      Reason for this problem is that commit 031bc574
      ("mm/debug-pagealloc: make debug-pagealloc boottime configurable")
      forgot to remove the old declaration of kernel_map_pages() for some
      architectures.  This patch removes them to fix build failure.

      nilfs2: fix deadlock of segment constructor over I_SYNC flag · 7ef3ff2f
      Ryusuke Konishi authored
      Nilfs2 eventually hangs in a stress test with fsstress program.  This
      issue was caused by the following deadlock over I_SYNC flag between
      nilfs_segctor_thread() and writeback_sb_inodes():
      
        nilfs_segctor_thread()
          nilfs_segctor_thread_construct()
            nilfs_segctor_unlock()
              nilfs_dispose_list()
                iput()
                  iput_final()
                    evict()
                      inode_wait_for_writeback()  * wait for I_SYNC flag
      
        writeback_sb_inodes()
           * set I_SYNC flag on inode->i_state
          __writeback_single_inode()
            do_writepages()
              nilfs_writepages()
                nilfs_construct_dsync_segment()
                  nilfs_segctor_sync()
                     * wait for completion of segment constructor
          inode_sync_complete()
             * clear I_SYNC flag after __writeback_single_inode() completed
      
      writeback_sb_inodes() calls do_writepages() for dirty inodes after
      setting I_SYNC flag on inode->i_state.  do_writepages() in turn calls
      nilfs_writepages(), which can run segment constructor and wait for its
      completion.  On the other hand, segment constructor calls iput(), which
      can call evict() and wait for the I_SYNC flag on
      inode_wait_for_writeback().
      
      Since segment constructor doesn't know when I_SYNC will be set, it
      cannot know whether iput() will block or not unless inode->i_nlink has a
      non-zero count.  We can prevent evict() from being called in iput() by
      implementing sop->drop_inode(), but it's not preferable to leave inodes
      with i_nlink == 0 for long periods because it even defers file
      truncation and inode deallocation.  So, this instead resolves the
      deadlock by calling iput() asynchronously with a workqueue for inodes
      with i_nlink == 0.

      memcg, shmem: fix shmem migration to use lrucare · f5e03a49
      Michal Hocko authored
      It has been reported that 965GM might trigger
      
        VM_BUG_ON_PAGE(!lrucare && PageLRU(oldpage), oldpage)
      
      in mem_cgroup_migrate when shmem wants to replace a swap cache page
      because of shmem_should_replace_page (the page is allocated from an
      inappropriate zone).  shmem_replace_page expects that the oldpage is not
      on LRU list and calls mem_cgroup_migrate without lrucare.  This is
      obviously incorrect because swapcache pages might be on the LRU list
      (e.g. swapin readahead page).
      
      Fix this by enabling lrucare for the migration in shmem_replace_page.
      Also clarify that lrucare should be used even if one of the pages might
      be on LRU list.
      
      The BUG_ON will trigger only when CONFIG_DEBUG_VM is enabled but even
      without that the migration code might leave the old page on an
      inappropriate memcg' LRU which is not that critical because the page
      would get removed with its last reference but it is still confusing.

      mm: export "high_memory" symbol on !MMU · 944b6874
      Arnd Bergmann authored
      The symbol 'high_memory' is provided on both MMU- and NOMMU-kernels, but
      only one of them is exported, which leads to module build errors in
      drivers that work fine built-in:
      
        ERROR: "high_memory" [drivers/net/virtio_net.ko] undefined!

      This exports the symbol to get these to work on NOMMU as well.

      mm: pagewalk: call pte_hole() for VM_PFNMAP during walk_page_range · 23aaed66
      Shiraz Hashim authored
      walk_page_range() silently skips vma having VM_PFNMAP set, which leads
      to undesirable behaviour at client end (who called walk_page_range).
      Userspace applications get the wrong data, so the effect is like just
      confusing users (if the applications just display the data) or sometimes
      killing the processes (if the applications do something with
      misunderstanding virtual addresses due to the wrong data.)
      
      For example for pagemap_read, when no callbacks are called against
      VM_PFNMAP vma, pagemap_read may prepare pagemap data for next virtual
      address range at wrong index.
      
      Eventually userspace may get wrong pagemap data for a task.
      Corresponding to a VM_PFNMAP marked vma region, kernel may report
      mappings from subsequent vma regions.  User space in turn may account
      more pages (than really are) to the task.
      
      In my case I was using procmem, procrack (Android utility) which uses
      pagemap interface to account RSS pages of a task.  Due to this bug it
      was giving a wrong picture for vmas (with VM_PFNMAP set).

      ASoC: Fixes for v3.19
      
      A few last minute fixes for v3.19, all driver specific.  None of them
      stand out particularly - it's all the standard people who are affected
      will care stuff.
      
      The Samsung fix is a DT only fix for the audio controller, it's being
      merged via the ASoC tree due to process messups (the submitter sent it
      at the end of a tangentally related series rather than separately to the
      ARM folks) in order to make sure that it gets to people sooner.

      IRQCHIP: mips-gic: Avoid rerouting timer IRQs for smp-cmp · 1b6af71a
      James Hogan authored
      Commit e9de688d ("irqchip: mips-gic: Support local interrupts")
      changed the GIC irqchip driver so that all local interrupts were routed
      to the same CPU pin used for external interrupts. Unfortunately this
      causes a regression when smp-cmp is used. The CPUs are started by the
      bootloader and put in a timer based waiting poll loop, but when their
      timer interrupts are rerouted to a different IRQ pin which is not
      unmasked they never wake up.
      
      Since smp-cmp support is deprecated and everybody who was using it
      should be switching to smp-cps which brings up the secondary CPUs
      without bootloader assistance, I've gone for the simple fix which can be
      easily removed once smp-cmp is removed, rather than a fully generic fix.
      
      In __gic_init() the local GIC_VPE_TIMER_MAP register is read to find the
      boot-time routing of the local timer interrupt, and a chained handler is
      added to that CPU pin as well as the normal one.

      hrtimer: Fix incorrect tai offset calculation for non high-res timer systems · 2d926c15
      John Stultz authored
      I noticed some CLOCK_TAI timer test failures on one of my
      less-frequently used configurations. And after digging in I
      found in 76f41088 (Cleanup hrtimer accessors to the
      timekepeing state), the hrtimer_get_softirq_time tai offset
      calucation was incorrectly rewritten, as the tai offset we
      return shold be from CLOCK_MONOTONIC, and not CLOCK_REALTIME.
      
      This results in CLOCK_TAI timers expiring early on non-highres
      capable machines.
      
      This patch fixes the issue, calculating the tai time properly
      from the monotonic base.
