eric miao 521086412e ARM: 6532/1: Allow machine to specify it's own IRQ handlers at run-time ... Normally different ARM platform has different way to decode the IRQ hardware status and demultiplex to the corresponding IRQ handler. This is highly optimized by macro irq_handler in entry-armv.S, and each machine defines their own macro to decode the IRQ number. However, this prevents multiple machine classes to be built into a single kernel. By allowing each machine to specify thier own handler, and making function pointer 'handle_arch_irq' to point to it at run time, this can be solved. And introduce CONFIG_MULTI_IRQ_HANDLER to allow both solutions to work. Comparing with the highly optimized macro of irq_handler, the new function must be written with care not to lose too much performance. And the IPI stuff on SMP is expected to move to the provided arch IRQ handler as well. The assembly code to invoke handle_arch_irq is optimized by Russell King.
