We thought about this but since we were adding both the APIs filter_irq_stacks & in_irqentry_text 
in header file so we thought of defining empty definition for both as both the APIs are accessible
to the module who is going to include header file.

If you think empty definition of in_irqentry_text() is not requited then we will modify & resend the
patch.

Thanks & Regards,
