Subject: [PATCH] IRQ: ease out-of-tree migration to new irq_handler prototype


Ease out-of-tree driver migration to new irq_handler prototype.
Define empty 3rd argument macro for use in multi kernel version
out-of-tree drivers going forward.  Backportable drives can do:

(in a header)
#ifndef __PT_REGS
# define __PT_REGS , struct pt_regs *regs

(in code body)
static irqreturn_t irq_handler(int irq, void *dev_id __PT_REGS)

Signed-off-by: Bill Waddington <>


Has this suggestion by Ingo Molnar been implemented?  May I
submit it?  Is this how it's done?
