[Xen-devel] [PATCH 1/3] trace: include timestamp in trace records added by HVMOP_xentrace

[David Vrabel <david.vrabel@xxxxxxxxxx>]

From: David Vrabel <david.vrabel@xxxxxxxxxx>

TRC_GUEST trace records added by the HVMOP_xentrace op are not
timestamped.  Timestamping these records is useful if only TRC_GUEST
records are enabled.
