2014-02-25i7300_edac: Fix device reference countJean Delvare
pci_get_device() decrements the reference count of "from" (last argument) so when we break off the loop successfully we have only one device reference - and we don't know which device we have. If we want a reference to each device, we must take them explicitly and let the pci_get_device() walk complete to avoid duplicate references. This is serious, as over-putting device references will cause the device to eventually disappear. Without this fix, the kernel crashes after a few insmod/rmmod cycles. Tested on an Intel S7000FC4UR system with a 7300 chipset.

2014-02-25i7core_edac: Fix PCI device reference countJean Delvare
The reference count changes done by pci_get_device can be a little misleading when the usage diverges from the most common scheme. The reference count of the device passed as the last parameter is always decreased, even if the function returns no new device. So if we are going to try alternative device IDs, we must manually increment the device reference count before each retry. If we don't, we end up decreasing the reference count, and after a few modprobe/rmmod cycles the PCI devices will vanish. In other words and as Alan put it: without this fix the EDAC code corrupts the PCI device list.

2014-02-24MCE, AMD: Fix decoding module loading on unsupported hwBorislav Petkov
We want to still be able to issue some error information on systems for which there is no decoding support (think older distro kernels here, for example). Therefore, we allow module registration but skip the per-family bank-specific decoders and issue the general information only, i.e.: [ 46.822828] [Hardware Error]: Error Status: Uncorrected, software containable error. [ 46.822846] [Hardware Error]: CPU:0 (15:30:0) MC0_STATUS[-|UE|-|-|-|-|-]: 0xa000000000010f0f [ 46.822858] [Hardware Error]: cache level: L3/GEN, mem/io: GEN, mem-tx: GEN, part-proc: GEN (timed out) with the hope that it still contains helpful useful bits.

Add pcie error interrupt edac support for mpc85xx, p3041, p4080, and p5020. The mpc85xx uses the legacy interrupt report mechanism - the error interrupts are reported directly to mpic. While the p3041/ p4080/p5020 attaches the most of error interrupts to interrupt zero. And report error interrupts to mpic via interrupt 0. This patch can handle both of them.
