FAOD I think this is fine with George's ack.

[Xen-devel] [PATCH v2 07/10] tools: tracing: handle more scheduling related events.

[Dario Faggioli]

There are some scheduling related trace records that
are not being taken care of (and hence only dumped as
raw records).

Some of them are being introduced in this series, while
other were just neglected by previous patches.

Add support for them.

Changes from v1:
 * only the one made necessary by the packing done to Credit1 records. Those
   were requested by George himself, and the effect on this patch is small,
   and purely mechanic, so I decided to keep his Ack.
