Re: [Xen-devel] where does do_IRQ() be called

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

Macros defined in include/asm-x86/x86_32/asm_defns.h and instantiated in arch/x86/i8259.c. The macros implement entry stubs, the addresses of which gets poked into the CPU’s IDT in the first for() loop of i8259.c:init_IRQ().
