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.

Hi Russell,

Sorry for late update on this. I've addressed your comments as below,
and really hope this can get into this merge window, so I'm also sending
this to your patch system right now ;-)

How does this affect the compiler's instruction scheduling w.r.t. previous
load instructions?
