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: - SCI reporting for other error types not only correctable ones - GHES cleanups - Add the functionality to override error reporting agents as some machines are sporting a new extended error logging capability which, if done properly in the BIOS, makes a corresponding EDAC module redundant - PCIe AER tracepoint severity levels fix - Error path correction for the mce device init - MCE timer fix - Add more flexibility to the error injection (EINJ) debugfs interface * 'x86-ras-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, mce: Fix mce_start_timer semantics ACPI, APEI, GHES: Cleanup ghes memory error handling ACPI, APEI: Cleanup alignment-aware accesses ACPI, APEI, GHES: Do not report only correctable errors with SCI ACPI, APEI, EINJ: Changes to the ACPI/APEI/EINJ debugfs interface ACPI, eMCA: Combine eMCA/EDAC event reporting priority EDAC, sb_edac: Modify H/W event reporting policy EDAC: Add an edac_report parameter to EDAC PCI, AER: Fix severity usage in aer trace event x86, mce: Call put_device on device_register failure
