Hi Hans!

Thank you for your Acked-by! The cpuid patch has been merged in to 
v6.0-rc3. I am not sure why its complaining about 
INTEL_FAM6_RAPTORLAKE_S being undeclared.

patch - ea902bcc1943f7539200ec464de3f54335588774 : "x86/cpu: Add new 
Raptor Lake CPU model number".

I made sure its built without errors before sending it out.
