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

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.

The edac core will warrant that just one driver will be used,

For now, the EDAC driver does nothing but to register at the

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.

Create a debugfs direcotry i5100_edac/mcX for each memory controller and
add nodes to control how fault injection is preformed.
After configuring an injection using inject_channel, inject_deviceptr1,
inject_deviceptr2, inject_eccmask1, inject_eccmask2 and inject_hlinesel
trigger the injection by writing anything to inject_enable.
Example of a CE injection:
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel
echo 61440 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable
Example of UE injection:
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel
echo 2 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel
echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1
echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask2
echo 17 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr1
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr2
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable
Sometimes it is needed to enable the injection more then once (echo to
the inject_enable node) for the injection to happen, I am not sure why.

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.

Currently, it is not possible to know, when debug is enabled,
if the driver is using 2 DIMMS per channel mode or not. It is
not possible to know the values of the drbs registers, used
to identify the memory rank sizes.
Add debug for both, as it helps to track issues on the driver.

Merge tag 'edac_fixes_for_3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp
Pull EDAC fixes from Borislav Petkov:
"Two error path fixes causing a crash and a Kconfig fix for an issue
which spilled all EDAC suboptions into the 'Device Drivers' menu."
* tag 'edac_fixes_for_3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp:
EDAC: Cleanup device deregistering path
EDAC: Fix EDAC Kconfig menu
EDAC: Fix kernel panic on module unloading
Use device_unregister to replace put_device + device_del for
cleanup, and fix the potential use after free.

After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering
the "Device Drivers" toplevel menu in menuconfig, the suboptions behind
EDAC appeared merged with the rest of the device drivers types. This was
because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig
bool which was defined after the menu definition.
When pushing EDAC_SUPPORT up, before the menu definition, the variable
is defined earlier and the above menuconfig artifact doesn't happen.
Drop a useless menuconfig comment while at it.

This patch fixes use-after-free and double-free bugs in
edac_mc_sysfs_exit(). mci_pdev has single reference and put_device()
calls mc_attr_release() which calls kfree(). The following
device_del() works with already released memory. An another kfree() in
edac_mc_sysfs_exit() releses the same memory again. Great.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Pull MIPS updates from Ralf Baechle:
"The MIPS bits for 3.8. This also includes a bunch fixes that were
sitting in the linux-mips.org git tree for a long time. This pull
request contains updates to several OCTEON drivers and the board
support code for BCM47XX, BCM63XX, XLP, XLR, XLS, lantiq, Loongson1B,
updates to the SSB bus support, MIPS kexec code and adds support for
kdump.
When pulling this, there are two expected merge conflicts in
include/linux/bcma/bcma_driver_chipcommon.h which are trivial to
resolve, just remove the conflict markers and keep both alternatives."
