[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. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
