Add support for Westmere to i7core_edac driver
This adds new PCI IDs for the Westmere's memory controller
devices and modifies the i7core_edac driver to be able to
probe both Nehalem and Westmere processors.
This applies to git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/i7core.git linux_next

Hmm... this hunk seems wrong to me. It ir just reverting this patch:
http://git.kernel.org/?p=linux/kernel/git/mchehab/i7core.git;a=commit;h=71753e0141a220ecbf9c71a66e0a8acce9705fb5
The other changes seem OK on my eyes.

Oops. It looks like my merge was not quite correct. It was not
intended to revert that patch, but rather change the parameters to the
function to use a struct pci_id_table instead of an int dev_id.
Here is a correct patch.

Add support for Westmere to i7core_edac driver
This adds new PCI IDs for the Westmere's memory controller
devices and modifies the i7core_edac driver to be able to
probe both Nehalem and Westmere processors.
