in interrupt controllers in struct pic, and try to keep as much common code as possible. At the lowest (asm) level, this is done with CPP macros. The main structure is now struct intrsource, describing an established interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic). For quick masking, there may be a maximum of 32 sources per CPU. Sources can be assigned to any CPU in the MP case, though currently they all go to the boot CPU.
