8360e81b5d edac i5000: fix thermal issues
Make the Thermal messages (temperature got past Tmid) be displayed only
once because:

1) it's the BIOS job to configure and handle the memory throttling
2) if the BIOS is broken or is aware about the condition, flooding the
   system logs won't help anything.
3) According to the specification update for Intel 5000 MCHs, all the
   revisions of this MCH have problems on the thermal sensors, making
   not automatic (a.k.a. intelligent thermal throttling) impossible.

c066740739 edac i5000: fix error messages
Update the i5000_edac messages, making everything pass through the EDAC
(so the log controls will work) and being more specific about the errors.
Also, it makes the miscellaneous errors optional and disabled by default.

As I didn't found anywhere information about M23ERR-M26ERR
(FERR_NF_THERMAL) on FERR_NF_FBD, I'm removing them.

This adds support for the dual-core MPC8572 processor.  We have

have multiple memory controllers sharing an interrupt, flag the
interrupts with IRQF_SHARED.

Fix 443BX/GX MCH suppport in a EDAC.

It makes i82443bxgx_edac coexist with intel_agp using the same approach as
several other EDAC drivers.

10d33e9c36 edac: e752x fix too loud on nonmemory errors
This module harvests more than just memory errors, it also harvests
various bus and dma errors that the Chipset detects.  Previously, it would
report all such errors, which would cause output to be TOO loud.

This patches therefore adds a parameter which is used to turn off
NON-MEMORY error reports by default.  Or the reporting can be enabled via
the parameter

Also did code style cleanup: less than 80 characters per line rule

124682c785 edac: core fix added newline to sysfs dimm labels
The channel DIMM label does not seem to be used much in the edac code.
However, where it is used (in the core code), it is assumed to not have a
newline embedded.  This leaves the sysfs file newline free which looks
funny when cat'ing it.  Here we just add the trailing newline to the sysfs
chX_dimm_label output...

[Doug Thompson note: the DIMM label is one of the primary uses of EDAC.
User space daemon scripts, edac-utils@sourceforge, populate the DIMM label
fields, via /sys/devices/system/edac attributes, with the silk screen
labels of the motherboard in use.  dmidecode access BIOS tables, but BIOS
tables are well known to be incorrect and useless in these respects.
edac-utils will strip off any newlines before its use of the output, when
displaying DIMM slot silk screen labels.

14cc571bb1 edac: core fix to use dynamic kobject
Static kobjects are not supported in linux kernel.  Convert the
edac_pci_top_main_kobj from static to dynamic.  This avoids the double

In addition Greg KH <greg@kroah.com> has pointed out that this code may be
cleaned up significantly.  I will look at that as a follow-on patch, for
now, I just want the minimum fix to get this double-free oops bug
squashed...

Some code cleanliness issues found by Andrew Morton (thanks!) which should
not affect functionality, but which should help make the code more
maintainable.

In particular, we now:

* convert all #define's w/ a parameter to static inlines
* use 1UL rather than 1ULL when calculating an unsigned long
* use pci_disable_device

The resulting code is tested and seems to work fine...

8f421c595a edac: i5100 new intel chipset driver
Preliminary support for the Intel 5100 MCH.  CE and UE errors are reported
along with the current DIMM label information and other memory parameters.

Reasons why this is preliminary:

1) This chip has 2 independent memory controllers which, for best
   perforance, use interleaved accesses to the DDR2 memory.  This
   architecture does not map very well to the current edac data structures
   which depend on symmetric channel access to the interleaved data.
   Without core changes, the best I could do for now is to map both memory
   controllers to different csrows (first all ranks of controller 0, then
   all ranks of controller 1).  Someone much more familiar with the edac
   core than I will probably need to come up with a more general data
   structure to handle the interleaving and de-interleaving of the two
   memory controllers.

2) I have not yet tackled the de-interleaving of the rank/controller
   address space into the physical address space of the CPU.  There is
   nothing fundamentally missing, it is just ending up to be a lot of
   code, and I'd rather keep it separate for now, esp since it doesn't
   work yet...

3) The code depends on a particular i5100 chip select to DIMM mainboard
   chip select mapping.  This mapping seems obvious to me in order to
   support dual and single ranked memory, but it is not unique and DIMM
   labels could be wrong on other mainboards.  There is no way to query
   this mapping that I know of.

4) The code requires that the i5100 is in 32GB mode.  Only 4 ranks per
   controller, 2 ranks per DIMM are supported.  I do not have hardware
   (nor do I expect to have hardware anytime soon) for the 48GB (6 ranks
   per controller) mode.

5) The serial presence detect code should be broken out into a "real"
   i2c driver so that decode-dimms.pl can work.

94ee1cf5a8 edac: add e752x parameter for sysbus_parity selection
Add a module parameter "sysbus_parity" to allow forcing system bus parity
error checking on or off.  Also add support to automatically disable system
bus parity errors for processors which do not support it.

If the sysbus_parity parameter is specified, sysbus parity detection will be
forced on or off.  If it is not specified, the driver will attempt to look at
the CPU identifier string and determine if the CPU supports system bus parity.
 A blacklist was used instead of a whitelist so that system bus parity would
be enabled by default and to minimize the chances of breaking things for those
people already using the driver which for some reason have a processor that
does not have a valid CPU identifier string.

6b09ff9d78 drivers/edac: pci: broken parity regression
Using the EDAC code in kernel.org kernel version 2.6.23.8 I am seeing the
following problem:

    In the kernel there is a pci device attribute located in sysfs that is
    checked by the EDAC PCI scanning code. If that attribute is set,
    PCI parity/error scannining is skipped for that device. The attribute
    is:

            broken_parity_status

    as is located in /sys/devices/pci<XXX>/0000:XX:YY.Z directorys for
    PCI devices.

I don't think this check was actually implemented.  I have a misbehaved card
that reports a parity error every 1000 ms:

Nov 25 07:28:43 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0
Nov 25 07:28:44 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0
Nov 25 07:28:45 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0

Setting that card's broken_parity_status bit did not mask the error:

echo "1" > /sys/bus/pci/devices/0000:05:01.0/broken_parity_status

I looked through the EDAC code and did not readily see any reference to
broken_parity_status at all (which makes sense based on the behavior I am
seeing).  I applied the following patch as a proof-of-concept and now EDAC's
PCI parity error reporting behaves as documented:

Good regression find, bryan. It used to work. sigh.
I added more logic to your patch, for more coverage of the error.

48764e4143 drivers-edac: add Cell MC driver
Adds driver for the Cell memory controller when used without a Hypervisor such
as on the IBM Cell blades.  There might still be some improvements to do to
this such as finding if it's possible to properly obtain more details about
the address of the error but it's good enough already to report CE counts
which is our main priority at the moment.

af5ca3f4ec Driver core: change sysdev classes to use dynamic kobject names
All kobjects require a dynamically allocated name now. We no longer
need to keep track if the name is statically assigned, we can just
unconditionally free() all kobject names on cleanup.

3514faca19 kobject: remove struct kobj_type from struct kset
We don't need a "default" ktype for a kset.  We should set this
explicitly every time for each kset.  This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.

This patch is based on a lot of help from Kay Sievers.

Nasty bug in the block code was found by Dave Young
