x86 implements all of them by default - and we just
add two extra CONFIG_ variables to be declared in autoconf.h.

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.

Perhaps we need a "selects ALTERNATIVES if X86" then, but the x86 implementation of livepatching does strictly need alternatives support, and should be represented appropriately.
