Good. Are you going to fix those? I thought I did a powerpc defconfig build of arch/powerpc/ and I believe it finished without error, but I'm pleased it found some defects. I think it's now marked "rejected" in patchwork. Perhaps it'd better to mark it "deferred" instead. ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

Hmm, I'd be surprised, but it might depend on the exact config / compiler etc. > I think it's now marked "rejected" in patchwork. > Perhaps it'd better to mark it "deferred" instead. I can do that.
