From 0e4d394fe50308f69eb061eb89de78279df1e9dc Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Mon, 26 Jun 2017 18:39:30 +0200 Subject: [PATCH] xen/x86: Don't BUG on CPU0 offlining CONFIG_BOOTPARAM_HOTPLUG_CPU0 allows to offline CPU0 but Xen HVM guests BUG() in xen_teardown_timer(). Remove the BUG_ON(), this is probably a leftover from ancient times when CPU0 hotplug was impossible, it works just fine for HVM.
