Merge tag 'edac_updates_for_v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras
Pull EDAC updates from Borislav Petkov: "The usual EDAC stuff which managed to trickle in for 5.15: - Add new HBM2 (High Bandwidth Memory Gen 2) type and add support for it to the Intel SKx drivers - Print additional useful per-channel error information on i10nm, like on SKL - Don't load the AMD EDAC decoder in virtual images - The usual round of fixes and cleanups" * tag 'edac_updates_for_v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras: EDAC/i10nm: Retrieve and print retry_rd_err_log registers EDAC/i10nm: Fix NVDIMM detection EDAC/skx_common: Set the memory type correctly for HBM memory EDAC/altera: Skip defining unused structures for specific configs EDAC/mce_amd: Do not load edac_mce_amd module on guests EDAC/mc: Add new HBM2 memory type EDAC/amd64: Use DEVICE_ATTR helper macros
