Wow, indeed. With just the attached patch, I get exactly one OOPS
now--- in ssc_free(), which I think is getting called because
atmel_ssc_modinit() is racing with something.

So I went ahead and tried it anyway:
$ git diff init/main.c
diff --git a/init/main.c b/init/main.c

The code was looking for this in cpu_features, not mmu_features. Fix this.

Guys:
My recent post, "Requesting a GPIO that hasn't been registered yet", and
Anton's reply thereto (thanks, Anton!) on linuxppc-dev got me thinking
about the problem of dependencies between devices in different classes,
and/or between drivers/devices in general. I'd like to float an idea to

In the interest of making it easier for someone to help, I've been able
to replicate the problem with the following minimal kernel module:

static unsigned int cpld_virq = NO_IRQ;
