    Subject[PATCH 0/8] ftrace: updates to tip

    The one patch I did here, will need to go to stable as well. I'll write
    up a patch against stable, and as soon as it gets into Linus's tree,
    it should also be pulled into stable as well. Without the patch, some
    archs will not be able to perform any tracing. There is an alignment
    issue that will cause the ring buffer to fail to commit any transactions.

    -- Steve

    The following patches are in:


    branch: tip/devel

    Lai Jiangshan (1):
    trace_workqueue: use percpu data for workqueue stat

    Markus Metzger (6):
    x86, ftrace, hw-branch-tracer: support hotplug cpus
    x86, ftrace, hw-branch-tracer: dump trace on oops
    x86, ftrace, hw-branch-tracer: reset trace buffer on close
    x86, ftrace, hw-branch-tracer: change trace format
    x86, ftrace, hw-branch-tracer: documentation
    x86, ds, bts: cleanup DS configuration

    Steven Rostedt (1):
    ring-buffer: fix alignment problem
