x86/cpu: Add Xeon Emerald Rapids to list of CPUs that support PPIN (2023-04-05 20:01:52 +0200)
---------------------------------------------------------------- - Add Emerald Rapids to the list of Intel models supporting PPIN
- Finally use a CPUID bit for split lock detection instead of enumerating every model
- Make sure automatic IBRS is set on AMD, even though the AP bringup code does that now by replicating the MSR which contains the switch
---------------------------------------------------------------- Borislav Petkov (AMD) (1): x86/CPU/AMD: Make sure EFER[AIBRSE] is set
Fenghua Yu (1): x86/split_lock: Enumerate architectural split lock disable bit
Tony Luck (1): x86/cpu: Add Xeon Emerald Rapids to list of CPUs that support PPIN
