commit 75135da0d6 upstream.
pci_get_device() decrements the reference count of "from" (last
argument) so when we break off the loop successfully we have only one
device reference - and we don't know which device we have. If we want
a reference to each device, we must take them explicitly and let
the pci_get_device() walk complete to avoid duplicate references.
This is serious, as over-putting device references will cause
the device to eventually disappear. Without this fix, the kernel
crashes after a few insmod/rmmod cycles.
Tested on an Intel S7000FC4UR system with a 7300 chipset.

commit c0f5eeed0f upstream.
The reference count changes done by pci_get_device can be a little
misleading when the usage diverges from the most common scheme. The
reference count of the device passed as the last parameter is always
decreased, even if the function returns no new device. So if we are
going to try alternative device IDs, we must manually increment the
device reference count before each retry. If we don't, we end up
decreasing the reference count, and after a few modprobe/rmmod cycles
the PCI devices will vanish.
In other words and as Alan put it: without this fix the EDAC code
corrupts the PCI device list.

commit f0a56c4801 upstream.
It can happen that configurations are running in a single-channel mode
even with a dual-channel memory controller, by, say, putting the DIMMs
only on the one channel and leaving the other empty. This causes a
problem in init_csrows which implicitly assumes that when the second
channel is enabled, i.e. channel 1, the struct dimm hierarchy will be
present. Which is not.
So always allocate two channels unconditionally.
This provides for the nice side effect that the data structures are
initialized so some day, when memory hotplug is supported, it should
just work out of the box when all of a sudden a second channel appears.

The Sandy Bridge EDAC driver uses a register in the IMC_DDRIO CSR

But this device does not exist on some single socket Sandy Bridge
servers. While the type of DIMMs is nice to know, it is not essential

Pull EDAC fixes and ghes-edac from Mauro Carvalho Chehab:
"For:

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

With the current version of CPER, there's no way to associate an
error with the memory error. So, the error location in EDAC
layers is unused.
As CPER has its own idea about memory architectural layers, just
output whatever is there inside the driver's detail at the RAS
tracepoint.
The EDAC location keeps untouched, in the case that, in some future,
we could actually map the error into the dimm labels.

APEI GHES and i7core_edac/sb_edac currently can be loaded at
the same time, but those are Highlander modules:
"There can be only one".
There are two reasons for that:
1) Each driver assumes that it is the only one registering at
the EDAC core, as it is driver's responsibility to number
the memory controllers, and all of them start from 0;
2) If BIOS is handling the memory errors, the OS can't also be
doing it, as one will mangle with the other.
So, we need to add an module owner's lock at the EDAC core,
in order to avoid having two different modules handling memory
errors at the same time. The best way for doing this lock seems
to use the driver's name, as this is unique, and won't require
changes on every driver.

After running a series of tests on an HP DL320, filled with different
memory sizes, it was noticed that, when filled with just one DIMM
on such hardware, the driver wrongly detects twice the memory, and
thinks that both channels 0 and 1 are filled.
It seems to be partially caused by the BIOS and partially by the driver.
The i3200_edac current logic would be working fine if the BIOS were
disabling the unused second channel when just one DIMM is connected,
in order to do power-saving, as recommended on this chipset's datasheet.
However, the BIOS on this particular machine doesn't do it:
[ 16.741421] EDAC DEBUG: how_many_channels: In dual channel mode
[ 16.741424] EDAC DEBUG: how_many_channels: 2 DIMMS per channel enabled
So, the driver were assuming that 2 channels are enabled (well, they are,
but the second is unused).
Combined with that, I found two issues at the logic that creates the
EDAC data, that were failing when the two channels are not equally
filled (AFAICT, that happens only when just 1 DIMM is plugged).
The first one is that a 0 at DRB means that nothing is filled. The
driver's logic, however, do some calculation with that.
The second one is that the logic that fills the DIMM data currently
assumes that both channels are equally filled.
I tested the system already with the current configuration and my
patch and it is now working fine. So, for a 2R single DIMM 2Gb memory
at dimm slot 01 (channel 0), it is now displaying:
[ 16.741406] EDAC DEBUG: i3200_get_drbs: drb[0][0] = 16, drb[1][0] = 0
[ 16.741410] EDAC DEBUG: i3200_get_drbs: drb[0][1] = 32, drb[1][1] = 0
[ 16.741413] EDAC DEBUG: i3200_get_drbs: drb[0][2] = 32, drb[1][2] = 0
[ 16.741416] EDAC DEBUG: i3200_get_drbs: drb[0][3] = 32, drb[1][3] = 0
...
[ 16.741896] EDAC DEBUG: i3200_probe1: csrow 0, channel 0, size = 1024 Mb
[ 16.741899] EDAC DEBUG: i3200_probe1: csrow 1, channel 0, size = 1024 Mb
and the corresponding sysfs nodes are now properly filled.

Pull x86 platform changes from Ingo Molnar:
- Support for the Technologic Systems TS-5500 platform, by Vivien
Didelot
- Improved NUMA support on AMD systems:
Add support for federated systems where multiple memory controllers
can exist and see each other over multiple PCI domains. This
basically means that AMD node ids can be more than 8 now and the code
handling this is taught to incorporate PCI domain into those IDs.
- Support for the Goldfish virtual Android emulator, by Jun Nakajima,
Intel, Google, et al.
- Misc fixlets.
