Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:

commit 1e2d167d8faae843b80487e5026b07a135cf4147
Author: Dario Faggioli <dario.faggioli@xxxxxxxxxx>

    xen: credit2: avoid calling __update_svc_load() multiple times on the same 
vcpu
    
    by not resetting the variable that should guard against
    that at the beginning of each step of the outer loop.

commit e4c1792b589be236d68eb7930979cadb5838e097
Author: Dario Faggioli <dario.faggioli@xxxxxxxxxx>
Date:   Wed Jul 6 17:34:14 2016 +0100

    xen: credit2: when tickling, check idle cpus first
    
    If there are idle pCPUs, it's always better to try to
    "ship" the new vCPU there, instead than letting it
    preempting on a currently busy one.
    
    This commit also adds a cpumask_test_or_cycle() helper
    function, to make it easier to code the preference for
    the pCPU where the vCPU was running before.

Author: Dario Faggioli <dario.faggioli@xxxxxxxxxx>
Date:   Wed Jul 6 17:02:58 2016 +0100

    xen: credit2: do not warn if calling burn_credits more than once
    
    on the same vcpu, without NOW() having changed.
    
    This is, in fact, a legitimate use case. If it happens,
    we should just do nothing, without producing any warning
    or debug message.
    
    While there, fix style and add a couple of branching
    hints.

    xen: credit2: insert and tickle don't need a cpu parameter
    
    In fact, they always operate on the svc->processor of
    the csched2_vcpu passed to them.
    
    No functional change intended.

    xen: sched: make the 'tickled' perf counter clearer
    
    In fact, what we have right now, i.e., tickle_idlers_none
    and tickle_idlers_some, is not good enough for describing
    what really happens in the various tickling functions of
    the various scheduler.
    
    Switch to a more descriptive set of counters, such as:
     - tickled_no_cpu: for when we don't tickle anyone
     - tickled_idle_cpu: for when we tickle one or more
                         idler
     - tickled_busy_cpu: for when we tickle one or more
                         non-idler
    
    While there, fix style of an "out:" label in sched_rt.c.
