Hi,

I've been investigating why recent NetBSD/amd64 running in
qemu-system-x86_64 hangs the emulator in spllower().

I'm puzzled by two versions of this function.

In rev 1.12, one of the outs of this function is:

	...
1:
	rep
	ret
2:
	...

In rev 1.13 and latter, this is:

	...
1:=09
	ret
	ret
2:
	...

FWIW, the i386 one uses a single 'ret'.

Could someone explain the differences?
