Subject: [PATCH] xen/time: Remove unnecessary BUG_ON(preemptible()) in xen_setup_timer()
Date: Mon, 22 Dec 2014 13:33:10 -0500	[thread overview]
Message-ID: <1419273190-18821-1-git-send-email-boris.ostrovsky@oracle.com> (raw)

There is no reason for having it and, with commit 250a1ac685f1 ("x86,
smpboot: Remove pointless preempt_disable() in
native_smp_prepare_cpus()"), it prevents HVM guests from booting.
