.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.

As reported by Vernon Mauery <vernux@us.ibm.com>, X5670 (Westmere-EP) uses a
different register for one of the uncore PCI devices. Add support for
it.
Those are the PCI ID's on this new chipset:
fe:00.0 0600: 8086:2c70 (rev 02)
fe:00.1 0600: 8086:2d81 (rev 02)
fe:02.0 0600: 8086:2d90 (rev 02)
fe:02.1 0600: 8086:2d91 (rev 02)
fe:02.2 0600: 8086:2d92 (rev 02)
fe:02.3 0600: 8086:2d93 (rev 02)
fe:02.4 0600: 8086:2d94 (rev 02)
fe:02.5 0600: 8086:2d95 (rev 02)
fe:03.0 0600: 8086:2d98 (rev 02)
fe:03.1 0600: 8086:2d99 (rev 02)
fe:03.2 0600: 8086:2d9a (rev 02)
fe:03.4 0600: 8086:2d9c (rev 02)
fe:04.0 0600: 8086:2da0 (rev 02)
fe:04.1 0600: 8086:2da1 (rev 02)
fe:04.2 0600: 8086:2da2 (rev 02)
fe:04.3 0600: 8086:2da3 (rev 02)
fe:05.0 0600: 8086:2da8 (rev 02)
fe:05.1 0600: 8086:2da9 (rev 02)
fe:05.2 0600: 8086:2daa (rev 02)
fe:05.3 0600: 8086:2dab (rev 02)
fe:06.0 0600: 8086:2db0 (rev 02)
fe:06.1 0600: 8086:2db1 (rev 02)
fe:06.2 0600: 8086:2db2 (rev 02)
fe:06.3 0600: 8086:2db3 (rev 02)
(as usual, the same PCI devices repeat at ff: bus)
The PCI device 8086:2c70 is shown as:
fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic
Non-core Registers (rev 02)
So, for this device to be recognized, it is only a matter of adding this
new PCI ID to the driver.

This fixes an error in function i7core_check_error
In commit ca9c90ba09ca3c9799319f46a56f397afbf617c2 which converts the
driver to use double buffering, there is a change in the logic. Before,
if mce_count was zero, it skipped over a couple of statements and
finished out with a call to the *check_mc_ecc_err function. The current
code checks to see if mce_count is 0 and then exits.
This change reverts the behavior back to the original where if there are
no errors to report, we skip to the end and call the *check_mc_ecc_err
function.
This fix allows the driver to work again on my Nehalem based blades
again.

Instead of displaying 3 values at the same var, break it into 3
different sysfs nodes:
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2
For registered dimms, however, the error counters are already being
displayed at:
/sys/devices/system/edac/mc/mc0/csrow*/ce_count
So, there's no need to add any extra sysfs nodes.

The old remove module stragegy didn't work on devices with multiple
cores, since only one PCI device is used to open all mc's, due to
Nehalem nature.
Also, it were based at pdev value. However, this doesn't point to the
pci device used at mci->dev.
So, instead, it unregisters all devices at once, deleting them from the
device list.

Instead of using a static table assuming always 2 CPU sockets, allocate
space dynamically for Nehalem PCI devs.
This patch is part of a series of patches that changes i7core_edac to
allow more than 2 sockets and to properly report one memory controller
per socket.

Just cosmetics. instead of showing something like:
socket 0, channel 2dimm0: 1
dimm1: 0
dimm2: 0
socket 1, channel 2dimm0: 0
dimm1: 0
dimm2: 0
Show:
socket 0, channel 2 RDIMM0: 1 RDIMM1: 0 RDIMM2: 0
socket 0, channel 2 RDIMM0: 0 RDIMM1: 0 RDIMM2: 0
This is more synthetic and easier to parse.

On the Xeon 55XX series cpus the pci deives are not exposed via acpi so
we much explicitly probe them to make the usable as a Linux PCI device.
This moves the detection of this state to before pci_register_driver is
called. Its present position was not working on my systems, the driver
would complain about not finding a specific device.
This patch allows the driver to load on my systems.

Instead of assuming that the entire machine has either registered or
unregistered memories, do it at CPU socket based.
While here, fix a bug at i7core_mce_output_error(), where the we're
using m->cpu directly as if it would represent a socket. Instead, the
proper socket_id is given by cpu_data[m->cpu].phys_proc_id.

Nehalem and upper chipsets provide an special device that has corrected memory
error counters detected with registered dimms. This device is only seen if
there are registered memories plugged.
After this patch, on a machine fully equiped with RDIMM's, it will use the
Device 3 function 2 to count corrected errors instead on relying at mcelog.
For unregistered DIMMs, it will keep the old behavior, counting errors
via mcelog.
This patch were developed together with Keith Mannthey <kmannth@us.ibm.com>

There were two stupid error injection bugs introduced by wrong
cut-and-paste: one at socket store, and another at the error inject
register. The last one were causing the code to not work at all.
While here, adds debug messages to allow seeing what registers are being
set while sending error injection.
