For example to process 6 SmPL patches at the same time:
make coccicheck PARALLEL=6
Results are held in /tmp until the scripts finish. By doing this the
script is able to collate the results from each SmPL patch instead of
interleaving them in the output.
You might try adding support for gnu parallel instead.

That is a very interesting and useful tool :) I'd never heard of it
before. The man page scares me a little bit - lots of options are marked
as "alpha testing," but the ones i tried seemed to work fine. Anyway,
without any modifications to Coccinelle, it is possible to do this:
ls scripts/coccinelle/*/*.cocci | parallel -j+0 make coccicheck COCCI={}
MODE=patch
it seems to behave mostly like my patch, but doesn't cleanup quite as
well if you decide to kill it with ctrl-c (it leaves instances of spatch
running). On the upside, it is up to 3 seconds faster than my patch
(because my patch waits 3 seconds before checking on the number of jobs
that are running).
