Merge branch 'x86-ras-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 RAS changes from Ingo Molnar: "[ The reason for drivers/ updates is that Boris asked for the drivers/edac/ changes to go via x86/ras in this cycle ] Main changes: - AMD CPUs: . Add ECC event decoding support for new F15h models . Various erratum fixes . Fix single-channel on dual-channel-controllers bug. - Intel CPUs: . UC uncorrectable memory error parsing fix . Add support for CMC (Corrected Machine Check) 'FF' (Firmware First) flag in the APEI HEST - Various cleanups and fixes" * 'x86-ras-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: amd64_edac: Fix incorrect wraparounds amd64_edac: Correct erratum 505 range cpc925_edac: Use proper array termination x86/mce, acpi/apei: Only disable banks listed in HEST if mce is configured amd64_edac: Get rid of boot_cpu_data accesses amd64_edac: Add ECC decoding support for newer F15h models x86, amd_nb: Clarify F15h, model 30h GART and L3 support pci_ids: Add PCI device ID functions 3 and 4 for newer F15h models. x38_edac: Make a local function static i3200_edac: Make a local function static x86/mce: Pay no attention to 'F' bit in MCACOD when parsing 'UC' errors APEI/ERST: Fix error message formatting amd64_edac: Fix single-channel setups EDAC: Replace strict_strtol() with kstrtol() mce: acpi/apei: Soft-offline a page on firmware GHES notification mce: acpi/apei: Add a boot option to disable ff mode for corrected errors mce: acpi/apei: Honour Firmware First for MCA banks listed in APEI HEST CMC
