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
