From b940d22d58c41b2ae491dca9232850f6f38f3653 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sun, 8 Oct 2006 07:43:46 -0600 Subject: [PATCH] i386/x86_64: Remove global IO_APIC_VECTOR Which vector an irq is assigned to now varies dynamically and is not needed outside of io_apic.c. So remove the possibility of accessing the information outside of io_apic.c and remove the silly macro that makes looking for users of irq_vector difficult. The fact this compiles ensures there aren't any more pieces of the old CONFIG_PCI_MSI weirdness that I failed to remove. Signed-off-by: Eric W.
