While I see the list of subsystems there, how do I find out the (wrong?)
current bug's subsystem?
Thanks for fixing!

[hoping this will be read by a human and not one of these AI]
You keep sending me these reports because the GIC is in a
stacktrace.
But the root cause it probably somewhere else, as the multiple runs of
the same kernel result in very different exceptions, most of which
never reach the point where it explodes in your stacktrace. Here's one
of them:

So not much to do with the GIC, but more to do with general stack
overflow/corruption. I'd appreciate it if you could stop barking up
the wrong tree and get someone who is still interested in 32bit ARM to
look into it.
Thanks,

The report was attributed to `drivers/irqchip/irq-gic.c` and
`./scripts/get_maintainer.pl -f drivers/irqchip/irq-gic.c` gives
[email protected] (open list:ARM/RISC-V/RENESAS ARCHITECTURE)
as one of the output results.

In this particular case, syzbot was not able to determine any
subsystems (I've sent a fix) and just picked the output of the
get_maintainer.pl script.

Oh, right, there's a small quirk for renesas,emev in the GIC driver.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
