From 4267c41a458cd7d287dc8031468fc385c2f5b2c3 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Thu, 24 May 2007 13:09:41 +0300 Subject: [PATCH] KVM: Tune hotplug/suspend IPIs The hotplug IPIs can be called from the cpu on which we are currently running on, so use on_cpu(). Similarly, drop on_each_cpu() for the suspend/resume callbacks, as we're in atomic context here and only one cpu is up anyway.
