Odd...if it is only kzalloc, kmalloc, etc.. I wonder if it is
resolved if you include linux/slab.h in include/dahdi/kernel.h.
Something like:

  diff --git a/include/dahdi/kernel.h b/include/dahdi/kernel.h
  index f2f9ec5..c19aec5 100644
  --- a/include/dahdi/kernel.h
  +++ b/include/dahdi/kernel.h
  @@ -43,6 +43,7 @@
   #include <linux/cdev.h>
   #include <linux/module.h>
   #include <linux/ioctl.h>
  +#include <linux/slab.h>
   #include <linux/hdlc.h>

Does that resolve it for you?
