[Xen-devel] [PATCHv1] x86: only check for one watchdog NMI

2015-06-22 Thread David Vrabel
Since the NMI handler can now recognize watchdog NMIs, make check_nmi_watchdog() only check for at least one watchdog NMI. This prevents false negatives caused by other processors (which may be being power managed by the BIOS) running at reduced clock frequencies. This will also slightly speed up
