Must I say it in each file, or in commit message?
If in commit, how about something like this:
"
Many of code in arch/c6x/include/asm and arch/c6x/lib come from linux kernel,
c6x headers (arch/c6x/include/asm) in linux kernel mainline from commit
a7f626c1948ab6178d2338831c5ffea7385e9f7f
c6x libs (arch/c6x/lib) in linux kernel mainline from
09831ca73443bd819ad7993db5409b19c899ba33
"
