Due to bug 1522678, we will not be able to enable

Is there an upstream bug report/thread for this? It would be useful to
at least make the appropriate ARM maintainers aware of the problem so
if they're interested enough or see value in it they can deal with it
and then it can be enabled later.
Nobody has written a patch, so 32-bit ARM uses the generic bits, which
are suboptimal (in terms of ABI compliance and protection level) and, it
appears, not really usable.
Even the final aarch64 bits are still pending review by the ARM
maintainers.
The aarch64 bits still have not been committed. It might help if you
pinged your Arm contacts again.
Thanks,
Florian
