        and some braswell feature removal that the hw actually didn't support.
      
        One radeon race fix at boot, and one hlcdc build fix, one fix from
        Russell that fixes build as well with new audio features.
      
        This is hopefully all I have until -next"

      Revert of a VBT parsing commit that should've been queued for drm-next,
      not v4.2. The revert unbreaks Braswell among other things.
      
      Also on Braswell removal of DP HBR2/TP3 and intermediate eDP frequency
      support. The code was optimistically added based on incorrect
      documentation; the platform does not support them. These are cc: stable.
      
      Finally a gpu state fix from Chris, also cc: stable.

      x86/xen: make CONFIG_XEN depend on CONFIG_X86_LOCAL_APIC · 87ffd2b9
      David Vrabel authored
      Since commit feb44f1f (x86/xen:
      Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need
      a full APIC driver and thus should depend on X86_LOCAL_APIC.
      
      This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by
      disabling Xen support in this configuration.
      
      Users needing Xen support in a non-SMP i386 kernel will need to enable
      CONFIG_X86_UP_APIC.

      be2net: avoid vxlan offloading on multichannel configs · af19e686
      Ivan Vecera authored
      VxLAN offloading is not functional if the NIC is running in multichannel
      mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole
      connectivity through the NIC and the device needs to be down and up to
      restore it. The firmware should take care about it and does not allow
      the conversion of interface to tunnel type (be_cmd_manage_iface) or should
      support VxLAN offloading if multichannel config is enabled.
      I have tested this on the latest available firmware (10.6.144.21).
      
      Result:

      ====================
      ipv6: Fix a potential deadlock when creating pcpu rt
      
      v1 -> v2:
      A minor change in the commit message of patch 2.
      
      This patch series fixes a potential deadlock when creating a pcpu rt.
      It happens when dst_alloc() decided to run gc. Something like this:
      
      read_lock(&table->tb6_lock);
      ip6_rt_pcpu_alloc()
      => dst_alloc()
      => ip6_dst_gc()
      => write_lock(&table->tb6_lock); /* oops */
      
      Patch 1 and 2 are some prep works.
      Patch 3 is the fix.

      ipv6: Fix a potential deadlock when creating pcpu rt · 9c7370a1
      Martin KaFai Lau authored
      rt6_make_pcpu_route() is called under read_lock(&table->tb6_lock).
      rt6_make_pcpu_route() calls ip6_rt_pcpu_alloc(rt) which then
      calls dst_alloc().  dst_alloc() _may_ call ip6_dst_gc() which takes
      the write_lock(&tabl->tb6_lock).  A visualized version:
      
      read_lock(&table->tb6_lock);
      rt6_make_pcpu_route();
      => ip6_rt_pcpu_alloc();
      => dst_alloc();
      => ip6_dst_gc();
      => write_lock(&table->tb6_lock); /* oops */
      
      The fix is to do a read_unlock first before calling ip6_rt_pcpu_alloc().

      ipv6: Add rt6_make_pcpu_route() · a73e4195
      Martin KaFai Lau authored
      It is a prep work for fixing a potential deadlock when creating
      a pcpu rt.
      
      The current rt6_get_pcpu_route() will also create a pcpu rt if one does not
      exist.  This patch moves the pcpu rt creation logic into another function,
      rt6_make_pcpu_route().

      After 4b32b5ad ("ipv6: Stop rt6_info from using inet_peer's metrics"),
      ip6_dst_alloc() does not need the 'table' argument.  This patch

      net: phy: workaround for buggy cable detection by LAN8700 after cable plugging · 776829de
      Igor Plyatov authored
      * Due to HW bug, LAN8700 sometimes does not detect presence of energy in the
        Ethernet cable in Energy Detect Power-Down mode (e.g while EDPWRDOWN bit is
        set, the ENERGYON bit does not asserted sometimes). This is a common bug of
        LAN87xx family of PHY chips.
      * The lan87xx_read_status() was improved to acquire ENERGYON bit. Its previous
        algorythm still not reliable on 100 % and sometimes skip cable plugging.
