You have to get and set up Coccinelle on your own.  However, it is part of 
many Linux distributions, including ubuntu.

Afterwards, you can run make coccicheck to apply the semantic patches that 
are included in the kernel to the entire kernel.  There are some options 
to eg restrict the choice of rule, the choice of considered Linux files, 
and the format of the output.  Where possible we have taken 
decisions that are common with what is done elsewhere in the make file.

Documentation is in Documentation/coccinelle.txt

Suggestions for how to make it easier to use or the documentation more 
understandable are welcome.

thanks,
julia
