Given that all ARMv8 CPUs can support SW_PAN, it is more likely to be
enabled than the ARMv8.1 PAN. I'd vote for supporting the workaround in
that case too, and hope that people do enable the HW version.

Okay, I'll do my best to add support for the SW PAN case. I rebased and
submitted v6 of the E1009 patch [1] so that it no longer depends on this
patch landing first, if you all are inclined to pick it up while work on
this E1003 patch continues.

The alternative is not enabling SW_PAN (at runtime) if this errata is
present, along with a warning stating that hardware-PAN should be
enabled in kconfig instead. Not sure what distributions will make of that
though.

Yup, I queued that one locally and I'll push to -next tomorrow.

Thanks,
