Merge tag 'x86_urgent_for_v5.17_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov: - Add another Intel CPU model to the list of CPUs supporting the processor inventory unique number - Allow writing to MCE thresholding sysfs files again - a previous change had accidentally disabled it and no one noticed. Goes to show how much is this stuff used * tag 'x86_urgent_for_v5.17_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cpu: Add Xeon Icelake-D to list of CPUs that support PPIN x86/MCE/AMD: Allow thresholding interface updates after init
