Quick grep of the sys/ofed immediately shows the following:

sys/ofed/include/linux/wait.h:#include <sys/param.h>
sys/ofed/include/linux/wait.h:#include <sys/systm.h>
sys/ofed/include/linux/wait.h:#include <sys/sleepqueue.h>
sys/ofed/include/linux/wait.h:#include <sys/kernel.h>
sys/ofed/include/linux/wait.h:#include <sys/proc.h>

ys/ofed/include/linux/timer.h:#include <sys/callout.h>
sys/ofed/include/linux/types.h:#include <sys/cdefs.h>
sys/ofed/include/linux/types.h:#include <sys/types.h>
sys/ofed/include/linux/types.h:#include <sys/param.h>
sys/ofed/include/linux/types.h:#include <sys/systm.h>

and so on.
