      ====================
      sparc64: Recover from userspace non-resumable PIO & MEM errors
      
      A non-resumable error from userspace is able to cause a kernel panic or trap
      loop due to the setup and handling of the queued traps once in the kernel.
      This patch series addresses both of these issues.
      
      The queues are fixed by simply zeroing the memory before use.
      
      PIO errors from userspace will result in a SIGBUS being sent to the user
      process.
      
      The MEM errors form userspace will result in a SIGKILL and also cause the
      offending pages to be claimed so they are no longer used in future tasks.
      SIGKILL is used to ensure that the process does not try to coredump and result
      in an attempt to read the memory again from within kernel space.  Although
      there is a HV call to scrub the memory (mem_scrub), there is no easy way to
      guarantee that the real memory address(es) are not used by other tasks.
      Clearing the error with mem_scrub would zero the memory and cause the other
      processes to proceed with bad data.
      
      The handling of other non-resumable errors remain unchanged and will cause a
      panic.

      Liam R. Howlett authored
      User processes trying to access an invalid memory address via PIO will
      receive a SIGBUS signal instead of causing a panic.  Memory errors will
      receive a SIGKILL since a SIGBUS may result in a coredump which may
      attempt to repeat the faulting access.

      sparc64: Zero pages on allocation for mondo and error queues. · 7a7dc961
      Liam R. Howlett authored
      Error queues use a non-zero first word to detect if the queues are full.
      Using pages that have not been zeroed may result in false positive
      overflow events.  These queues are set up once during boot so zeroing
      all mondo and error queue pages is safe.
      
      Note that the false positive overflow does not always occur because the
      page allocation for these queues is so early in the boot cycle that
      higher number CPUs get fresh pages.  It is only when traps are serviced
      with lower number CPUs who were given already used pages that this issue
      is exposed.

      drm/i915: Check for NULL i915_vma in intel_unpin_fb_obj() · 39cb2c9a
      Linus Torvalds authored
      I've seen this trigger twice now, where the i915_gem_object_to_ggtt()
      call in intel_unpin_fb_obj() returns NULL, resulting in an oops
      immediately afterwards as the (inlined) call to i915_vma_unpin_fence()
      tries to dereference it.
      
      It seems to be some race condition where the object is going away at
      shutdown time, since both times happened when shutting down the X
      server.  The call chains were different:
      
       - VT ioctl(KDSETMODE, KD_TEXT):
      
          intel_cleanup_plane_fb+0x5b/0xa0 [i915]
          drm_atomic_helper_cleanup_planes+0x6f/0x90 [drm_kms_helper]

          intel_atomic_commit+0x3cb/0x4f0 [i915]
          drm_atomic_commit+0x4b/0x50 [drm]
          restore_fbdev_mode+0x14c/0x2a0 [drm_kms_helper]
          drm_fb_helper_restore_fbdev_mode_unlocked+0x34/0x80 [drm_kms_helper]
          drm_fb_helper_set_par+0x2d/0x60 [drm_kms_helper]
          intel_fbdev_set_par+0x18/0x70 [i915]
          fb_set_var+0x236/0x460
          fbcon_blank+0x30f/0x350
          do_unblank_screen+0xd2/0x1a0
          vt_ioctl+0x507/0x12a0
          tty_ioctl+0x355/0xc30
          do_vfs_ioctl+0xa3/0x5e0
          SyS_ioctl+0x79/0x90
          entry_SYSCALL_64_fastpath+0x13/0x94
      
       - i915 unpin_work workqueue:
      
          intel_unpin_work_fn+0x58/0x140 [i915]
          process_one_work+0x1f1/0x480
          worker_thread+0x48/0x4d0
          kthread+0x101/0x140
      
      and this patch purely papers over the issue by adding a NULL pointer
      check and a WARN_ON_ONCE() to avoid the oops that would then generally
      make the machine unresponsive.
      
      Other callers of i915_gem_object_to_ggtt() seem to also check for the
      returned pointer being NULL and warn about it, so this clearly has
      happened before in other places.
      
      [ Reported it originally to the i915 developers on Jan 8, applying the
        ugly workaround on my own now after triggering the problem for the
        second time with no feedback.
      
