      bnx2x: Prevent load reordering in tx completion processing · ea811b79
      Brian King authored
      This patch fixes an issue seen on Power systems with bnx2x which results
      in the skb is NULL WARN_ON in bnx2x_free_tx_pkt firing due to the skb
      pointer getting loaded in bnx2x_free_tx_pkt prior to the hw_cons
      load in bnx2x_tx_int. Adding a read memory barrier resolves the issue.

      net: phy: sfp: hwmon: Fix scaling of RX power · 0cea0e11
      Andrew Lunn authored
      The RX power read from the SFP uses units of 0.1uW. This must be
      scaled to units of uW for HWMON. This requires a divide by 10, not the
      current 100.
      
      With this change in place, sensors(1) and ethtool -m agree:

      net: sched: verify that q!=NULL before setting q->flags · 503d81d4
      Vlad Buslov authored
      In function int tc_new_tfilter() q pointer can be NULL when adding filter
      on a shared block. With recent change that resets TCQ_F_CAN_BYPASS after
      filter creation, following NULL pointer dereference happens in case parent
      block is shared:

      We have a handful of fixes:
       * ignore bad CW parameters if we aren't using them,
         instead of warning
       * fix operation (and then build) with the new netlink vendor
         command policy requirement
       * fix a memory leak in an error path when setting beacons

       "Dave is back in shape, but now family got it so I'm doing the pull.
        Two things worthy of note:
      
         - nouveau feature pull was way too late, Dave&me decided to not take
           that, so Ben spun up a pull with just the fixes.
      
         - after some chatting with the arm display maintainers we decided to
           change a bit how that's maintained, for more oversight/review and
           cross vendor collab.
      
        More details below:

           Fix /proc/pid/smaps output for THP pages used in shmem.

           Bugfix and speedup for kernel/resource.c

           Hildenbrand.
      
           More spring-cleaning of the memory hotplug code.
      
         - Patch series "mm: Sub-section memory hotplug support". Dan
           Williams.
      
           Generalise the memory hotplug code so that pmem can use it more
           completely. Then remove the hacks from the libnvdimm code which
           were there to work around the memory-hotplug code's constraints.
      
         - "proc/sysctl: add shared variables for range check", Matteo Croce.

           "zero"s and "one"s use global variables.

      tracing: Fix user stack trace "??" output · 6d54ceb5
      Eiichi Tsukata authored
      Commit c5c27a0a ("x86/stacktrace: Remove the pointless ULONG_MAX
      marker") removes ULONG_MAX marker from user stack trace entries but
      trace_user_stack_print() still uses the marker and it outputs unnecessary
      "??".
      
      For example:
      
                  less-1911  [001] d..2    34.758944: <user stack trace>
         =>  <00007f16f2295910>
         => ??
         => ??
         => ??
         => ??
         => ??
         => ??
         => ??
      
      The user stack trace code zeroes the storage before saving the stack, so if
      the trace is shorter than the maximum number of entries it can terminate
      the print loop if a zero entry is detected.

      This can happen because the NF_TABLES_BRIDGE dependency itself is just a
      'bool'.  Make the symbol a 'tristate' instead so Kconfig can propagate the
      dependencies correctly.

      drm/nouveau: fix memory leak in nouveau_conn_reset() · 09b90e2f
      Yongxin Liu authored
      In nouveau_conn_reset(), if connector->state is true,
      __drm_atomic_helper_connector_destroy_state() will be called,
      but the memory pointed by asyc isn't freed. Memory leak happens
      in the following function __drm_atomic_helper_connector_reset(),
      where newly allocated asyc->state will be assigned to connector->state.
      
      So using nouveau_conn_atomic_destroy_state() instead of
      __drm_atomic_helper_connector_destroy_state to free the "old" asyc.
      
      Here the is the log showing memory leak.
