There is a guide here: 

http://wiki.xensource.com/xenwiki/SubmittingXenPatches

For examples, see:

http://lists.xensource.com/archives/html/xen-devel/

Also see these guidelines: 

http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt
http://linux.yyz.us/patch-format.html

I would think replying to your patch email with the performance measurement
report would help keep them together for people.
