2020-10-26EDAC: Do not issue useless debug statements in the polling routineBorislav Petkov

2020-08-17EDAC: Replace HTTP links with HTTPS onesAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-08-10EDAC/ie31200: Fallback if host bridge device is already initializedJason Baron
The Intel uncore driver may claim some of the pci ids from ie31200 which means that the ie31200 edac driver will not initialize them as part of pci_register_driver(). Let's add a fallback for this case to 'pci_get_device()' to get a reference on the device such that it can still be configured. This is similar in approach to other edac drivers.

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
2019-11-09EDAC: Replace EDAC_DIMM_PTR() macro with edac_get_dimm() functionRobert Richter
The EDAC_DIMM_PTR() macro takes 3 arguments from struct mem_ctl_info. Clean up this interface to only pass the mci struct and replace this macro with a new function edac_get_dimm(). Also introduce an edac_get_dimm_by_index() function for later use. This allows it to get a DIMM pointer only by a given index. This can be useful if the DIMM's position within the layers of the memory controller or the exact size of the layers are unknown. Small style changes made for some hunks after applying the semantic patch.

2016-05-06EDAC, ie31200_edac: Add Skylake supportJason Baron
Skylake adjusts some register locations, but otherwise follows the existing model quite closely. I was able to verify that the 'ce_count' increments when 'bad dimms' are used. The accounting of 'ce_count' and 'ue_count' is the primary functionality of interest for us. Tested on Intel(R) Xeon(R) CPU E3-1260L v5 @ 2.90GHz.
