IB/rdmavt: Add support for tracing events This patch adds support of tracing events using the kernels built-in event tracing infrastructure. This can be extended to provide a wide range of trace and debug capabilities which have a negligible impact on performance when enabled. These should be preferred over the use of the rvt_pr* functions.

IB/{rdmavt, hfi1, qib}: Remove get_card_name() downcall rdmavt has a down call to client drivers to retrieve a crafted card name. This name should be the IB defined name. Rather than craft the name each time it is needed, simply retrieve the IB allocated name from the IB device. Update the function name to reflect its application. Clean up driver code to match this change. Reviewed-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Michael J.
