      mips: Remove compiler check in unroll macro · 9321f1aa
      Nathan Chancellor authored
      CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build
      (see our Travis link below).
      
      Clang 8 was chosen as a minimum version for this check because there
      were some improvements around __builtin_constant_p in that release. In
      reality, MIPS was not even buildable until clang 9 so that check was not
      technically necessary. Just remove all compiler checks and just assume
      that we have a working compiler.
      
      Fixes: d4e60453 ("Restore gcc check in mips asm/unroll.h")

      mlxsw: pci: Fix use-after-free in case of failed devlink reload · c4317b11
      Ido Schimmel authored
      In case devlink reload failed, it is possible to trigger a
      use-after-free when querying the kernel for device info via 'devlink dev
      info' [1].
      
      This happens because as part of the reload error path the PCI command
      interface is de-initialized and its mailboxes are freed. When the
      devlink '->info_get()' callback is invoked the device is queried via the
      command interface and the freed mailboxes are accessed.
      
      Fix this by initializing the command interface once during probe and not
      during every reload.
      
      This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c')
      and also allows user space to query the running firmware version (for
      example) from the device after a failed reload.

      ====================
      net: macb: Wake-on-Lan magic packet fixes and GEM handling
      
      Here is a split series to fix WoL magic-packet on the current macb driver. Only
      fixes in this one based on current net/master.
      
      Changes in v5:
      - Addressed the error code returned by phylink_ethtool_set_wol() as suggested
        by Russell.
        If PHY handles WoL, MAC doesn't stay in the way.
      - Removed Florian's tag on 3/5 because of the above changes.
      - Correct the "Fixes" tag on 1/5.
      
      Changes in v4:
      - Pure bug fix series for 'net'. GEM addition and MACB update removed: will be
        sent later.
      
      Changes in v3:
      - Revert some of the v2 changes done in macb_resume(). Now the resume function
        supports in-depth re-configuration of the controller in order to deal with
        deeper sleep states. Basically as it was before changes introduced by this
        series
      - Tested for non-regression with our deeper Power Management mode which cuts
        power to the controller completely
      
      Changes in v2:
      - Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()")
        needed for keeping phy state consistent
      - Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent
        putting the macb in runtime pm suspend mode when WoL is used
      - Collect review tags on 3 first patches from Florian: Thanks!
      - Review of macb_resume() function
      - Addition of pm_wakeup_event() in both MACB and GEM WoL IRQ handlers

      Nicolas Ferre authored
      Keep previous function goals and integrate phylink actions to them.
      
      phylink_ethtool_get_wol() is not enough to figure out if Ethernet driver
      supports Wake-on-Lan.
      Initialization of "supported" and "wolopts" members is done in phylink
      function, no need to keep them in calling function.
      
      phylink_ethtool_set_wol() return value is considered and determines
      if the MAC has to handle WoL or not. The case where the PHY doesn't
      implement WoL leads to the MAC configuring it to provide this feature.

      net: macb: mark device wake capable when "magic-packet" property present · ced4799d
      Nicolas Ferre authored
      Change the way the "magic-packet" DT property is handled in the
      macb_probe() function, matching DT binding documentation.
      Now we mark the device as "wakeup capable" instead of calling the
      device_init_wakeup() function that would enable the wakeup source.
      
      For Ethernet WoL, enabling the wakeup_source is done by
      using ethtool and associated macb_set_wol() function that
      already calls device_set_wakeup_enable() for this purpose.
      
      That would reduce power consumption by cutting more clocks if
      "magic-packet" property is set but WoL is not configured by ethtool.

      net: macb: fix wakeup test in runtime suspend/resume routines · 515a10a7
      Nicolas Ferre authored
      Use the proper struct device pointer to check if the wakeup flag
      and wakeup source are positioned.
      Use the one passed by function call which is equivalent to
      &bp->dev->dev.parent.
      
      It's preventing the trigger of a spurious interrupt in case the
      Wake-on-Lan feature is used.

      bnxt_en: fix NULL dereference in case SR-IOV configuration fails · c8b1d743
      Davide Caratti authored
      we need to set 'active_vfs' back to 0, if something goes wrong during the
      allocation of SR-IOV resources: otherwise, further VF configurations will
      wrongly assume that bp->pf.vf[x] are valid memory locations, and commands
      like the ones in the following sequence:
      
       # echo 2 >/sys/bus/pci/devices/${ADDR}/sriov_numvfs
       # ip link set dev ens1f0np0 up
       # ip link set dev ens1f0np0 vf 0 trust on
      
      will cause a kernel crash similar to this:
      
       bnxt_en 0000:3b:00.0: not enough MMIO resources for SR-IOV
