Hi,
work on 4.9.77 is mostly done, so yes I'd like to push it to stretch before
next point relase. 4.9.78 is just out but I'm unsure if we want to hold it or
not.

That beeing said, retpoline support in the kernel is not enough. It also needs
gcc fixes, which are not yet available, as far as I can tell. So while we can
push an updated kernel to stretch, spectre won't be mitigated.
