v2:
- for patch 1: replace tabs, add trivial comment [Markus]
  (I didn't add much comment otherwise I'll need to duplicate what's
   there in error_report())
- add patch 2

Patch 1 introduce the helpers.

Patch 2 use it to replace VT-d trace_vtd_err().

Please review.  Thanks.

Peter Xu (2):
  qemu-error: introduce {error|warn}_report_once
  intel-iommu: start to use error_report_once
