        pull requests.
      
        This contains fixes for a few ARM platforms (msm, tilcdc, meson), and
        one core atomic fix. The AMD pull has some new hardware support
        (Polaris12) in it, but this is pretty limited to just hw enablement
        and shouldn't cause any problems"

      We make the bcm_sf2 driver override ds->ops which points to

      well and good until a second b53 switch comes in, and ends up using the
      bcm_sf2 operations. Make a proper local copy, substitute the ds->ops
      pointer and then override the operations.

      Michael Chan authored
      The driver's ndo_get_stats64() method is not always called under RTNL.
      So it can race with driver close or ethtool reconfigurations.  Fix the
      race condition by taking tp->lock spinlock in tg3_free_consistent()
      when freeing the tp->hw_stats memory block.  tg3_get_stats64() is
      already taking tp->lock.

      mm: workingset: fix use-after-free in shadow node shrinker · ea07b862
      Johannes Weiner authored
      Several people report seeing warnings about inconsistent radix tree
      nodes followed by crashes in the workingset code, which all looked like
      use-after-free access from the shadow node shrinker.
      
      Dave Jones managed to reproduce the issue with a debug patch applied,
      which confirmed that the radix tree shrinking indeed frees shadow nodes
      while they are still linked to the shadow LRU:
      
        WARNING: CPU: 2 PID: 53 at lib/radix-tree.c:643 delete_node+0x1e4/0x200
        CPU: 2 PID: 53 Comm: kswapd0 Not tainted 4.10.0-rc2-think+ #3
        Call Trace:
           delete_node+0x1e4/0x200
           __radix_tree_delete_node+0xd/0x10
           shadow_lru_isolate+0xe6/0x220
           __list_lru_walk_one.isra.4+0x9b/0x190
           list_lru_walk_one+0x23/0x30
           scan_shadow_nodes+0x2e/0x40
           shrink_slab.part.44+0x23d/0x5d0
           shrink_node+0x22c/0x330
           kswapd+0x392/0x8f0
      
      This is the WARN_ON_ONCE(!list_empty(&node->private_list)) placed in the
      inlined radix_tree_shrink().
      
      The problem is with 14b46879 ("mm: workingset: move shadow entry
      tracking to radix tree exceptional tracking"), which passes an update
      callback into the radix tree to link and unlink shadow leaf nodes when
      tree entries change, but forgot to pass the callback when reclaiming a
      shadow node.
      
      While the reclaimed shadow node itself is unlinked by the shrinker, its
      deletion from the tree can cause the left-most leaf node in the tree to
      be shrunk.  If that happens to be a shadow node as well, we don't unlink
      it from the LRU as we should.
      
      Consider this tree, where the s are shadow entries:
      
             root->rnode
                  |
             [0       n]
              |       |
           [s    ] [sssss]
      
      Now the shadow node shrinker reclaims the rightmost leaf node through
      the shadow node LRU:
      
             root->rnode
                  |
             [0        ]
              |
          [s     ]
      
      Because the parent of the deleted node is the first level below the
      root and has only one child in the left-most slot, the intermediate
      level is shrunk and the node containing the single shadow is put in
      its place:
      
             root->rnode
                  |
             [s        ]
      
      The shrinker again sees a single left-most slot in a first level node
      and thus decides to store the shadow in root->rnode directly and free
      the node - which is a leaf node on the shadow node LRU.
      
        root->rnode
             |
             s
      
      Without the update callback, the freed node remains on the shadow LRU,
      where it causes later shrinker runs to crash.
      
      Pass the node updater callback into __radix_tree_delete_node() in case
      the deletion causes the left-most branch in the tree to collapse too.
      
      Also add warnings when linked nodes are freed right away, rather than
      wait for the use-after-free when the list is scanned much later.

      mm: stop leaking PageTables · b0b9b3df
      Hugh Dickins authored
      4.10-rc loadtest (even on x86, and even without THPCache) fails with
      "fork: Cannot allocate memory" or some such; and /proc/meminfo shows
      PageTables growing.
      
      Commit 953c66c2 ("mm: THP page cache support for ppc64") that got
      merged in rc1 removed the freeing of an unused preallocated pagetable
      after do_fault_around() has called map_pages().
      
      This is usually a good optimization, so that the followup doesn't have
      to reallocate one; but it's not sufficient to shift the freeing into
      alloc_set_pte(), since there are failure cases (most commonly
      VM_FAULT_RETRY) which never reach finish_fault().
      
      Check and free it at the outer level in do_fault(), then we don't need
      to worry in alloc_set_pte(), and can restore that to how it was (I
      cannot find any reason to pte_free() under lock as it was doing).
      
      And fix a separate pagetable leak, or crash, introduced by the same
      change, that could only show up on some ppc64: why does do_set_pmd()'s
      failure case attempt to withdraw a pagetable when it never deposited
      one, at the same time overwriting (so leaking) the vmf->prealloc_pte?
      Residue of an earlier implementation, perhaps? Delete it.
