      cbq: incorrectly low bandwidth blocks limited traffic
      
      v2: patch description changes
      Fixes: f0f6ee1f ("cbq: incorrect processing of high limits")
      
      Mainstream commit f0f6ee1f ("cbq: incorrect processing of high limits")
      have side effect: if cbq bandwidth setting is less than real interface
      throughput non-limited traffic can delay limited traffic for a very long time.
      
      This happen because of q->now changes incorrectly in cbq_dequeue():
      in described scenario L2T is much greater than real time delay,
      and q->now gets an extra boost for each transmitted packet.
      
      Accumulated boost prevents update q->now, and blocked class can wait
      very long time until (q->now >= cl->undertime) will be true again.
      
      More detailed problem description can be found here:
      http://www.spinics.net/lists/netdev/msg292493.html
      
      
      
      Following patches should fix the problem.

      To fix the problem the patch updates q->now on each cbq_update() call.
      L2T-related pre-modification q->now was moved to cbq_update().
      
      My testing confirmed that it fixes the problem and did not discover
      any side-effects

      i40e: Fix a few potential VF dereferences · 6e7b5bd3
      Anjali Singhai Jain authored
      
      
      In some functions we might be doing potential dereference
      without a check. This patch puts the check in place for all these
      functions. Also fix the "for loops" so that we increment VF at the
      right place so that we always do it even if we are short-circuiting
      the loop through continue.

      i40e: Fix for recent kernel panic · 478c9e74
      Anjali Singhai Jain authored
      
      
      Whenever we get a Tx hang we issue a PFR, which means we send AQ
      messages to VFS about the reset coming. Unfortunately with the recent
      fix to be able to send messages to all VFS which earlier was not
      happening at all we now are sending messages to not just the VFS that
      are up but also to VFS that are not up.  AQ complains about this and
      sends us an error in ARQ called LAN overflow event for a queue. We
      check if the queue belongs to a VF and if it does we try to send a
      vc_notify_vf_reset message to that VF. Well if the VF is not up/enabled
      we will be entering this function with a non-active VF id. In this
      function we were assuming VF struct is populated but it won't be if
      the VF is not active.

      Pull more ACPI and power management updates from Rafael Wysocki:
       "These are a couple of regression fixes, cpuidle menu governor
        optimizations, fixes for ACPI proccessor and battery drivers,
        hibernation fix to avoid problems related to the e820 memory map,
        fixes for a few cpufreq drivers and a new version of the suspend
        profiling tool analyze_suspend.py.
      
        Specifics:
      
         - Fix for an ACPI-based device hotplug regression introduced in 3.14
           that causes a kernel panic to trigger when memory hot-remove is
           attempted with CONFIG_ACPI_HOTPLUG_MEMORY unset from Tang Chen
      
         - Fix for a cpufreq regression introduced in 3.16 that triggers a
           "sleeping function called from invalid context" bug in
           dev_pm_opp_init_cpufreq_table() from Stephen Boyd
      
         - ACPI battery driver fix for a warning message added in 3.16 that
           prints silly stuff sometimes from Mariusz Ceier
      
         - Hibernation fix for safer handling of mismatches in the 820 memory
           map between the configurations during image creation and during the
           subsequent restore from Chun-Yi Lee
      
         - ACPI processor driver fix to handle CPU hotplug notifications
           correctly during system suspend/resume from Lan Tianyu
      
         - Series of four cpuidle menu governor cleanups that also should
           speed it up a bit from Mel Gorman
      
         - Fixes for the speedstep-smi, integrator, cpu0 and arm_big_little
           cpufreq drivers from Hans Wennborg, Himangi Saraogi, Markus
           Pargmann and Uwe Kleine-König
      
         - Version 3.0 of the analyze_suspend.py suspend profiling tool from
           Todd E Brandt"
