This is a bugfix; please add a Fixes: tag pointing to the commit that
introduced the regression.

0x02 is unused without explanation. Either renumber TST_ASSERT_BITWISE
to 0x02 or add a comment marking the gap as reserved.

Line exceeds 80 columns. Split into an if/else block:

	if (sys_val_64 > (unsigned long long)INT_MAX)
		expected_val = (unsigned long)INT_MAX;
	else
		expected_val = (unsigned long)sys_val_64;
