      Pull a percpu fix from Tejun Heo:
       "Fix for a percpu allocator bug where it could try to kfree() a memory
        region allocated using vmalloc().  The bug has been there for years
        now and is unlikely to have ever triggered given the size of struct
        pcpu_chunk.  It's still theoretically possible and the fix is simple
        and safe enough, so the patch is marked with -stable"

      Pull ARM SoC fixes from Olof Johansson:
       "Seems like we've had more fixes than usual this release cycle, but
        there's nothing in particular that we're doing differently.  Perhaps
        it's just one of those cycles where more people are finding more
        regressions (and/or that the latency of when people actually test
        what's been in the tree for a while is catching up so that we get the
        bug reports now).
      
        The bigger changes here are are for TI and Marvell platforms:
         * Timing changes for GPMC (generic localbus) on OMAP causing some
           largeish DTS deltas.
         * Fixes to window allocation on PCI for mvebu touching drivers/
           stuff.  Patches have acks from subsystem maintainers where needed.
         * A fix from Thomas for a botched DT conversion in drivers/edma.
      
        There's a handful of other fixes for the above platforms as well as
        sunxi, at91, i.MX.  I also included a MAINTAINER update for Broadcom,
        and a trivial move of a binding doc.

        it for when you return.  :)"

      Pull tracing fixes from Steven Rostedt:
       "This contains two fixes.
      
        The first is a long standing bug that causes bogus data to show up in
        the refcnt field of the module_refcnt tracepoint.  It was introduced
        by a merge conflict resolution back in 2.6.35-rc days.
      
        The result should be 'refcnt = incs - decs', but instead it did
        'refcnt = incs + decs'.
      
        The second fix is to a bug that was introduced in this merge window
        that allowed for a tracepoint funcs pointer to be used after it was
        freed.  Moving the location of where the probes are released solved
        the problem"

      NFSD: Call ->set_acl with a NULL ACL structure if no entries · aa07c713
      Kinglong Mee authored
      After setting ACL for directory, I got two problems that caused
      by the cached zero-length default posix acl.
      
      This patch make sure nfsd4_set_nfs4_acl calls ->set_acl
      with a NULL ACL structure if there are no entries.
      
      Thanks for Christoph Hellwig's advice.

      tracepoint: Fix use of tracepoint funcs after rcu free · 8058bd0f
      Mathieu Desnoyers authored
      Commit de7b2973 "tracepoint: Use struct pointer instead of name hash
      for reg/unreg tracepoints" introduces a use after free by calling
      release_probes on the old struct tracepoint array before the newly
      allocated array is published with rcu_assign_pointer. There is a race
      window where tracepoints (RCU readers) can perform a
      "use-after-grace-period-after-free", which shows up as a GPF in
      stress-tests.

      trace: module: Maintain a valid user count · 098507ae
      Romain Izard authored
      The replacement of the 'count' variable by two variables 'incs' and
      'decs' to resolve some race conditions during module unloading was done
      in parallel with some cleanup in the trace subsystem, and was integrated
      as a merge.
      
      Unfortunately, the formula for this replacement was wrong in the tracing
      code, and the refcount in the traces was not usable as a result.
      
      Use 'count = incs - decs' to compute the user count.

      mmc: rtsx: Revert "mmc: rtsx: add support for pre_req and post_req" · 98fcc576
      Micky Ching authored
      This reverts commit c42deffd.
      
      commit <mmc: rtsx: add support for pre_req and post_req> did use
      mutex_unlock() in tasklet, but mutex_unlock() can't be used in
      tasklet(atomic context). The driver needs to use mutex to avoid
      concurrency, so we can't use tasklet here, the patch need to be
      removed.
      
      The spinlock host->lock and pcr->lock may deadlock, one way to solve
      the deadlock is remove host->lock in sd_isr_done_transfer(), but if
      using workqueue the we can avoid using the spinlock and also avoid
      the problem.

      HPET on some platform has accuracy problem. Making
      "boot_hpet_disable" extern so that we can runtime disable

      x86-64, build: Fix stack protector Makefile breakage with 32-bit userland · 14262d67
      George Spelvin authored
      If you are using a 64-bit kernel with 32-bit userland, then
      scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc
      with -mcmodel=kernel, which produces:
      
      <stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode
      
      and trips the "broken compiler" test at arch/x86/Makefile:120.
      
      There are several places a fix is possible, but the following seems
      cleanest.  (But it's minimal; it would also be possible to factor
      out a bunch of stuff from the two branches of the if.)
