My take on that would be that we would want to wait for
kernel work to hit mainline before taking the corresponding
QEMU changes. (In particular there's always the possibility
of ABI changes like syscall numbering or struct layout
being required as part of the kernel patch review process.
We made this mistake before in letting the unicore support
get in when it wasn't the upstream kernel ABI.)
