Merge tag 'ras-core-2020-06-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 RAS updates from Thomas Gleixner: "RAS updates from Borislav Petkov: - Unmap a whole guest page if an MCE is encountered in it to avoid follow-on MCEs leading to the guest crashing, by Tony Luck. This change collided with the entry changes and the merge resolution would have been rather unpleasant. To avoid that the entry branch was merged in before applying this. The resulting code did not change over the rebase. - AMD MCE error thresholding machinery cleanup and hotplug sanitization, by Thomas Gleixner. - Change the MCE notifiers to denote whether they have handled the error and not break the chain early by returning NOTIFY_STOP, thus giving the opportunity for the later handlers in the chain to see it. By Tony Luck. - Add AMD family 0x17, models 0x60-6f support, by Alexander Monakov. - Last but not least, the usual round of fixes and improvements" * tag 'ras-core-2020-06-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) x86/mce/dev-mcelog: Fix -Wstringop-truncation warning about strncpy() x86/{mce,mm}: Unmap the entire page if the whole page is affected and poisoned EDAC/amd64: Add AMD family 17h model 60h PCI IDs hwmon: (k10temp) Add AMD family 17h model 60h PCI match x86/amd_nb: Add AMD family 17h model 60h PCI IDs x86/mcelog: Add compat_ioctl for 32-bit mcelog support x86/mce: Drop bogus comment about mce.kflags x86/mce: Fixup exception only for the correct MCEs EDAC: Drop the EDAC report status checks x86/mce: Add mce=print_all option x86/mce: Change default MCE logger to check mce->kflags x86/mce: Fix all mce notifiers to update the mce->kflags bitmask x86/mce: Add a struct mce.kflags field x86/mce: Convert the CEC to use the MCE notifier x86/mce: Rename "first" function as "early" x86/mce/amd, edac: Remove report_gart_errors x86/mce/amd: Make threshold bank setting hotplug robust x86/mce/amd: Cleanup threshold device remove path x86/mce/amd: Straighten CPU hotplug path x86/mce/amd: Sanitize thresholding device creation hotplug path ...
