      What happens is that bus_register needs a statically allocated lock_key
      because the last is handed in to lockdep. However, struct mem_ctl_info
      embeds struct bus_type (the whole struct, not a pointer to it) and the
      whole thing gets dynamically allocated.
      
      Fix this by using a statically allocated struct bus_type for the MC bus.

      Linus Torvalds authored
      Pull cgroup changes from Tejun Heo:
       "This contains two patches, both of which aren't fixes per-se but I
        think it'd be better to fast-track them.
      
        One removes bcache_subsys_id which was added without proper review
        through the block tree.  Fortunately, bcache cgroup code is
        unconditionally disabled, so this was never exposed to userland.  The
        cgroup subsys_id is removed.  Kent will remove the affected (disabled)
        code through bcache branch.
      
        The other simplifies task_group_path_from_hierarchy().  The function
        doesn't currently have in-kernel users but there are external code and
        development going on dependent on the function and making the function
        available for 3.11 would make things go smoother"

      Pull drm fixes from Dave Airlie:
       "This is just a regular fixes pull, mostly nouveau and i915, the i915

        Now you shouldn't wish for more patches, as the new mutex/reservation
        code found a number of problems with the qxl driver, and it currently
        makes lockdep angry, I'm working on a set of fixes for it, but its a
        bit large, I'll submit them separately later today or tomorrow once
        I've banged on them a bit more, just warning you in advance :-)"

      Fix __wait_on_atomic_t() to call the action func if the counter != 0 · 42577ca8
      David Howells authored
      Fix __wait_on_atomic_t() so that it calls the action func if the counter != 0
      rather than if the counter is 0 so as to be analogous to __wait_on_bit().
      
      Thanks to Yacine who found this by visual inspection.
      
      This will affect FS-Cache in that it will could fail to sleep correctly when
      trying to clean up after a netfs cookie is withdrawn.
