The original code before Phoebe's patch almost gets that right, but is a

It looks like the overwhelming majority of platforms *do* use the
standard ldrex/strex loops, so I think we should be changing the
default: let any platform with a weird kernel opt itself out of inline
atomics.
Sounds reasonable to me :)
Cheers.
