Where do I find all the available options/devices I can use in my kernel config

[Dany]

Reading some forums, I discovered I could use the following options in 
my kernel configuration (5.2):
options CPU_ATHLON_SSE_HACK
options CPU_ENABLE_SSE

I looked at the GENERIC kernel config but there were no mention of those 
2 options. Where can I find an exhaustive list of available 
options/devices I can use in my custom kernel config file?

Thank you
Dany
