PATCH 1/1 enable i386 SMP kernel build without ioapic support

Hi all again,

this trivial patch (against 2.5.59) moves enable_NMI_through_LVT0() function from i386/kernel/io_apic.c to i386/kernel/apic.c

This patch allows building SMP kernel without ioapic support included, as needed for visws subarch.

Please consider applying.

Best regards.
