      Pull block layer fixes from Jens Axboe:
       "A small collection of fixes that should go in before -rc1.  The pull
        request contains:
      
         - A two patch fix for a regression with block enabled tagging caused
           by a commit in the initial pull request.  One patch is from Martin
           and ensures that SCSI doesn't truncate 64-bit block flags, the
           other one is from me and prevents us from double using struct
           request queuelist for both completion and busy tags.  This caused
           anything from a boot crash for some, to crashes under load.
      
         - A blk-mq fix for a potential soft stall when hot unplugging CPUs
           with busy IO.
      
         - percpu_counter fix is listed in here, that caused a suspend issue
           with virtio-blk due to percpu counters having an inconsistent state
           during CPU removal.  Andrew sent this in separately a few days ago,
           but it's here.  JFYI.
      
         - A few fixes for block integrity from Martin.
      
         - A ratelimit fix for loop from Mike Galbraith, to avoid spewing too
           much in error cases"

      Martin bisected and found this to be the problem patch;
      
      	commit 6d113398
      	Author: Jan Kara <jack@suse.cz>
      	Date:   Mon Feb 24 16:39:54 2014 +0100
      
      	    block: Stop abusing rq->csd.list in blk-softirq
      
      and the problem was immediately apparent. The patch states that
      it is safe to reuse queuelist at completion time, since it is
      no longer used. However, that is not true if a device is using
      block enabled tagging. If that is the case, then the queuelist
      is reused to keep track of busy tags. If a device also ended
      up using softirq completions, we'd reuse ->queuelist for the
      IPI handling while block tagging was still using it. Boom.
      
      Fix this by adding a new ipi_list list head, and share the
      memory used with the request hash table. The hash table is
      never used after the request is moved to the dispatch list,
      which happens long before any potential completion of the
      request. Add a new request bit for this, so we don't have
      cases that check rq->hash while it could potentially have
      been reused for the IPI completion.

      ASoC: Fixes for v3.15
      
      A smattering of device specific fixes, nothing stands out here except
      for the multiplatform fixes for Samsung and the device IDs being added
      by Stephen Warren - there's no real code changes from those and they
      give better robustness to the enumeration with DT.

      Pull i2c updates from Wolfram Sang:
       "Here is the pull request from the i2c subsystem.  It got a little
        delayed because I needed to wait for a dependency to be included
        (commit b424080a: "reset: Add optional resets and stubs").  Plus,
        I had some email problems.  All done now, the highlights are:
      
         - drivers can now deprecate their use of i2c classes.  That shouldn't
           be used on embedded platforms anyhow and was often blindly
           copy&pasted.  This mechanism gives users time to switch away and
           ultimately boot faster once the use of classes for those drivers is
           gone for good.
      
         - new drivers for QUP, Cadence, efm32
      
         - tracepoint support for I2C and SMBus
      
         - bigger cleanups for the mv64xxx, nomadik, and designware drivers
      
        And the usual bugfixes, cleanups, feature additions.  Most stuff has
        been in linux-next for a while.  Just some hot fixes and new drivers
        were added a bit more recently."

      Pull more powerpc updates from Ben Herrenschmidt:
       "Here are a few more powerpc things for you.
      
        So you'll find here the conversion of the two new firmware sysfs
        interfaces to the new API for self-removing files that Greg and Tejun
        introduced, so they can finally remove the old one.
      
        I'm also reverting the hwmon driver for powernv.  I shouldn't have
        merged it, I got a bit carried away here.  I hadn't realized it was
        never CCed to the relevant maintainer(s) and list(s), and happens to
        have some issues so I'm taking it out and it will come back via the
        proper channels.
      
        The rest is a bunch of LE fixes (argh, some of the new stuff was
        broken on LE, I really need to start testing LE myself !) and various
        random fixes here and there.
      
        Finally one bit that's not strictly a fix, which is the HVC OPAL
        change to "kick" the HVC thread when the firmware tells us there is
        new incoming data.  I don't feel like waiting for this one, it's

      futex: avoid race between requeue and wake · 69cd9eba
      Linus Torvalds 提交于
      Jan Stancek reported:
       "pthread_cond_broadcast/4-1.c testcase from openposix testsuite (LTP)
        occasionally fails, because some threads fail to wake up.
      
