[PATCH] i386: apic= command line option should always be
From: "Jan Beulich" <jbeulich@novell.com> When using apic= on the kernel command line, this had no effect for machines matched by either the ACPI MADT or the MPS OEM table scan. However, when such option is specified, it should also take effect for this set of systems.
