      CRISv32: ETRAXFS: Fix recursive spinlock · a3199ad9
      Jesper Nilsson authored
      Move pinmux alloc/dealloc code into functions that don't take
      the spinlock so we can use from code that has the spinlock already.
      
      CRISv32 has no working SMP, so spinlocks becomes a NOP,
      so deadlock was never seen.

      CRIS: Export missing function symbols · dbd3c7e1
      Jesper Nilsson authored
      strcmp was lost when all other string functions were removed,
      but we still have an optimized version for this on CRISv32,
      so any driver built as a module would not have access to this symbol.
      
      In a similar manner, we had optimized versions of
      csum_partial_copy_from_user and __do_clear_user
      but no exported symbols for them, breaking bunch of other drivers
      when built as a module.
      
      At the same time, move EXPORT_SYMBOL(__copy_user) and
      EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
      located together with the function definition.

      Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · e589c9e1
      Linus Torvalds authored
      Pull x86 apic updates from Thomas Gleixner:
       "After stopping the full x86/apic branch, I took some time to go
        through the first block of patches again, which are mostly cleanups
        and preparatory work for the irqdomain conversion and ioapic hotplug
        support.
      
        Unfortunaly one of the real problematic commits was right at the
        beginning, so I rebased this portion of the pending patches without
        the offenders.
      
        It would be great to get this into 3.19.  That makes reworking the
        problematic parts simpler.  The usual tip testing did not unearth any
        issues and it is fully bisectible now.
      
        I'm pretty confident that this wont affect the calmness of the xmas
        season.
      
        Changes:
         - Split the convoluted io_apic.c code into domain specific parts
           (vector, ioapic, msi, htirq)
         - Introduce proper helper functions to retrieve irq specific data
           instead of open coded dereferencing of pointers
         - Preparatory work for ioapic hotplug and irqdomain conversion
         - Removal of the non functional pci-ioapic driver
         - Removal of unused irq entry stubs
         - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
           allocations for everything which is called from there.
         - Small cleanups and fixes"

      tick/powerclamp: Remove tick_nohz_idle abuse · a5fd9733
      Thomas Gleixner authored
      commit 4dbd2771 "tick: export nohz tick idle symbols for module
      use" was merged via the thermal tree without an explicit ack from the
      relevant maintainers.
      
      The exports are abused by the intel powerclamp driver which implements
      a fake idle state from a sched FIFO task. This causes all kinds of
      wreckage in the NOHZ core code which rightfully assumes that
      tick_nohz_idle_enter/exit() are only called from the idle task itself.
      
      Recent changes in the NOHZ core lead to a failure of the powerclamp
      driver and now people try to hack completely broken and backwards
      workarounds into the NOHZ core code. This is completely unacceptable
      and just papers over the real problem. There are way more subtle
      issues lurking around the corner.
      
      The real solution is to fix the powerclamp driver by rewriting it with
      a sane concept, but that's beyond the scope of this.
      
      So the only solution for now is to remove the calls into the core NOHZ
      code from the powerclamp trainwreck along with the exports.

      Wang Nan authored
      Commit 85c116a6 ("perf callchain: Make get_srcline fall back to sym+offset")
      introduces asprintf() call and matches '%ld' to a u64 argument, which is

      In addition, all users of get_srcline() use u64 addr, and libbfd
      also use 64 bit bfd_vma as address. This patch also fix
      prototype of get_srcline() and addr2line() to use u64 addr

      Pull more ACPI and power management updates from Rafael Wysocki:
       "These are regression fixes (leds-gpio, ACPI backlight driver,
        operating performance points library, ACPI device enumeration
        messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device
        PM), some cleanups in the operating performance points (OPP)
        framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of
        minor intel_pstate driver changes, a new MAINTAINERS entry for it and
        an ACPI fan driver change needed for better support of thermal
        management in user space.
      
        Specifics:
      
         - Fix a regression in leds-gpio introduced by a recent commit that
           inadvertently changed the name of one of the properties used by the
           driver (Fabio Estevam).
      
         - Fix a regression in the ACPI backlight driver introduced by a
           recent fix that missed one special case that had to be taken into
           account (Aaron Lu).
      
         - Drop the level of some new kernel messages from the ACPI core
           introduced by a recent commit to KERN_DEBUG which they should have
           used from the start and drop some other unuseful KERN_ERR messages
           printed by ACPI (Rafael J Wysocki).
      
         - Revert an incorrect commit modifying the cpupower tool (Prarit
           Bhargava).
      
