I'm not entirely sure it's possible to fix even with
hand-rolled assembly, to be honest.

However there are a bunch of bugfixes in your tree
which it would be really nice to see upstreamed:
the sendmmsg patch, for instance. We can at least
get the aarch64 support to the same level as the
32 bit arm linux-user setup, which is genuinely
useful to people despite the well known races and
locking issues.
