How do we manage the stable series wrt this issue?
qemu-kvm-0.12.5 has a regression within the stable series that this
patch fixes. qemu 0.12.5 does not, but only because it does not emulate
polarity in the I/O APIC correctly.
There are several paths we could take:
- do nothing, bug is fixed in mainline
- release a seabios 0.x.1 for qemu 0.13.1 with this patch
- same, plus seabios 0.y.1 for qemu 0.12.6 with this patch
- skip qemu (which is not truly affected), patch qemu-kvm's copy of
seabios for both 0.12.z and 0.13.z
The third option is the most "correct" from a release engineering point
of view, but involves more work for everyone. The fourth is quick pain
relief but is a little forky.

I'm okay with making tags and branches of seabios for bug fixes. So
far qemu/kvm has just grabbed various builds of seabios - is it
worthwhile to branch off of the seabios-0.6.1 version - which would
mean qemu/kvm would pull in additional changes beyond the bug fix
above?

qemu 0.12 is based on 0.5.1-stable, appears to be an untagged commit
qemu 0.13 is based on 17d3e46511, doesn't appear to be a part of a
branch or a tag?
git-wise, tags are more important than branches. You can always
retrofit a branch to a tag (and you can always retrofit a tag to a
commit hash). For the qemu git repositories, neither matter so much
since the commit is recorded in git; but the distro people really like
nice stable tags with lots of digits and dots in them.

On the last kvm conf call Anthony said that he'll be happy to include an
updated seabios with qemu 0.13.1, so a new release would be appreciated.

I branched and tagged "rel-0.6.1.1". It only has 6d5a2172
cherry-picked into it.
