Merge branch 'x86-mce-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 RAS changes from Ingo Molnar: "The biggest change adds support for Intel 'CPER' (UEFI Common Platform Error Record) error logging, which builds upon an enhanced error logging mechanism available on Xeon processors. Full description is here: http://www.intel.com/content/www/us/en/architecture-and-technology/enhanced-mca-logging-xeon-paper.html This change provides a module (and support code) to check for an extended error log and prints extra details about the error on the console" * 'x86-mce-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: ACPI, x86: Fix extended error log driver to depend on CONFIG_X86_LOCAL_APIC dmi: Avoid unaligned memory access in save_mem_devices() Move cper.c from drivers/acpi/apei to drivers/firmware/efi EDAC, GHES: Update ghes error record info ACPI, APEI, CPER: Cleanup CPER memory error output format ACPI, APEI, CPER: Enhance memory reporting capability ACPI, APEI, CPER: Add UEFI 2.4 support for memory error DMI: Parse memory device (type 17) in SMBIOS ACPI, x86: Extended error log driver for x86 platform bitops: Introduce a more generic BITMASK macro ACPI, CPER: Update cper info ACPI, APEI, CPER: Fix status check during error printing
