Should something more generic like the x86 alternative code be done for ARM? It's very likely we will need patching in other places like for UP and SMP in one kernel.
I think yes, we need to - I can't see how we can sensibly combine kernels without this. However, the effect of this is that XIP can't use this - as the kernel text is read-only.
