For some reason, neither kernelci.org nor broonie's built bot include the stable/v4.1.y tree, but we do get reports for v4.1-rt, which unlike v4.4-rt show a number of warnings. Sasha, are you interested in backporting the fixes for these so we can eventually get a clean build and spot regressions more easily? A lot of these are just patches to shut up harmless warnings, but some also address real bugs.

Here, upstream commit fac8e0f57969 ("tunnels: Don't apply GRO to multiple layers of encapsulation.") seems to have been incorrectly backported into v4.1.y commit 066b300e5be4.
I have not analyzed why the function is now unused, but in the original patch it is used, unlike in the backport.

For some reason, neither kernelci.org nor broonie's built bot include the stable/v4.1.y tree, but we do get reports for v4.1-rt, which unlike v4.4-rt show a number of warnings. Sasha, are you interested in backporting the fixes for these so we can eventually get a clean build and spot regressions more easily? A lot of these are just patches to shut up harmless warnings, but some also address real bugs.
I can't speak for Sasha, but I'd certainly like to see the RT-specific build warnings fixed, and have already began the process of doing so.
The 4.1.y powerpc build is actually broken for newer gccs. The fix is upstream as 1e407ee3b21f9 ("powerpc/ptrace: Fix out of bounds array access warning"). There are other build warnings on other architectures as well. I've resent the patch last week to stable folks, but was having mailer problems, so perhaps need to resend.
I'm also happy to hear that the 4.1-rt is getting build testing by the build bot. Is there any way I can be CC'd on build reports on this branch? Or, is the best way for me just to subscribe to the list?

../net/ipv6/ip6_offload.c:261:25: warning: 'sit_gro_receive' defined but not used [-Wunused-function]Here, upstream commit fac8e0f57969 ("tunnels: Don't apply GRO to multiple layers of encapsulation.") seems to have been incorrectly backported into v4.1.y commit 066b300e5be4.
I have not analyzed why the function is now unused, but in the original patch it is used, unlike in the backport.
It looks like this patch fixes a bug in commit feec0cb3f20b8 ("ipv6: gro: support sit protocol"), which didn't land until v4.4, so perhaps this patch can just be dropped from 4.1.y.

../include/linux/spinlock.h:256:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized]I could not immediately find this one.
I'm not sure if full logs are available somewhere, but the line above this is probably of more interest. For example:
drivers/tty/serial/amba-pl011.c: In function 'pl011_console_write': include/linux/spinlock.h:256:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized]
Which looks like perhaps gcc is confused about the conditional locking/unlocking in this function.

PS. Apologies if I've mangled my reply, I've been having mail issues w/ vger recently, had to reconstruct Arnd's original email from an archive.

The build results for this tree get sent to these three lists:
kernel-build-reports@lists.linaro.org, linaro-kernel@lists.linaro.org, linux-rt-users@vger.kernel.org
They should all be open for subscription.

Mark might have a way of providing more verbose build logs, I don't think he has a web interface though. kernelci.org and http://arm-soc.lixom.net/buildlogs/ have some more logs, but don't build this tree.
It might be the exact warning you cite, I think I bisected this one in the past to an -rt specific commit and provided a patch, but it wasn't clear whether this was the best solution.

I do have https://builds.sirena.org.uk/ but it's just a dump of files.

Oh, right - I turned off directory enumeration on it since people were doing silly things with it :/ I should have the full logs if they're useful though.

I can easily CC you on all RT build reports if that's OK? I'd have to fiddle with the scripts a bit to do it per branch which will take longer if that'd be too much noise (and of course if you want to join the list that'd work too and be even easier for me but it's definitely a lot of reports!).
