Using the SLE12 branch directly may be tricky since there are different architecture targets for openSUSE and SLES. Unfortunately, those are details I can't get into just yet. I can share that we are not building 32-bit kernels for any architecture, so a SLE12 kernel used on openSUSE will have zero i586 testing performed on it as part of the SLE testing matrix. While I certainly wouldn't mind it happening, I don't know of any openSUSE plans to drop i586 support just yet.
Even if there were such plans, I have a feeling it is a bit late to do that in 13.1 :-)
I don't think Evergreen uses the SLES kernel, but it does use the same version as SLES and then it pulls in patches from the SLES kernel set of patches. I don't think it pulls all of them in, but that is a separate discussion.
From the technical point of view, I created a new branch from SLE11-SP2 at some point, merged the config files to match openSUSE-11.4 ones as closely as possible and did the ext4 related changes (ceph ones came later). Since then I keep merging SLE11-SP2 branch into evergreen-11.4 from time to time - usually once a week - or when a SLE11-SP2 update is submitted. Evergreen 11.4 kernel updates match SLE 11 SP2 updates. As
The Evergreen 11.4 kernel is based on SLE 11 SP2 kernel with only few code changes (IIRC I only removed the tricks making ext4 read-only and picked a bit more of the ceph backports as the way it is done in SLE11-SP2 breaks the build in parts which are disabled in SLE11-SP2 but enabled in openSUSE-11.4) but with different config(s) and some changes in the packaging. there are almost no code changes, the conflicts are only in config/ and, of course, kabi/ must be updated independently. For 13.1, IMHO the same approach based on SLE12 branch (i.e. SLE 12 GA) would be the best solution (or the least bad one). This time I want to start as soon as possible and provide the kernel as an alternative in OBS so that we can get more testing before 13.1 regular support finishes. But all this is still open to discussion - actually there has been no discussion about Evergreen 13.1 kernel yet (except this thread).
