Of the following, the original is clearly outdated so we can all agree that
can go.  I'm not real found of Linus' style either.  What's wrong with the
two traditional forms?

/* ============== original ============== */
static unsigned long
insert_bba (insn, value, errmsg)
	unsigned long insn;
	long value;
	const char **errmsg;
{
	return insn | (((insn >> 16) & 0x1f) << 11);
}

/* ============== linus ============== */
static unsigned long insert_bba(
	unsigned long insn;
	long value;
	const char **errmsg;
)
{
	return insn | (((insn >> 16) & 0x1f) << 11);
}

/* ============== traditional ============== */
static unsigned long
insert_bba(unsigned long insn; long value; const char **errmsg)
{
	return insn | (((insn >> 16) & 0x1f) << 11);
}

/* ============== traditional (lotso args) ============== */
static unsigned long
insert_bba(
	register unsigned const int some_big_fat_variable_name;
	unsigned long insn;
	long value;
	const char **errmsg)
{
	return insn | (((insn >> 16) & 0x1f) << 11);
}
