Hello Chris,

the recently merged xtensa arch does not (cross) compile successfully.
I'm using 2.6.12-git7 which seems to have all patches (1-8) merged.
I did have to make some more changes because of the other changes in Andrew's tree, but wasn't sure what other patches would make it in. 
I'll submit the Xtensa patches shortly.

Thanks for the report.

then a lots of follow up errors.

It would be nice if you could fix these issues.
