- kernel-shut-up-the-irq-mismatch-messages.patch removed from -mm tree

[akpm]

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@lxorguk.ukuu.org.uk>

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.
