As mentioned elsewhere in the thread, it's in /sys/conf/NOTES.  Starting 
with 5.0, the old architecture dependent LINT file has been split in 
architecture independent (/sys/conf/NOTES) and dependent 
(/sys/${ARCH}/conf/NOTES) files.  Thus, you'll find it in 
/sys/${ARCH}/conf/LINT on 4.x.

Here's the commit that renamed LINT to NOTES from ~4.5 years ago:
http://docs.freebsd.org/cgi/mid.cgi?200006132228.PAA97611

Here's the commit that split NOTES into architecture 
independent/dependent files from ~3 years ago:
