Subject: [PATCH] serverworks: IRQ routing needs no _p
Date: Fri, 11 Jan 2008 18:14:34 +0000	[thread overview]
Message-ID: <> (raw)

I can find no reason for the _p on the serverworks IRQ routing logic, and
a review of the documentation contains no indication that any such delay
is needed so lets try this

diff -u --new-file --recursive --exclude-from /usr/src/exclude linux.vanilla-2.6.24-rc6-mm1/arch/x86/pci/irq.c linux-2.6.24-rc6-mm1/arch/x86/pci/irq.c
