From 1595f452f3d8daa066bfd3ba4120754bed3329e1 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 14 Oct 2007 22:57:45 +0200 Subject: clockevents: introduce force broadcast notifier The 64bit SMP bootup is slightly different to the 32bit one. It enables the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E systems have the C1E feature flag only set in the secondary CPU. Due to the early enable of the boot CPU local APIC timer the APIC timer is registered as a fully functional device. When we detect the wreckage during the bringup of the secondary CPU, we need to force the boot CPU into broadcast mode. Add a new notifier reason and implement the force broadcast in the clock events layer.
