Merge tag 'edac_updates_for_v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras
Pull EDAC updates from Borislav Petkov: - The AMD memory controllers data fabric version 4.5 supports non-power-of-2 denormalization in the sense that certain bits of the system physical address cannot be reconstructed from the normalized address reported by the RAS hardware. Add support for handling such addresses - Switch the EDAC drivers to the new Intel CPU model defines - The usual fixes and cleanups all over the place * tag 'edac_updates_for_v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras: EDAC: Add missing MODULE_DESCRIPTION() macros EDAC/dmc520: Use devm_platform_ioremap_resource() EDAC/igen6: Add Intel Arrow Lake-U/H SoCs support RAS/AMD/FMPM: Use atl internal.h for INVALID_SPA RAS/AMD/ATL: Implement DF 4.5 NP2 denormalization RAS/AMD/ATL: Validate address map when information is gathered RAS/AMD/ATL: Expand helpers for adding and removing base and hole RAS/AMD/ATL: Read DRAM hole base early RAS/AMD/ATL: Add amd_atl pr_fmt() prefix RAS/AMD/ATL: Add a missing module description EDAC, i10nm: make skx_common.o a separate module EDAC/skx: Switch to new Intel CPU model defines EDAC/sb_edac: Switch to new Intel CPU model defines EDAC, pnd2: Switch to new Intel CPU model defines EDAC/i10nm: Switch to new Intel CPU model defines EDAC/ghes: Add missing newline to pr_info() statement RAS/AMD/ATL: Add missing newline to pr_info() statement EDAC/thunderx: Remove unused struct error_syndrome
