Subject: [GIT PULL for v3.8] EDAC fixes and ghes-edac

Hi Linus,

Please pull from:
  git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac.git linux_next

For:
	- Some fixes at edac drivers (i7core_edac, sb_edac, i3200_edac);
	- error injection support for i5100, when EDAC debug is enabled;
	- fix edac when it is loaded builtin (early init for the subsystem);
	- a "Firmware First" EDAC driver, allowing ghes to report errors via
	  EDAC (ghes-edac).

With regards to ghes-edac, this fixes a longstanding BZ at Red Hat that
happens with Nehalem and Sandy Bridge CPUs: when both GHES and i7core_edac
or sb_edac are running, the error reports are unpredictable, as both BIOS
and OS race to access the registers. With ghes-edac, the EDAC core will
refuse to register any other concurrent memory error driver.

This patchset moves the ghes struct definitions to a separate header file
(include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to register/unregister
and to report errors via ghes-edac. Those changes were acked by ghes driver
maintainer (Huang).

Thanks!
Mauro
