I just saw that this did not land yet on master.
I also noticed that this patch is not in
https://github.com/alistair23/qemu/tree/riscv-to-apply.next or
https://github.com/alistair23/qemu/commits/riscv-to-apply.for-upstream.
Was there some issue with the patch?
Meanwhile a lot of additional extensions got defined in the hwprobe
interface (patches are already merged in the kernel).
I'll send out a patch for these in a few minutes and include this
patch here as well.
