      Pull superh tracing fix from Steven Rostedt:
       "It's been reported that function tracing does not work on the sh
        architecture because gcc 4.8 for superH does not support -m32, and the
        recordmcount.pl script adds "-m32" when re-compiling the object files
        with the mcount locations.
      
        I was not able to reproduce this problem, as it seems that -m32 works
        fine for my cross compiler gcc 4.6.3, but I have to assume that -m32
        was deprecated somewhere between 4.6 and 4.8.  As it still seems to
        compile fine without -m32, I have no reason not to add this patch, as
        having -m32 seems to cause trouble for others"

      ARM: 8292/1: mm: fix size rounding-down of arm_add_memory() function · 909ba297
      Masahiro Yamada authored
      
      
      The current rounding of "size" is wrong:
      
       - If "start" is sufficiently near the next page boundary, "size"
         is decremented by more than enough and the last page is lost.
      
       - If "size" is sufficiently small, it is wrapped around and gets
         a bogus value.

      - Remove duplicated machine checking.
        . It seems that this code was added when you merged 'v3.18-rc7' into
          drm-next. commit id : e8115e79
      - Fix hdmiphy reset.
        . Exynos hdmi has two interfaces to control hdmyphy, one is I2C, other
          is APB bus - memory mapped I/O. So this patch makes hdmiphy reset
          to be done according to interfaces, I2C or APB bus.
      - And add some exception codes.

      Pull workqueue fix from Tejun Heo:
       "The xfs folks have been running into weird and very rare lockups for
        some time now.  I didn't think this could have been from workqueue
        side because no one else was reporting it.  This time, Eric had a
        kdump which we looked into and it turned out this actually was a
        workqueue bug and the bug has been there since the beginning of
        concurrency managed workqueue.
      
        A worker pool ensures forward progress of the workqueues associated
        with it by always having at least one worker reserved from executing
        work items.  When the pool is under contention, the idle one tries to
        create more workers for the pool and if that doesn't succeed quickly
        enough, it calls the rescuers to the pool.
      
        This logic had a subtle race condition in an early exit path.  When a
        worker invokes this manager function, the function may return %false
        indicating that the caller may proceed to executing work items either
        because another worker is already performing the role or conditions
        have changed and the pool is no longer under contention.
      
        The latter part depended on the assumption that whether more workers
        are necessary or not remains stable while the pool is locked; however,
        pool->nr_running (concurrency count) may change asynchronously and it
        getting bumped from zero asynchronously could send off the last idle
        worker to execute work items.
      
        The race window is fairly narrow, and, even when it gets triggered,
        the pool deadlocks iff if all work items get blocked on pending work
        items of the pool, which is highly unlikely but can be triggered by
        xfs.
      
        The patch removes the race window by removing the early exit path,
        which doesn't server any purpose anymore anyway"

      mfd: rtsx_usb: Fix runtime PM deadlock · b166010f
      Roger Tseng authored
      sd_set_power_mode() in derived module drivers/mmc/host/rtsx_usb_sdmmc.c
      acquires dev_mutex and then calls pm_runtime_get_sync() to make sure the
      device is awake while initializing a newly inserted card. Once it is
      called during suspending state and explicitly before rtsx_usb_suspend()
      acquires the same dev_mutex, both routine deadlock and further hang the
      driver because pm_runtime_get_sync() waits the pending PM operations.
      
      Fix this by using an empty suspend method. mmc_core always turns the
      LED off after a request is done and thus it is ok to remove the only
      rtsx_usb_turn_off_led() here.

      mfd: tps65218: Make INT[12] and STATUS registers volatile · 773328da
      Felipe Balbi authored
      STATUS register can be modified by the HW, so we
      should bypass cache because of that.
      
      In the case of INT[12] registers, they are the ones
      that actually clear the IRQ source at the time they
      are read. If we rely on the cache for them, we will
      never be able to clear the interrupt, which will cause
      our IRQ line to be disabled due to IRQ throttling.

      mfd: da9052-core: Fix platform-device id collision · b3f6c73d
      Fabio Estevam authored
      Allow multiple DA9052 regulators be registered by registering with
      PLATFORM_DEVID_AUTO instead of PLATFORM_DEVID_NONE.
      
      The subdevices are currently registered with PLATFORM_DEVID_NONE, which
      will cause a name collision on the platform bus when multiple regulators
      are registered:

      As dts files have been reorganised under vendor subdirs, dtb files
      cannot be removed with "make distclean" now. Thus, this patch moves
      dtb files under archclean rule and removes unnecessary entries.

      module: fix race in kallsyms resolution during module load success. · c7496379
      Rusty Russell authored
      
      
      The kallsyms routines (module_symbol_name, lookup_module_* etc) disable
      preemption to walk the modules rather than taking the module_mutex:
      this is because they are used for symbol resolution during oopses.
      
      This works because there are synchronize_sched() and synchronize_rcu()
      in the unload and failure paths.  However, there's one case which doesn't
      have that: the normal case where module loading succeeds, and we free
      the init section.
      
      We don't want a synchronize_rcu() there, because it would slow down
      module loading: this bug was introduced in 2009 to speed module
      loading in the first place.
      
      Thus, we want to do the free in an RCU callback.  We do this in the
      simplest possible way by allocating a new rcu_head: if we put it in
      the module structure we'd have to worry about that getting freed.

      module: remove mod arg from module_free, rename module_memfree(). · be1f221c
      Rusty Russell authored
      
      
      Nothing needs the module pointer any more, and the next patch will
      call it from RCU, where the module itself might no longer exist.
      Removing the arg is the safest approach.
      
      This just codifies the use of the module_alloc/module_free pattern
      which ftrace and bpf use.

      module_arch_freeing_init(): new hook for archs before module->module_init freed. · d453cded
      Rusty Russell authored
      
      
      Archs have been abusing module_free() to clean up their arch-specific
      allocations.  Since module_free() is also (ab)used by BPF and trace code,
      let's keep it to simple allocations, and provide a hook called before
      that.
      
      This means that avr32, ia64, parisc and s390 no longer need to implement
      their own module_free() at all.  avr32 doesn't need module_finalize()
      either.

      I changed the "sprintf(sp->name, "%s Neterion %s"" to snprintf(), as
      well, even though it can't overflow just to be consistent.
