Seriously, is that all?
Are you filtering out old warnings to just see regressions or is that all that is left to fix now?

../drivers/net/ethernet/amd/nmclan_cs.c:624:3: warning: 'pcmcia_request_exclusive_irq' is deprecated (declared at ../include/pcmcia/ds.h:213) [-Wdeprecated-declarations]
A few people have tried to work around this one in the past, it comes down to proving that mace_interrupt() is safe when called on a shared interrupt line, and then replacing pcmcia_request_exclusive_irq() with pcmcia_request_irq, and finally removing pcmcia_request_exclusive_irq() from the kernel, as this is the last user.
I think it's safe, but I'm not totally convinced.

I guess we should try to find a new cns3xxx maintainer
I'd be more than happy to hand it over. As far as I know, OpenWRT is a major user of cns3xxx nowadays, so Cc'ing some of the active folks.
Anton no longer has access to the hardware as far as I know,
Yup.
and the patch I made for this needs to be tested.
Fwiw, it looked really good.
Thanks!

I agree that would be best. Also, looking at the code that sits in the OpenWRT git, most of the cns3xxx patches should just get merged upstream, I'll take them as soon as someone can write a changelog for them.
The SMP support, in particular the fiq usage is probably the only thing that will need a few review rounds.
and the patch I made for this needs to be tested.
Fwiw, it looked really good.

No filtering, we're actually doing pretty well (unless you turn on sparse for the builds at which point it gets miserable). Or the compiler is terrible at catching errors though I didn't change that recently. I imagine it will get worse on at least ARMv8 when PCI is enabled.

It's fixed in -next, I sent the patches just before the merge window so they didn't make it into mainline yet.

Right, or my hack is at least no less safe than the current code.
