So now I have this:

---
@funcmatch@
identifier func;
identifier p;
identifier state_var;
@@

  func(..., struct task_struct *p, ...
-      , long state_var
+      , int state_var
       ,...)
{
	...
}
---

Which seems to be doing roughly what I want. I probably need another
version to cover functions with reverse parameter order, and also need
to make it match functions that assign state_var to p->state (or pass it
down to another function that might do it).

Baby steps...
