Pull EDAC updates from Borislav Petkov:
"Following up on last week's discussion, here's my part of the EDAC
pile, highlights in the signed tag.
The last two patches have a date from just now because I've just
applied them to the tree after Johannes sent them to me earlier. I
decided to forward them now because they're trivial.
There's a third one for MPC85xx which adds PCIe error interrupt
support but since it is not so trivial and hasn't seen any linux-next
time, I'm deferring it to 3.14
EDAC update highlights:
- Support for Calxeda ECX-2000 memory controller, from Robert Richter
- Misc Calxeda Highbank drivers and EDAC core cleanups, from Rob
Herring and Robert Richter
- New maintainer for Freescale's MPC85xx EDAC driver: Johannes
Thumshirn"
