Taking my feedback on the other patch this is now named finalize_vcpu()

...instead of 'capability' this is 'extension' and...

No need to wrap these lines. It looks better to go long. And the output of
print_reg() doesn't wrap and this should just be a copy+paste of that. But
I see print_reg() output wasn't used to generate these lists since...

...all the above would just be indices rather than named registers. I
guess that's better for these registers.

I think all the above should have the size KVM_REG_SIZE_ULONG. Please also
test with a 32-bit host.

I wouldn't wrap these either.

Also most of these should be KVM_REG_SIZE_ULONG.

What about configs which include the zicbo* block size registers, AIA
register configs, and the ISA and SBI registers?
