From 04b9267b15206fc902a18de1f78de6c82ca47716 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 4 Oct 2006 02:16:46 -0700 Subject: [PATCH] genirq: x86_64 irq: Remove the msi assumption that irq == vector This patch removes the change in behavior of the irq allocation code when CONFIG_PCI_MSI is defined. Removing all instances of the assumption that irq == vector. create_irq is rewritten to first allocate a free irq and then to assign that irq a vector. assign_irq_vector is made static and the AUTO_ASSIGN case which allocates an vector not bound to an irq is removed. The ioapic vector methods are removed, and everything now works with irqs. The definition of NR_IRQS no longer depends on CONFIG_PCI_MSI Signed-off-by: Eric W.
