Subject: [PATCH 3.12 027/111] amd64_edac: Add support for newer F16h models

From: Aravind Gopalakrishnan <Aravind.Gopalakrishnan@....com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 85a8885bd0e00569108aa7b5e26b89c752e3cd51 upstream.

Extend ECC decoding support for F16h M30h. Tested on F16h M30h with ECC
turned on using mce_amd_inj module and the patch works fine.
