The patch titled
kernel: shut up the IRQ mismatch messages
has been removed from the -mm tree. Its filename was
kernel-shut-up-the-irq-mismatch-messages.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: kernel: shut up the IRQ mismatch messages
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
The problem is various drivers legally validly and sensibly try to claim
IRQs but the kernel insists on vomiting forth a giant irrelevant debugging
spew when the types clash.
Edit kernel/irq/manage.c go down to mismatch: in setup_irq() and ifdef out
the if clause that checks for mismatches. It'll then just do the right
thing and work sanely.
For the current -mm kernel this will do the trick (and moves it into shared
irq debugging as in debug mode the info spew is useful). I've had a
variant of this in my private tree for some time as I got fed up on the
mess on boxes where old legacy IRQs get reused.
