If it's not implemented I'd expect that either this option is not listed
when you run the program without arguments or that cpus 1-3 have nointr
by default and an attempt to set intr fails.

Why do you sepcial case cpu 0 here?
Isn't the problem that you disable cpus where interrupts are routed to
(w/o rerouting those interrupts)?
This nowdadys is not the same as disabling interrupts on cpu 0 (and also
is a machine dependent thing).
We could either add some (more or lesss automatic) rewiring of interrupts
code to cpuctl - or (much simpler) write this off as pilot error.

Yes, it could be more intelligent. But "cpuctl nointr 0" still hangs my
amd64 system -- and even if I've enabled interrupts for the other != 0 CPUs.

The point is: depending on your system it could be *any* cpuctl nointr $N
that hangs it.
You are just lucky that it is *just* 0 that hangs it for you.

Then I suppose the whole "nointr" code is broken and completely unsafe.

Committed By: rin

src/sys/kern: kern_cpu.c
Log Message:
PR kern/45117
Work around regression introduced in rev 1.92:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/kern_cpu.c#rev1.92
by which ``cpuctl offline n'' became broken on architectures without
__HAVE_INTR_CONTROL (i.e., everything other than alpha and x86);
cpu_setintr() always fails on these archs, and we had neglected
return value from that function until rev 1.91.
XXX
As martin pointed out in the PR, I'm not sure whether fix in rev 1.92
itself is correct or not. Insert XXX comment referring the PR there....
