Creating patches using 'diff'

[brian . auld]

This is more of a question than a bug. I could not find a mailing list for 
'diff' or 'patch', so I am posing the question to this list. I'm creating 
rather large patches of the linux kernel source tree. I want to ignore $Header 
information so only actual code changes get picked up in the diff. I have read 
the man pages and googled extensively and cannot find any information on how to 
do this. My patch is littered with diffs that are picked up from files that 
only differ in their header information. Unfortunately, I do/did not manage the 
repositories (MKS) where this source tree was created and tracked, so the 
$Header differences are unavoidable as far I know.

Is it possible to create a patch file using diff that ignores differences in 
$Header entries?

Thanks,

Brian
