SubjectRE: linux-next: build failure after merge of the final tree (staging tree related)
Hi Stephen,

Many thanks for your reply. This is exactly what I needed. I have submitted a patch to fix the problem and it builds OK with the compiler you suggested below.

Kind regards
Chris Kelly

Your patches are all still in Greg's tree which I merge into linux-next every day. I have then been reverting that last patch each day. Your patch should be against Greg's tree (or your last patch) and then when the fix is in Greg's tree, I will get it in linux-next and stop reverting the other patch.

That is am x86_64 hosted powerpc64 compiler suitable for building the kernel.
