Yes, I downloaded the vanilla kernel from kernel.org and then I patched it
directly with ipipe. What kinds of patches I need to patch?
I've looked into the /arch/arm/mach-at91/irq.c
and /arch/arm/mach-at91/gipo.c, but i can't find any generic_handle_irq but
ipipe_handle_multi_irq and ipipe_handle_demuxed_irq.

Best regards,

*Eddie HUANG*
