From 3777a95903953c55f2309a89679b73c19ae5535b Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 3 Feb 2006 21:51:53 +0100 Subject: [PATCH] i386/x86-64: Don't ack the APIC for bad interrupts when the APIC is not enabled It's bad juju to touch the APIC when it hasn't been enabled. I also moved ack_bad_irq for x86-64 out of line following i386.
