From 629e15d245f46bef9d26199b450f882f9437a8fe Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Fri, 15 May 2009 13:05:16 -0700 Subject: [PATCH] x86, irq: update_mptable needs pci_routeirq To get all device irq routing and to save them. This is basically an implicit pci=routeirq enablement if (and on if) the update_mptable boot option (which is off by default) has been specified.
