[Xen-devel] [PATCH v2 2/2] cambridge: arrange to test each new baseline

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Provide a new cr-daily-branch setting OSSTEST_BASELINES_ONLY which
causes it to only attempt to test the current baseline (if it is
untested) and never the tip version. Such tests will not result in any
push.

Add a cronjob to Cambridge which runs in this manner, ensuring that
there will usually be some sort of reasonably up to date baseline for
any given branch which can be used for comparisons in adhoc testing or
bisections.

This will also give us some data on the success of various branches on
the set of machines in Cambridge, which can be useful/interesting.
