Re: [PATCH v6 00/13] s390x/tcg: Implement Vector-Enhancements Facility 2

[David Miller]

Sorry,  It was in the discussion for v4 patches,  as an attachment .
mail thread:
[PATCH v4 10/11] tests/tcg/s390x: Tests for Vector Enhancements Facility 2
So it likely never made it to the mailing list.

I've reattached and will forward the patch (by itself) to the mailing list.

I think the other solution works just as well by ignoring if compiler
doesn't support z15.

I just thought I'd bring it back up as I saw discussion about it.

Thanks
- David Miller
