I don't know - we need to find a davem to answer that question.
egcs-1.1.2 has a problem with the percpu infrastructure - it
fails to put the right things in the right sections. The
workaround for that is to ensure that the percpu data structures
are always initialised at the definition site:
/* Some compilers disobey section attribute on statics when not
initialized -- RR */
static struct tasklet_head tasklet_vec __per_cpu_data = { NULL };
static struct tasklet_head tasklet_hi_vec __per_cpu_data = { NULL };
Note the (otherwise unneeded) `= { NULL }'. The result of getting
this wrong is a nasty and subtly-dead kernel.
It's not a very happy state of affairs. I'll be using
2.91.66 on x86 from now on, so any problems (in the stuff
which I build and test) will be picked up.
