Fortify the interface to not accept negative values, remove
memctrl_int_store() as a result. Also, sanitize bandwidth setting by
making the argument a simple u32 instead of strange u32 pointer being
passed around for no obvious reason. Then, fix error handling and teach
it to return proper error values. Finally, make code more readable,
simplify debug messages.

MAINTAINERS: Add an entry for i7core_edac
i7core_edac: Avoid doing multiple probes for the same card
i7core_edac: Properly discover the first QPI device
As Nehalem/Nehalem-EP/Westmere devices uses several devices for the same
functionality (memory controller), the default way of proping devices doesn't
work. So, instead of a per-device probe, all devices should be probed at once.
This means that we should block any new attempt of probe, otherwise, it will
try to register the same device several times.

On Nehalem/Nehalem-EP/Westmere, the first QPI device is the last PCI bus.
The last bus is generally at 0x3f or 0xff, but there are also other systems
using different setups. For example, HP Z800 has 0x7f as the last bus.
This patch adds a logic to discover the last bus, dynamically detecting it
at runtime.

When calculating the DCT channel from the syndrome we need to know the
syndrome type (x4 vs x8). On F10h, this is read out from extended PCI
cfg space register F3x180 while on K8 we only support x4 syndromes and
don't have extended PCI config space anyway.
Make the code accessing F3x180 F10h only and fall back to x4 syndromes
on everything else.

.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.

This fixes an error in function i7core_check_error
In commit ca9c90ba09 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.

For registered dimms, however, the error counters are already being

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.
