2015-09-08sb_edac: correctly fetch DIMM width on Ivy Bridge and HaswellAristeu Rozanski
dimm_dev_type has been incorrectly determined in sb_edac. This patch fixes it for Ivy Bridge and Haswell only since nothing like exists for Sandy Bridge. We tested this patch in multiple systems matching the results with the installed memory modules.

2015-09-08sb_edac: look harder for DDRIO on Haswell systemsAristeu Rozanski
In case the memory banks are populated so the first channel isn't used, the DDRIO PCI device won't be visible and it won't be possible to determine the memory type.

2015-06-24EDAC, altera: Do not allow suspend when EDAC is enabledAlan Tull
Suspend-to-RAM and EDAC support are mutually exclusive on SOCFPGA. If EDAC is enabled, it will prevent the platform from going into suspend. The reason is that the IRQ vectors for OCRAM reside on DDR and in Suspend-to-RAM mode we're executing out of OCRAM. If an ECC error occurs, we can't handle it so it was decided to make them mutually exclusive.

2015-06-03sb_edac: Fix support for systems with two home agents per socketTony Luck
First noticed a problem on a 4 socket machine where EDAC only reported half the DIMMS. Tracked this down to the code that assumes that systems with two home agents only have two memory channels on each agent. This is true on 2 sockect ("-EP") machines. But four socket ("-EX") machines have four memory channels on each home agent. The old code would have had problems on two socket systems as it did a shuffling trick to make the internals of the code think that the channels from the first agent were '0' and '1', with the second agent providing '2' and '3'. But the code didn't uniformly convert from {ha,channel} tuples to this internal representation. New code always considers up to eight channels. On a machine with a single home agent these map easily to edac channels 0, 1, 2, 3. On machines with two home agents we map using: edac_channel = 4*ha# + channel So on a -EP machine where each home agent supports only two channels we'll fill in channels 0, 1, 4, 5, and on a -EX machine we use all of 0, 1, 2, 3, 4, 5, 6, 7.

But the non-a7mode path was incorrectly using GET_BITFIELD(addr, 7, 9) and so picking bits {9, 8, 7} thinko: BIT(1) of the dram_rule registers chooses whether to just use the {8, 7, 6} (or {8, 7, 9}) bits mentioned above as they are, or to XOR them with bits {18, 17, 16} but the code inverted the test.

2015-05-28EDAC: Cleanup atomic_scrub messBorislav Petkov
So first of all, this atomic_scrub() function's naming is bad. It looks like an atomic_t helper. Change it to edac_atomic_scrub(). The bigger problem is that this function is arch-specific and every new arch which doesn't necessarily need that functionality still needs to define it, otherwise EDAC doesn't compile. So instead of doing that and including arch-specific headers, have each arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c for ifdeffery. Much cleaner. And we already are doing this with another symbol - EDAC_SUPPORT. This is also much cleaner than having CONFIG_EDAC enumerate all the arches which need/have EDAC support and drivers. This way I can kill the useless edac.h header in tile too.

2015-05-20amd64_edac: enforce synchronous probeLuis R. Rodriguez
While testing asynchronous PCI probe on this driver I noticed it failed because the driver checks if any of the PCI devices have been bound to the driver after registering it, which obviously does not work if probing is asynchronous. While there are patches and discussions on how the driver should behave are ongoing, let's enforce synchronous probe for this driver for now.
