As-per the patch acceptance policy, we cannot merge it now (just like KVM
patches) but we can always review and get the patches in final shape
by the time spec is frozen or ratified.

I think we should continue with the patch review and get this series in
good shape.

In fact, having this patches early on LKML is very helpful for people working
on RISC-V vector extension implementation in HW. On this line, this a good
contribution coming at the right time.
