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:
