Subject: [PATCH] enable i386 SMP kernel build without ioapic support
Date: Fri, 31 Jan 2003 11:34:45 +0300 [thread overview]
Message-ID: <20030131083445.GB9682@pazke> (raw)
[-- Attachment #1: Type: text/plain, Size: 385 bytes --]
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.
