Actually this is already in.
While "Planning/2.2" says "all features should have patches posted on
the mailing list", the actual page describing soft feature freeze is
more lenient:
By the date of the soft feature freeze, any non-trivial feature
should have some code posted to the qemu-devel mailing list if it's
targeting a given release. Major features, and in particular
features with a high likelihood of breaking things, should already
be in the process of being merged.
This patch was fairly trivial, as it only adds a few memcpys and a
subsection. Likelihood of breaking things is basically zero because
AVX512 does not yet exist in silicon. Eduardo reviewed the patch
promptly and agreed with putting it in 2.2, so that's what I did.
