H A Dtrace-eventsbc535e59 Tue Feb 07 02:28:09 CST 2017 Peter Xu <peterx@redhat.com> intel_iommu: convert dbg macros to traces for inv

VT-d codes are still using static DEBUG_INTEL_IOMMU macro. That's not
good, and we should end the day when we need to recompile the code
before getting useful debugging information for vt-d. Time to switch to
the trace system. This is the first patch to do it.
