into memory poison infrastructure.

This patch uses new messaging channel infrastructure (proposed through a
separate patch at
https://lists.ozlabs.org/pipermail/linuxppc-dev/2013-November/113331.html)
to pull the fsp memory errors to linux.

Thanks,
-Mahesh.
