Looks pretty sane from a quick scan.

- request_irq() can use GFP_KERNEL?

- show_interrupts() should use for_each_online_cpu()

<wow, kprobes support>

- do you really need __udivdi3() and friends? We struggle hard to avoid
the necessity on x86 and you should be able to leverage that advantage.

- What are these for?

+EXPORT_SYMBOL(register_dma_controller);
+EXPORT_SYMBOL(find_dma_controller);

+EXPORT_SYMBOL(clk_get);
+EXPORT_SYMBOL(clk_put);
+EXPORT_SYMBOL(clk_enable);
+EXPORT_SYMBOL(clk_disable);
+EXPORT_SYMBOL(clk_get_rate);
+EXPORT_SYMBOL(clk_round_rate);
+EXPORT_SYMBOL(clk_set_rate);
+EXPORT_SYMBOL(clk_set_parent);
+EXPORT_SYMBOL(clk_get_parent);

- Was there a ./MAINTAINERS patch? I didn't see one.

- Who stands behind this port? How do we know this isn't a patch-n-run
exercise? How do we know that the code won't rot?

- How does one build a something->avr32 cross-toolchain?

Thanks.
