Subject: RE: linux-next: build failure after merge of the final tree
 (staging tree related)

Hi Greg,

I believe I understand the cause of the problem and would like to submit a patch to fix it. However, I am unclear on what the starting point is given that the final patch was reverted from linux-next. Do I assume that patch will be reapplied before the applying the new patch or should I provide another patch to reapply the reverted patch? Is it acceptable to submit patches generated against the head of linux-next?

Before submitting the patch, I would like to test that the patch really does fix the issue found by Stephen. Since it doesn't occur when building for x32 or x64 then I need to setup a PowerPC cross-compile tool chain. Do you have any suggestions as to where I can pull a prebuilt tool chain or do I need to build directly from the GNU sources.

Many thanks for your help
Kind regards
Chris Kelly

Thanks, Chris, care to fix this up and send me a patch?
