Intel client EDAC drivers duplicate address translation logic and rely on platform-specific IMC counts even though the IMCs can be detected at runtime. This series fixes several decoding bugs, replaces static IMC counts with runtime detection, and consolidates the common translation logic to simplify future maintenance. Patches 1-5: Fix several correctness issues in the ie31200 and igen6 drivers, including interleave boundary handling, channel hash selection, non-hash address decoding, and logged error address translation. Patches 6-7: Do small cleanups. Patches 8-9: Detect the number of IMCs at runtime, allowing new SoCs to be supported without maintaining per-platform IMC counts while eliminating redundant resource configuration tables. Patch 10: Refactor the address translation logic by introducing shared helpers for the common interleave and hash translation operations. This removes duplicated implementations across multiple decoding paths, making future changes easier while preserving existing behavior.
