have any ideas on why these fatal errors are showing up for these .cocci files?
I think you are in an unpleasant state and should clean up and start over.
Look around and see if you have any directories that have the names of
semantic patches and remove them.
Otherwise, it looks like you are not running these commands from the root
of the kernel directory? Because it is not finding any of the .cocci
files.
