Hi Greg,
I think Kevin turned on the stable/linux-3.8.y builds but not the respective stable-rc ones, so I don't have any kernelci build results for 3.18.51-rc1, but Olof's builder has some results, including a number of warnings that are found because of a different compiler version and some that are powerpc specific:
Errors:
powerpc.pasemi_defconfig:/work/build/batch/arch/powerpc/kernel/ptrace.c:378:104: error: index 32 denotes an offset greater than size of 'u64[32][1] {aka long long unsigned int[32][1]}' [-Werror=array-bounds] /work/build/batch/arch/powerpc/kernel/ptrace.c:406:104: error: index 32 denotes an offset greater than size of 'u64[32][1] {aka long long unsigned int[32][1]}' [-Werror=array-bounds]
kernelci didn't have this one as it doesn't do powerpc builds. The fix is
f0b13816ad4f ("powerpc/ptrace: Fix out of bounds array access warning")
Warnings:
1 arch/arm/mach-cns3xxx/pcie.c:313:1: warning: the frame size of 1080 bytes is larger than 1024 bytes [-Wframe-larger-than=]
I fixed this a long time ago, but had to go through several revisions as my fix caused a regression. I'd leave it as is then, the warning is harmless here.

The driver was removed in 4.6

Fixed as a side-effect of

which unfortunately is not appropriate for -stable

both drivers are removed later. I'll follow up with fixes another day.
