Just pointer to unsigned long and do the cast in the test setup as:

static unsigned long bad_addr;

static struct tcase = {
	...
	unsigned long *arg3;
	...
} tcases[] = {
	...
	{..., &bad_addr, ...},
	...
}

static void setup(void)
{
	invalid_addr = (unigned long)tst_get_bad_addr();
}

Then call it as prctl(..., *tc->arg3).