         - Fix two regressions introduced by recent commits in the OPP library
           and clean up some existing minor issues in that code (Viresh
           Kumar).
      
         - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
           tree (or drop it where that can be done) in order to make it
           possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
           Hansson, Ludovic Desroches).
      
           There will be one more "CONFIG_PM_RUNTIME removal" batch after this
           one, because some new uses of it have been introduced during the
           current merge window, but that should be sufficient to finally get
           rid of it.
      
         - Make the ACPI EC driver more robust against race conditions related
           to GPE handler installation failures (Lv Zheng).
      
         - Prevent the ACPI device PM core code from attempting to disable
           GPEs that it has not enabled which confuses ACPICA and makes it
           report errors unnecessarily (Rafael J Wysocki).
      
         - Add a "force" command line switch to the intel_pstate driver to
           make it possible to override the blacklisting of some systems in
           that driver if needed (Ethan Zhao).
      
         - Improve intel_pstate code documentation and add a MAINTAINERS entry
           for it (Kristen Carlson Accardi).
      
         - Make the ACPI fan driver create cooling device interfaces witn
           names that reflect the IDs of the ACPI device objects they are
           associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").
      
           That's necessary for user space thermal management tools to be able
           to connect the fans with the parts of the system they are supposed
           to be cooling properly.  From Srinivas Pandruvada"

      mm/zsmalloc: adjust order of functions · 66cdef66
      Ganesh Mahendran authored
      Currently functions in zsmalloc.c does not arranged in a readable and
      reasonable sequence.  With the more and more functions added, we may
      meet below inconvenience.  For example:
      
      Current functions:
      
          void zs_init()
          {
          }
      
          static void get_maxobj_per_zspage()
          {
          }
      
      Then I want to add a func_1() which is called from zs_init(), and this
      new added function func_1() will used get_maxobj_per_zspage() which is
      defined below zs_init().
      
          void func_1()
          {
              get_maxobj_per_zspage()
          }
      
          void zs_init()
          {
              func_1()
          }
      
          static void get_maxobj_per_zspage()
          {
          }
      
      This will cause compiling issue. So we must add a declaration:
      
          static void get_maxobj_per_zspage();
      
      before func_1() if we do not put get_maxobj_per_zspage() before
      func_1().
      
      In addition, puting module_[init|exit] functions at the bottom of the
      file conforms to our habit.
      
      So, this patch ajusts function sequence as:
      
          /* helper functions */
          ...
          obj_location_to_handle()
          ...
      
          /* Some exported functions */
          ...
      
          zs_map_object()
          zs_unmap_object()
      
          zs_malloc()
          zs_free()
      
          zs_init()
          zs_exit()

      ocfs2: fix journal commit deadlock · 136f49b9
      Junxiao Bi authored
      For buffer write, page lock will be got in write_begin and released in
      write_end, in ocfs2_write_end_nolock(), before it unlock the page in
      ocfs2_free_write_ctxt(), it calls ocfs2_run_deallocs(), this will ask
      for the read lock of journal->j_trans_barrier.  Holding page lock and
      ask for journal->j_trans_barrier breaks the locking order.
      
      This will cause a deadlock with journal commit threads, ocfs2cmt will
      get write lock of journal->j_trans_barrier first, then it wakes up
      kjournald2 to do the commit work, at last it waits until done.  To
      commit journal, kjournald2 needs flushing data first, it needs get the
      cache page lock.
      
      Since some ocfs2 cluster locks are holding by write process, this
      deadlock may hung the whole cluster.
      
      unlock pages before ocfs2_run_deallocs() can fix the locking order, also
      put unlock before ocfs2_commit_trans() to make page lock is unlocked
      before j_trans_barrier to preserve unlocking order.

      The slow unlink is caused by the contention of refcount tree lock since
      all nodes are unlink files using the same refcount tree.  When the
      unlinking file have many extents(over 1600 in our test), most of the
      extents has refcounted flag set.  In ocfs2_commit_truncate(), it will
      execute the following call trace for every extents.  This means it needs
      get and released refcount tree lock about 1600 times.  And when several
      nodes are do this at the same time, the performance will be very low.
      
        ocfs2_remove_btree_range()
        --  ocfs2_lock_refcount_tree()
        ----  ocfs2_refcount_lock()
        ------  __ocfs2_cluster_lock()
      
      ocfs2_refcount_lock() is costly, move it to ocfs2_commit_truncate() to
      do lock/unlock once can improve a lot performance.
