What does this patch do to code like this (from
linux/arch/alpha/kernel/traps.c):

struct allregs {
	unsigned long regs[32];
	unsigned long ps, pc, gp, a0, a1, a2;
};

unsigned long f(struct allregs *r) {
	return r->regs[35];	// return a0
}

It's most likely invalid, but apparently people expect it to work.