        This is likely to be the same bug reported as
      
           https://bugs.freedesktop.org/show_bug.cgi?id=98829
           https://bugs.freedesktop.org/show_bug.cgi?id=99134
      
        which has a patch for the underlying problem, but it hasn't gotten to
        me, so I'm applying the workaround. ]

      parisc: Don't use BITS_PER_LONG in userspace-exported swab.h header · 2ad5d52d
      Helge Deller authored
      In swab.h the "#if BITS_PER_LONG > 32" breaks compiling userspace programs if
      BITS_PER_LONG is #defined by userspace with the sizeof() compiler builtin.
      
      Solve this problem by using __BITS_PER_LONG instead.  Since we now
      #include asm/bitsperlong.h avoid further potential userspace pollution
      by moving the #define of SHIFT_PER_LONG to bitops.h which is not
      exported to userspace.
      
      This patch unbreaks compiling qemu on hppa/parisc.

      percpu-refcount: fix reference leak during percpu-atomic transition · 966d2b04
      Douglas Miller authored
      percpu_ref_tryget() and percpu_ref_tryget_live() should return
      "true" IFF they acquire a reference. But the return value from
      atomic_long_inc_not_zero() is a long and may have high bits set,
      e.g. PERCPU_COUNT_BIAS, and the return value of the tryget routines
      is bool so the reference may actually be acquired but the routines
      return "false" which results in a reference leak since the caller
      assumes it does not need to do a corresponding percpu_ref_put().
      
      This was seen when performing CPU hotplug during I/O, as hangs in
      blk_mq_freeze_queue_wait where percpu_ref_kill (blk_mq_freeze_queue_start)
      raced with percpu_ref_tryget (blk_mq_timeout_work).
      Sample stack trace:

      SyS_write+0x6c/0x110
      system_call+0x38/0xe0
      
      Examination of the queue showed a single reference (no PERCPU_COUNT_BIAS,
      and __PERCPU_REF_DEAD, __PERCPU_REF_ATOMIC set) and no requests.
      However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0
      and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set.
      
      The fix is to make the tryget routines use an actual boolean internally instead
      of the atomic long result truncated to a int.

      RDMA/cma: Fix unknown symbol when CONFIG_IPV6 is not enabled · b4cfe397
      Jack Morgenstein authored
      If IPV6 has not been enabled in the underlying kernel, we must avoid
      calling IPV6 procedures in rdma_cm.ko.
      
      This requires using "IS_ENABLED(CONFIG_IPV6)" in "if" statements
      surrounding any code which calls external IPV6 procedures.
      
      In the instance fixed here, procedure cma_bind_addr() called
      ipv6_addr_type() -- which resulted in calling external procedure
      __ipv6_addr_type().

      ARC: [arcompact] handle unaligned access delay slot corner case · 9aed02fe
      Vineet Gupta authored
      After emulating an unaligned access in delay slot of a branch, we
      pretend as the delay slot never happened - so return back to actual
      branch target (or next PC if branch was not taken).
      
      Curently we did this by handling STATUS32.DE, we also need to clear the
      BTA.T bit, which is disregarded when returning from original misaligned
      exception, but could cause weirdness if it took the interrupt return
      path (in case interrupt was acive too)
      
      One ARC700 customer ran into this when enabling unaligned access fixup
      for kernel mode accesses as well

      xfs: prevent quotacheck from overloading inode lru · e0d76fa4
      Brian Foster authored
      Quotacheck runs at mount time in situations where quota accounting must
      be recalculated. In doing so, it uses bulkstat to visit every inode in
      the filesystem. Historically, every inode processed during quotacheck
      was released and immediately tagged for reclaim because quotacheck runs
      before the superblock is marked active by the VFS. In other words,
      the final iput() lead to an immediate ->destroy_inode() call, which
      allowed the XFS background reclaim worker to start reclaiming inodes.
      
      Commit 17c12bcd ("xfs: when replaying bmap operations, don't let
      unlinked inodes get reaped") marks the XFS superblock active sooner as
      part of the mount process to support caching inodes processed during log
      recovery. This occurs before quotacheck and thus means all inodes
      processed by quotacheck are inserted to the LRU on release.  The
      s_umount lock is held until the mount has completed and thus prevents
      the shrinkers from operating on the sb. This means that quotacheck can
      excessively populate the inode LRU and lead to OOM conditions on systems
      without sufficient RAM.
      
      Update the quotacheck bulkstat handler to set XFS_IGET_DONTCACHE on
      inodes processed by quotacheck. This causes ->drop_inode() to return 1
      and in turn causes iput_final() to evict the inode. This preserves the
      original quotacheck behavior and prevents it from overloading the LRU
      and running out of memory.
