x86 implements all of them by default - and we just

ARM 64 only has alternative while ARM 32 has none of them.

And while at it change the livepatch common code that
would benefit from this.

Surely livepatch should select alternatives ?

Do you mean for ARM? If so, alternatives is not supported by ARM32 so it should not be selected.

Cheers,
