Previously we printed, e.g.,
do_IRQ: 0.242 No irq handler for vector (irq -1)
There's no clue about what "0.242" means, and the IRQ number, which is the
important generic information used by drivers and /proc/interrupts, is
almost an afterthought.
Change the format to this:
No handler for IRQ -1 (CPU 0 vector 0xf2)
