Build error with realtime patch on ppc platform

Build error with realtime patch on ppc platform

[Tate, Patrick O]

Hi Ingo

My name is Pat Tate and I was trying to build a kernel with the realtime
patch on a powerpc. We are using the YDL 4.1 distribution.
I pulled down the linux 2.6.29-rc6 with the realtime
patch-2.6.29-rc6-rt3.

But after applying the patch and executing the make I get the following
error in the spinlock_types.h

I was told by Eduard Munteanu that you are the contact in the patch file
so I thought I'd pass it by you and
See if you have an answer or some ideas.

If not would you know who might be a good contact to maybe work thru
this error.

Thanks for any help 

Pat

I have not yet found the time to bring powerpc -rt support back to
life. We dropped it due to lack of time when we ported it forward from
2.6.26 to 2.6.29. It's work in progress. I have some bits and pieces
done already and will integrate them into the next release. That
should be at least a halfways reasonable starting point.

Thanks,
