Shouldn't this be being fixed in the headers? It looks like they reference and disagree with each other on Exynos (my primary development platform is S3C6410 based so I'd notice if it was a generic Samsung issue.
Pasting the error message isn't really that useful unless the fix is obvious, it's better to explain in words what's wrong.
I had sent the initial patch trying to fix this in the headers and it worked for exynos4 config. However Kukjin pointed out that the patch created similar errors with 2410 and 6400 configs. Fixing it further in the headers did not look quite straight forward as there are many headers trying to include one another. Hence I felt it is better handled in the current way. I understand i should have added this information in the commit message. Below is the link for your reference that provides the complete discussion.

Please let me know your opinion about this.
I also agree with Mark's opinion and current Sachin's approach cannot avoid whole similar build error.
Thanks.
