From 54ac14a8e982ae6c7ac71ee2b0d0173b974509e2 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 17 Nov 2008 15:19:53 -0800 Subject: x86: fix wakeup_cpu with numaq/es7000, v2, fix Impact: fix wakeup_secondary_cpu with hotplug We can not put that into x86_quirks, because that is __initdata. So try to move that to genapic, and add update_genapic in x86_quirks. later we even could use that stub to: 1. autodetect CONFIG_ES7000_CLUSTERED_APIC 2. more correct inquire_remote_apic with apic_verbosity setting.
