      This reverts commit b5097e95.
      
      The original commit is buggy, we do use the registration functions
      at runtime, for instance when loading IO schedulers through sysfs.

      blkcg: fix use-after-free in __blkg_release_rcu() by making blkcg_gq refcnt an atomic_t · a5049a8a
      Tejun Heo authored
      Hello,
      
      So, this patch should do.  Joe, Vivek, can one of you guys please
      verify that the oops goes away with this patch?
      
      Jens, the original thread can be read at
      
        http://thread.gmane.org/gmane.linux.kernel/1720729
      
      The fix converts blkg->refcnt from int to atomic_t.  It does some
      overhead but it should be minute compared to everything else which is
      going on and the involved cacheline bouncing, so I think it's highly
      unlikely to cause any noticeable difference.  Also, the refcnt in
      question should be converted to a perpcu_ref for blk-mq anyway, so the
      atomic_t is likely to go away pretty soon anyway.
      
      Thanks.
      
      ------- 8< -------
      __blkg_release_rcu() may be invoked after the associated request_queue
      is released with a RCU grace period inbetween.  As such, the function
      and callbacks invoked from it must not dereference the associated
      request_queue.  This is clearly indicated in the comment above the
      function.
      
      Unfortunately, while trying to fix a different issue, 2a4fd070
      ("blkcg: move bulk of blkcg_gq release operations to the RCU
      callback") ignored this and added [un]locking of @blkg->q->queue_lock
      to __blkg_release_rcu().  This of course can cause oops as the
      request_queue may be long gone by the time this code gets executed.

      The request_queue locking was added because blkcg_gq->refcnt is an int
      protected with the queue lock and __blkg_release_rcu() needs to put
      the parent.  Let's fix it by making blkcg_gq->refcnt an atomic_t and
      dropping queue locking in the function.
      
      Given the general heavy weight of the current request_queue and blkcg
      operations, this is unlikely to cause any noticeable overhead.
      Moreover, blkcg_gq->refcnt is likely to be converted to percpu_ref in
      the near future, so whatever (most likely negligible) overhead it may
      add is temporary.

      block: remove WQ_POWER_EFFICIENT from kblockd · 28747fcd
      Matias Bjørling authored
      blk-mq issues async requests through kblockd. To issue a work request on
      a specific CPU, kblockd_schedule_delayed_work_on is used. However, the
      specific CPU choice may not be honored, if the power_efficient option
      for workqueues is set. blk-mq requires that we have strict per-cpu
      scheduling, so it wont work properly if kblockd is marked
      POWER_EFFICIENT and power_efficient is set.
      
      Remove the kblockd WQ_POWER_EFFICIENT flag to prevent this behavior.
      This essentially reverts part of commit 695588f9, which added
      the WQ_POWER_EFFICIENT marker to kblockd.

       "This is a small follow-up to the larger ARM SoC updates merged last
        week, almost entirely for the keystone platform.
      
        The main change here is to use the new dma-ranges parsing code that
        came in through Russell's ARM tree.  This allows the keystone platform
        to do cache-coherent DMA and to finally support all the available
        physical memory when LPAE is enabled.
      
        Aside from this, the keystone reset driver has been rewritten, and
        there is a small bug fix to allow building the orion5x platform again"

           shared tag space.  Before we failed with EINVAL if a too large tag
           depth was specified, now we truncate it and pass back the actual

      reiserfs: Fix compilation breakage with CONFIG_REISERFS_CHECK · 19ef1229
      Jan Kara authored
      There was a bug in debug printout when CONFIG_REISERFS_CHECK was
      enabled so one of the assertions in do_balan.c didn't compile. Fix it.

      Linus Torvalds authored
      Pull powerpc updates from Ben Herrenschmidt:
       "Here is the bulk of the powerpc changes for this merge window.  It got
        a bit delayed in part because I wasn't paying attention, and in part
        because I discovered I had a core PCI change without a PCI maintainer
        ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
        probably improve it later and I didn't want to rebase to add his ack.
      
        There is going to be a bit more next week, essentially fixes that I
        still want to sort through and test.
      
        The biggest item this time is the support to build the ppc64 LE kernel
        with our new v2 ABI.  We previously supported v2 userspace but the
        kernel itself was a tougher nut to crack.  This is now sorted mostly
        thanks to Anton and Rusty.
      
        We also have a fairly big series from Cedric that add support for
        64-bit LE zImage boot wrapper.  This was made harder by the fact that
        traditionally our zImage wrapper was always 32-bit, but our new LE
        toolchains don't really support 32-bit anymore (it's somewhat there
        but not really "supported") so we didn't want to rely on it.  This
        meant more churn that just endian fixes.
      
        This brings some more LE bits as well, such as the ability to run in
        LE mode without a hypervisor (ie. under OPAL firmware) by doing the
        right OPAL call to reinitialize the CPU to take HV interrupts in the
        right mode and the usual pile of endian fixes.
      
        There's another series from Gavin adding EEH improvements (one day we
        *will* have a release with less than 20 EEH patches, I promise!).
      
        Another highlight is the support for the "Split core" functionality on
        P8 by Michael.  This allows a P8 core to be split into "sub cores" of
        4 threads which allows the subcores to run different guests under KVM
        (the HW still doesn't support a partition per thread).
      
        And then the usual misc bits and fixes ..."
