This is a bit too much feature patches IMO, it's a complete
architecture port. I agree it's a backport from upstream, so it's not
too bad. But since glibc 2.27, which includes this, is expected to be
released on February 1st, I prefer to post-pone this change until glibc
2.27 gets released and we move to it.
