NAK to that, it will mess up a lot of older drivers which still use the irq field and also those who want it to print
Look at the pt_regs change -- the irq change is similar:

The information does not go away, it is merely available via another avenue.

but pt_regs is alot less frequently used than irq - and where it's used they arent "drivers" but mostly arch level code like hw-timer handlers.

Nonetheless the -vast majority- of drivers don't use the argument at all, and the minority that do use it are not modern drivers.
