That's Russell 8) Well, if you need IRQ0 to be real then redefining is_real_interrupt() is the correct way forward. However, Linus' policy is that IRQ0 shall be invalid at least on PCI systems, and architectures _should_ remap their real IRQ0 to some other number. Personally I don't like this. Hence why I prefer to give people the option. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core
