I’ve found yet another oddity. Rather, gcc pointed it out to me, because I wasn’t paying too much attention.

this current patch which should fix RAM resume and suspend problems in 2.6.21.

It modifies the subroutine as follows:

static void tick_resume(int broadcast)
{
        struct tick_device *td = &__get_cpu_var(tick_cpu_device);
        unsigned long flags;
        int broadcast = tick_resume_broadcast();

If you don’t read nerd (or C), this is saying “Ok, so, you told me
what ‘broadcast’ is, but I’m going to ignore that and figure it out, myself.” A bit strange logic, that.

However, there is a proposed update which clears up some of this mess.

Ugh. I miss FreeBSD at times.
