+	bool "EDAC (Error Detection And Correction) reporting"
+	depends on HAS_IOMEM
+	depends on X86 || PPC || TILE || ARM || EDAC_SUPPORT
+	help
+	  EDAC is designed to report errors in the core system.
+	  These are low-level errors that are reported in the CPU or
+	  supporting chipset or other subsystems:
+	  memory errors, cache errors, PCI errors, thermal throttling, etc..
+	  If unsure, select 'Y'.
+
+	  If this code is reporting problems on your system, please
+	  see the EDAC project web pages for more information at:
+
+	  <http://bluesmoke.sourceforge.net/>
+
+	  and:
+
+	  <http://buttersideup.com/edacwiki>
+
+	  There is also a mailing list for the EDAC project, which can
+	  be found via the sourceforge page.

+config EDAC_LEGACY_SYSFS
+	bool "EDAC legacy sysfs"
+	default y
+	help
+	  Enable the compatibility sysfs nodes.
+	  Use 'Y' if your edac utilities aren't ported to work with the newer
+	  structures.
+
+config EDAC_DEBUG
+	bool "Debugging"
+	help
+	  This turns on debugging information for the entire EDAC subsystem.
+	  You do so by inserting edac_module with "edac_debug_level=x." Valid
+	  levels are 0-4 (from low to high) and by default it is set to 2.
+	  Usually you should select 'N' here.
+
+config EDAC_DECODE_MCE
+	tristate "Decode MCEs in human-readable form (only on AMD for now)"
+	depends on CPU_SUP_AMD && X86_MCE_AMD
+	default y
+	---help---
+	  Enable this option if you want to decode Machine Check Exceptions
+	  occurring on your machine in human-readable form.
+
+	  You should definitely say Y here in case you want to decode MCEs
+	  which occur really early upon boot, before the module infrastructure
+	  has been initialized.

+config EDAC_MCE_INJ
+	tristate "Simple MCE injection interface"

+	  aspects of the MCE handling code.

+
+config EDAC_MM_EDAC
+	tristate "Main Memory EDAC (Error Detection And Correction) reporting"
+	select RAS
+	help
+	  Some systems are able to detect and correct errors in main
+	  memory.  EDAC can report statistics on memory error
+	  detection and correction (EDAC - or commonly referred to ECC
+	  errors).  EDAC will also try to decode where these errors
+	  occurred so that a particular failing memory module can be
+	  replaced.  If unsure, select 'Y'.
+
+config EDAC_GHES
+	bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
+	depends on ACPI_APEI_GHES && (EDAC_MM_EDAC=y)
+	default y
+	help
+	  Not all machines support hardware-driven error report. Some of those
+	  provide a BIOS-driven error report mechanism via ACPI, using the
+	  APEI/GHES driver. By enabling this option, the error reports provided
+	  by GHES are sent to userspace via the EDAC API.
+
+	  When this option is enabled, it will disable the hardware-driven
+	  mechanisms, if a GHES BIOS is detected, entering into the
+	  "Firmware First" mode.
+
+	  It should be noticed that keeping both GHES and a hardware-driven
+	  error mechanism won't work well, as BIOS will race with OS, while
+	  reading the error registers. So, if you want to not use "Firmware
+	  first" GHES error mechanism, you should disable GHES either at
+	  compilation time or by passing "ghes.disable=1" Kernel parameter
+	  at boot time.
+
+	  In doubt, say 'Y'.

+config EDAC_AMD64_ERROR_INJECTION
+	bool "Sysfs HW Error injection facilities"
+	depends on EDAC_AMD64
+	help
+	  Recent Opterons (Family 10h and later) provide for Memory Error
+	  Injection into the ECC detection circuits. The amd64_edac module
+	  allows the operator/user to inject Uncorrectable and Correctable
+	  errors into DRAM.
+
+	  When enabled, in each of the respective memory controller directories
+	  (/sys/devices/system/edac/mc/mcX), there are 3 input files:
+
+	  - inject_section (0..3, 16-byte section of 64-byte cacheline),
+	  - inject_word (0..8, 16-bit word of 16-byte section),
+	  - inject_ecc_vector (hex ecc vector: select bits of inject word)
+
+	  In addition, there are two control files, inject_read and inject_write,
+	  which trigger the DRAM ECC Read and Write respectively.
