      enic: fix rx skb checksum · 17e96834
      Govindarajulu Varadarajan authored
      Hardware always provides compliment of IP pseudo checksum. Stack expects
      whole packet checksum without pseudo checksum if CHECKSUM_COMPLETE is set.
      
      This causes checksum error in nf & ovs.

       "virtio 1.0 related fixes
      
        Most importantly, this fixes using virtio_pci as a module.
      
        Further, the big virtio 1.0 conversion missed a couple of places.
        This fixes them up.
      
        This isn't 100% sparse-clean yet because on many architectures
        get_user triggers sparse warnings when used with __bitwise tag (when
        same tag is on both pointer and value read).
      
        I posted a patchset to fix it up by adding __force on all arches that
        don't already have it (many do), when that's merged these warnings

      Pull more ACPI and power management updates from Rafael Wysocki:
       "These are regression fixes (leds-gpio, ACPI backlight driver,
        operating performance points library, ACPI device enumeration
        messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device
        PM), some cleanups in the operating performance points (OPP)
        framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of
        minor intel_pstate driver changes, a new MAINTAINERS entry for it and
        an ACPI fan driver change needed for better support of thermal
        management in user space.
      
        Specifics:
      
         - Fix a regression in leds-gpio introduced by a recent commit that
           inadvertently changed the name of one of the properties used by the
           driver (Fabio Estevam).
      
         - Fix a regression in the ACPI backlight driver introduced by a
           recent fix that missed one special case that had to be taken into
           account (Aaron Lu).
      
         - Drop the level of some new kernel messages from the ACPI core
           introduced by a recent commit to KERN_DEBUG which they should have
           used from the start and drop some other unuseful KERN_ERR messages
           printed by ACPI (Rafael J Wysocki).
      
         - Revert an incorrect commit modifying the cpupower tool (Prarit
           Bhargava).
      
         - Fix two regressions introduced by recent commits in the OPP library
           and clean up some existing minor issues in that code (Viresh
           Kumar).
      
         - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
           tree (or drop it where that can be done) in order to make it
           possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
           Hansson, Ludovic Desroches).
      
           There will be one more "CONFIG_PM_RUNTIME removal" batch after this
           one, because some new uses of it have been introduced during the
           current merge window, but that should be sufficient to finally get
           rid of it.
      
         - Make the ACPI EC driver more robust against race conditions related
           to GPE handler installation failures (Lv Zheng).
      
         - Prevent the ACPI device PM core code from attempting to disable
           GPEs that it has not enabled which confuses ACPICA and makes it
           report errors unnecessarily (Rafael J Wysocki).
      
         - Add a "force" command line switch to the intel_pstate driver to
           make it possible to override the blacklisting of some systems in
           that driver if needed (Ethan Zhao).
      
         - Improve intel_pstate code documentation and add a MAINTAINERS entry
           for it (Kristen Carlson Accardi).
      
         - Make the ACPI fan driver create cooling device interfaces witn
           names that reflect the IDs of the ACPI device objects they are
           associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").
      
           That's necessary for user space thermal management tools to be able
           to connect the fans with the parts of the system they are supposed
           to be cooling properly.  From Srinivas Pandruvada"
