What it is pointed by a csrow/channel vector is a rank information, and
not a channel information.
On a traditional architecture, the memory controller directly access the
memory ranks, via chip select rows. Different ranks at the same DIMM is
selected via different chip select rows. So, typically, one
csrow/channel pair means one different DIMM.
On FB-DIMMs, there's a microcontroller chip at the DIMM, called Advanced
Memory Buffer (AMB) that serves as the interface between the memory
controller and the memory chips.
The AMB selection is via the DIMM slot, and not via a csrow.
It is up to the AMB to talk with the csrows of the DRAM chips.
So, the FB-DIMM memory controllers see the DIMM slot, and not the DIMM
rank. RAMBUS is similar.
Newer memory controllers, like the ones found on Intel Sandy Bridge and
Nehalem, even working with normal DDR3 DIMM's, don't use the usual
channel A/channel B interleaving schema to provide 128 bits data access.
Instead, they have more channels (3 or 4 channels), and they can use
several interleaving schemas. Such memory controllers see the DIMMs
directly on their registers, instead of the ranks, which is better for
the driver, as its main usageis to point to a broken DIMM stick (the
Field Repleceable Unit), and not to point to a broken DRAM chip.
The drivers that support such such newer memory architecture models
currently need to fake information and to abuse on EDAC structures, as
the subsystem was conceived with the idea that the csrow would always be
visible by the CPU.
To make things a little worse, those drivers don't currently fake
csrows/channels on a consistent way, as the concepts there don't apply
to the memory controllers they're talking with. So, each driver author
interpreted the concepts using a different logic.
In order to fix it, let's rename the data structure that points into a
DIMM rank to "rank_info", in order to be clearer about what's stored
there.
Latter patches will provide a better way to represent the memory
hierarchy for the other types of memory controller.

When i5400_edac driver is removed and re-loaded a few times, it causes
an OOPS, as it is currently decrementing some PCI device usage two
times.
When called inside a loop, pci_get_device() will call
pci_put_device(). That mangles the error count. In this specific
case, it seems easier to just duplicate the call.
Also fixes the error logic when pci_get_device fails.

If I only ack the detection register after a error have been detected
I'm unable to reliably detect errors. I have verified this behavior
using both an error injection DIMM and software to inject errors.
I can't find any documentation supporting this behavior in Intel 5100
Memory Controller Hub Chipset, see 1. So this is all based on
experimentation.

We can identify dram interleave mode from the Dram Rule register
rather than Dram Interleave list register.
In this context, the reg of INTERLEAVE_MODE(reg) contains the Dram
Interleave list register, we can't get interleave mode from the reg,
while the variable interleave_mode saves the the mode got from the
Dram Rule register, so we use the variable to replace
INTERLEAVE_MDDE(reg) here.

gpio-regulator driver) and Axel Lin continued his relentless and

This branch takes the PowerPC irq_host infrastructure (reverse mapping
from Linux IRQ numbers to hardware irq numbering), generalizes it,
renames it to irq_domain, and makes it available to all architectures.
Originally the plan has been to create an all-new irq_domain
implementation which addresses some of the powerpc shortcomings such
as not handling 1:1 mappings well, but doing that proved to be far
more difficult and invasive than generalizing the working code and
refactoring it in-place. So, this branch rips out the 'new'
irq_domain and replaces it with the modified powerpc version (in a
fully bisectable way of course). It converts all users over to the
new API and makes irq_domain selectable on any architecture.
No architecture is forced to enable irq_domain, but the infrastructure
is required for doing OpenFirmware style irq translations. It will
even work on SPARC even though SPARC has it's own mechanism for
translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x
are converted too.
The resulting irq_domain code is probably still too verbose and can be
optimized more, but that can be done incrementally and is a task for
follow-on patches.

This patch fixes an issue when cifs_mount receives a
STATUS_BAD_NETWORK_NAME error during cifs_get_tcon but is able to
continue after an DFS ROOT referral. In this case, the return code
variable is not reset prior to trying to mount from the system referred
to. Thus, is_path_accessible is not executed and the final DFS referral
is not performed causing a mount error.
Use case: In DNS, example.com resolves to the secondary AD server
ad2.example.com Our primary domain controller is ad1.example.com and has
a DFS redirection set up from \\ad1\share\Users to \\files\share\Users.
Mounting \\example.com\share\Users fails.

The option REBOOT_ON_SUCCESS is global, and will have the machine reboot
the the box if all tests are successful. But a test may not want the
machine to reboot, and perhaps have the kernel it loaded be used to
install the next kernel. Or the last test may set up a kernel that the
user may want to look at. In this case, the user could have the global
option REBOOT_ON_SUCCESS be true, but if a test is defined to run at the
end, that test can override the global option and keep the kernel it
installed for the user to log in with.

The pnfs-objects protocol mandates that we autologin into devices not
present in the system, according to information specified in the
get_device_info returned from the server.
The Protocol specifies two login hints.
1. An IP address:port combination
2. A string URI which is constructed as a URL with a protocol prefix
followed by :// and a string as address. For each protocol prefix
the string-address format might be different.
We only support the second option. The first option is just redundant
to the second one.
NOTE: The Kernel part of autologin does not parse the URI string. It
just channels it to a user-mode script. So any new login protocols should
only update the user-mode script which is a part of the nfs-utils package,
but the Kernel need not change.
We implement the autologin by using the call_usermodehelper() API.
(Thanks to Steve Dickson <steved@redhat.com> for pointing it out)
So there is no running daemon needed, and/or special setup.
We Add the osd_login_prog Kernel module parameters which defaults to:
/sbin/osd_login
Kernel try's to upcall the program specified in osd_login_prog. If the file is
not found or the execution fails Kernel will disable any farther upcalls, by
zeroing out osd_login_prog, Until Admin re-enables it by setting the
osd_login_prog parameter to a proper program.
Also add text about the osd_login program command line API to:
Documentation/filesystems/nfs/pnfs.txt
and documentation of the new osd_login_prog module parameter to:

We do the dss driver registration in a rather strange way: we have the
higher level omapdss driver, and we use that driver's probe function to
register the drivers for the rest of the dss devices.
There doesn't seem to be any reason for that, and additionally the
soon-to-be-merged patch "ARM: OMAP: omap_device: remove
omap_device_parent" will break omapdss initialization with the current
registration model.
This patch changes the registration for all drivers to happen at the
