76a7bd8113 i7core_edac: return -ENODEV when devices were already probed
Due to the nature of i7core, we need to probe and attach all PCI
devices used by this driver during the first time probe is called.
However, PCI core will call the probe routine one time for each CPU
socket. If we return -EINVAL to those calls, it would seem that the
driver fails, when, in fact, there's no more devices left to initialize.

Changing the return code to -ENODEV solves this issue.

3c52cc57cc i7core_edac: properly terminate pci_dev_table
At pci_xeon_fixup(), it waits for a null-terminated table, while at
i7core_get_all_devices, it just do a for 0..ARRAY_SIZE. As other tables
are zero-terminated, change it to be terminate with 0 as well, and fixes
a bug where it may be running out of the table elements.

a3e1541637 i7core_edac: Avoid PCI refcount to reach zero on successive load/reload
That's a nasty bug that took me a lot of time to track, and whose
solution took just one line to solve. The best fragrances and the worse
poisons are shipped on the smalest bottles.

The drivers/pci/quick.c implements the pci_get_device function. The normal
behavior is that you call it, the function returns you a pdev pointer
and increment pdev->kobj.kref.refcount of the pci device. However,
if you want to keep searching an object, you need to pass the previous
pdev function to the search.

When you use a not null pointer to pdev "from" field, pci_get_device
will decrement pdev->kobj.kref.refcount, assuming that the driver won't
be using the previous pdev.

The solution is simple: we just need to call pci_dev_get() manually,
for the pdev's that the driver will actually use.

79daef2099 i7core_edac: Fix refcount error at PCI devices
Probably due to a bug or some testing logic at PCI level, device
refcount for <bus>:00.0 device is decremented at the end of the
pci_get_device, made by i7core_get_all_devices(). The fact is that
the first versions of the driver relied on those devices to probe
for Nehalem, but the current versions don't use it at all.

So, let's just remove those devices from the driver, making it simpler
and fixing the bug.

accf74fff3 i7core_edac: don't use a freed mci struct
This is a nasty bug. Since kobject count will be reduced by zero by
edac_mc_del_mc(), and this triggers the kobj release method, the
mci memory will be freed automatically. So, all we have left is ctl_name,
as shown by enabling debug:

[   80.822186] EDAC DEBUG: in drivers/edac/edac_mc_sysfs.c, line at 1020: edac_remove_sysfs_mci_device()  remove_link

[   80.843776] EDAC DEBUG: in drivers/edac/edac_mc_sysfs.c, line at 640: edac_mci_control_release() mci instance idx=0 releasing

[   80.862936] EDAC DEBUG: in drivers/edac/i7core_edac.c, line at 2089: (null): free structs

[   80.888043] EDAC DEBUG: in drivers/edac/i7core_edac.c, line at 1232: drivers/edac/i7core_edac.c: i7core_put_devices()

Also, kfree(mci) shouldn't happen at the kobj.release, as it happens
when edac_remove_sysfs_mci_device() is called, but the logic is:
	edac_remove_sysfs_mci_device(mci);
	edac_printk(KERN_INFO, EDAC_MC,
		"Removed device %d for %s %s: DEV %s\n", mci->mc_idx,
		mci->mod_name, mci->ctl_name, edac_dev_name(mci));
So, as the edac_printk() needs the mci struct, this generates an OOPS.

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.
