Merge tag 'x86_cpu_for_v6.4_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull x86 cpu model updates from Borislav Petkov:

 - 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
