From 7db971b235480849aa5b9209b67b62e987b3181b Mon Sep 17 00:00:00 2001 From: Ido Yariv Date: Sun, 3 Jun 2012 01:11:34 +0300 Subject: x86/platform: Introduce APIC post-initialization callback Some subarchitectures (such as vSMP) need to slightly adjust the underlying APIC structure. Add an APIC post-initialization callback to 'struct x86_platform_ops' for this purpose and use it for adjusting the APIC structure on vSMP systems.
