    x86: print relevant (tail) part of filename for warnings and crashes
    In particular when the origin construct is in a header file (and
    hence the file name is an absolute path instead of just the file name
    portion) the information can otherwise become rather useless when the
    build tree isn't sitting relatively close to the file system root.

    credit: unpause parked vcpu before destroying it
    A capped out vcpu must be unpaused in case of moving it to another cpupool,

    sched: fix race between sched_move_domain() and vcpu_wake()
    sched_move_domain() changes v->processor for all the domain's VCPUs.
    If another domain, softirq etc. triggers a simultaneous call to
    vcpu_wake() (e.g., by setting an event channel as pending), then
    vcpu_wake() may lock one schedule lock and try to unlock another.
    vcpu_schedule_lock() attempts to handle this but only does so for the
    window between reading the schedule_lock from the per-CPU data and the
    spin_lock() call.  This does not help with sched_move_domain()
    changing v->processor between the calls to vcpu_schedule_lock() and
    Fix the race by taking the schedule_lock for v->processor in

    Use vcpu_schedule_lock_irq() (which now returns the lock) to properly
    retry the locking should the to be used lock have changed in the course
    of acquiring it (issue pointed out by George Dunlap).
    Add a comment explaining the state after the v->processor adjustment.

    fix locking in cpu_disable_scheduler()
    So commit eedd6039 ("scheduler: adjust internal locking interface")
    uncovered - by now using proper spin lock constructs - a bug after all:
    When bringing down a CPU, cpu_disable_scheduler() gets called with
    interrupts disabled, and hence the use of vcpu_schedule_lock_irq() was
    never really correct (i.e. the caller ended up with interrupts enabled
    despite having disabled them explicitly).
    Fixing this however surfaced another problem: The call path
    vcpu_migrate() -> evtchn_move_pirqs() wants to acquire the event lock,
    which however is a non-IRQ-safe once, and hence check_lock() doesn't
    like this lock to be acquired when interrupts are already off. As we're
    in stop-machine context here, getting things wrong wrt interrupt state
    management during lock acquire/release is out of question though, so
    the simple solution to this appears to be to just suppress spin lock
    debugging for the period of time while the stop machine callback gets

    scheduler: adjust internal locking interface
    Make the locking functions return the lock pointers, so they can be
    passed to the unlocking functions (which in turn can check that the
    lock is still actually providing the intended protection, i.e. the
    parameters determining which lock is the right one didn't change).
    Further use proper spin lock primitives rather than open coded
    local_irq_...() constructs, so that interrupts can be re-enabled as
    appropriate while spinning.
