Can this ^^^ be also removed now that rte_vhost_va_from_guest_pa() is
promoted to non-experimental? It is marked as deprecated in API (see
below) but i don't see anything in the deprecation documentation.

commit 9553e6e408883b3677e208dc66049bcd7f758529
Author: Maxime Coquelin <maxime.coquelin@redhat.com>
Date:   Wed Mar 14 17:31:25 2018 +0100

    vhost: deprecate unsafe GPA translation API

    This patch marks rte_vhost_gpa_to_vva() as deprecated because
    it is unsafe. Application relying on this API should move
    to the new rte_vhost_va_from_guest_pa() API, and check
    returned length to avoid out-of-bound accesses.

    This issue has been assigned CVE-2018-1059.

Good point. I think it can be removed now. But we didn't send the deprecation
notice last release. I am not sure if it's ok to remove it this release.

@Ray & Maxime,

What do you think? I think since this API is unsafe and the safe version is
promoted, it makes sense to remove this.

Thanks,
Chenbo

Strictly speaking there should have been depreciation notice. 
However if the API has been marked depreciated since 2018 and _is_ unsafe.
You'd have to imagine that is sufficient to warrant removal at this stage. 

Thomas, David and Ferruh - any inputs/comments or objections?

I aagree it can be removed in this release. SPDK project was the only
user I'm aware of, and they migrated to the safe variant long time ago.

I propose to apply this patch first, then I will post a patch removing
this deprecated symbol if nobody disagree.
