[GIT PULL] pstore/ram for 3.11

From: Rob Herring
Date: Wed Jun 12 2013 - 23:44:51 EST

Not sure who takes this, but please pull these 2 changes for pstore for
3.11. These are necessary to get pstore to work with on-chip RAM on
Calxeda highbank platform.

I dropped the write-combine change from this series. While write-combine
is technically the correct mapping needed for ARM, it doesn't solve any
problem for me.


The following changes since commit c7788792a5e7b0d5d7f96d0766b4cb6112d47d75:

Linux 3.10-rc2 (2013-05-20 14:37:38 -0700)
