On balance, I think it's appropriate to make the change.  I think

maintainers to do this.

Thanks for the carefully considered reply.


A problem with "x86 stakeholders" is that we've historically been
rather poor at finding our users and consulting them before making
changes.  This has resulted in a number of flamewars, particularly
over type-based alias analysis.


It may even be possible to preemptively generate a flamewar with a post to something like the LKML laying out the pros and cons.


It is a change to the de facto ABI. Think back to what happened with the x86 direction flag issue.