        Testcase creates 5 threads, which are all waiting on same condition.
        Main thread then calls pthread_cond_broadcast() without holding mutex,
        which calls:
      
            futex(uaddr1, FUTEX_CMP_REQUEUE_PRIVATE, 1, 2147483647, uaddr2, ..)
      
        This immediately wakes up single thread A, which unlocks mutex and
        tries to wake up another thread:
      
            futex(uaddr2, FUTEX_WAKE_PRIVATE, 1)
      
        If thread A manages to call futex_wake() before any waiters are
        requeued for uaddr2, no other thread is woken up"
      
      The ordering constraints for the hash bucket waiter counting are that
      the waiter counts have to be incremented _before_ getting the spinlock
      (because the spinlock acts as part of the memory barrier), but the
      "requeue" operation didn't honor those rules, and nobody had even
      thought about that case.
      
      This fairly simple patch just increments the waiter count for the target
      hash bucket (hb2) when requeing a futex before taking the locks.  It
      then decrements them again after releasing the lock - the code that
      actually moves the futex(es) between hash buckets will do the additional
      required waiter count housekeeping.

      This was caused by that 'sd->groups == NULL' after building groups, which
      was caused by the empty 'sd->span'.
      
      The cpu's domain contained nothing because the cpu was assigned to a wrong
      node, due to the following unfortunate sequence of events:
      
      1. The hypervisor sent a topology update to the guest OS, to notify changes
         to the cpu-node mapping. However, the update was actually redundant - i.e.,
         the "new" mapping was exactly the same as the old one.
      
      2. Due to this, the 'updated_cpus' mask turned out to be empty after exiting
         the 'for-loop' in arch_update_cpu_topology().
      
      3. So we ended up calling stop-machine() with an empty cpumask list, which made
         stop-machine internally elect cpumask_first(cpu_online_mask), i.e., CPU0 as
         the cpu to run the payload (the update_cpu_topology() function).
      
      4. This causes update_cpu_topology() to be run by CPU0. And since 'updates'
         is kzalloc()'ed inside arch_update_cpu_topology(), update_cpu_topology()
         finds update->cpu as well as update->new_nid to be 0. In other words, we
         end up assigning CPU0 (and eventually its siblings) to node 0, incorrectly.
      
      Along with the following wrong updating, it causes the sched-domain rebuild
      code to break and crash the system.
      
      Fix this by skipping the topology update in cases where we find that
      the topology has not actually changed in reality (ie., spurious updates).

      powerpc/le: Avoid creatng R_PPC64_TOCSAVE relocations for modules. · d3d35d95
      Tony Breeds 提交于
      When building modules with a native le toolchain the linker will
      generate R_PPC64_TOCSAVE relocations when it's safe to omit saving r2 on
      a plt call.  This isn't helpful in the conext of a kernel module and the
      kernel will fail to load those modules with an error like:
      	nf_conntrack: Unknown ADD relocation: 109
      
      This patch tells the linker to avoid createing R_PPC64_TOCSAVE
      relocations allowing modules to load.

      arch/powerpc: Use RCU_INIT_POINTER(x, NULL) in platforms/cell/spu_syscalls.c · 282efb70
      Monam Agarwal 提交于
      Here rcu_assign_pointer() is ensuring that the
      initialization of a structure is carried out before storing a pointer
      to that structure.
      So, rcu_assign_pointer(p, NULL) can always safely be converted to
      RCU_INIT_POINTER(p, NULL).

      powerpc/book3s: Fix mc_recoverable_range buffer overrun issue. · 6e556b47
      Mahesh Salgaonkar 提交于
      Currently we wrongly allocate mc_recoverable_range buffer (to hold
      recoverable ranges) based on size of the property "mcheck-recoverable-ranges".
      This results in allocating less memory to hold available recoverable range
      entries from /proc/device-tree/ibm,opal/mcheck-recoverable-ranges.
      
      This patch fixes this issue by allocating mc_recoverable_range buffer based
      on number of entries of recoverable ranges instead of device property size.
      Without this change we end up allocating less memory and run into memory
      corruption issue.
