From 48fd672feeff15417fc6e135b221c2e07a5d67a2 Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Thu, 12 Nov 2009 13:02:27 +0000 Subject: [PATCH] Revert 20045:db1890f07661 "Revert alloc_idle_vcpu()..." The old implementation of alloc_idle_vcpu() is unnecessary since arch-specific code ensures that a single idle domain supports NR_CPUS vcpus, despite the usual limit of MAX_VIRT_CPUS for ordinary domains.
