      net: fec: add Wake-on-LAN support · de40ed31
      Nimrod Andy authored
      Support for Wake-on-LAN using Magic Packet. ENET IP supports sleep mode
      in low power status, when system enter suspend status, Magic packet can
      wake up system even if all SOC clocks are gate. The patch doing below things:
      - flagging the device as a wakeup source for the system, as well as
        its Wake-on-LAN interrupt
      - prepare the hardware for entering WoL mode
      - add standard ethtool WOL interface
      - enable the ENET interrupt to wake us
      
      Tested on i.MX6q/dl sabresd, sabreauto boards, i.MX6SX arm2 boards.

      genetlink: A genl_bind() to an out-of-range multicast group should not WARN(). · dc97a1a9
      David S. Miller authored
      Users can request to bind to arbitrary multicast groups, so warning
      when the requested group number is out of range is not appropriate.
      
      And with the warning removed, and the 'err' variable properly given
      an initial value, we can remove 'found' altogether.

      Pull thermal management updates from Zhang Rui:
       "First of all, the most important change is the thermal cpu cooling
        fixes.  The major fix here is to have proper sequencing between
        cpufreq layer and thermal cpu cooling registration.  A take away of
        this fix is an improvement in the thermal drivers code.  Thermal
        drivers that require cpu cooling do not need to check for cpufreq
        layer.  The requirement now is to propagate the error code, if any,
        while registering cpu cooling device.  Thanks to Viresh for
        implementing the required CPUfreq changes.
      
        Second, a new driver is introduced for int340x processor thermal
        device.  Given that int340x thermal is disabled by default, and this
        processor thermal device is only available on limited platforms, plus
        the driver does nothing but exposes some thermal limitation
        information for user space to use, thus I think it is safe to include
        it in this pull request after missing 3.19-rc2.
      
        Specifics:
      
         - Thermal cpu cooling fixes and cleanups.
      
         - introduce INT340X processor thermal reporting device driver.

      mm: get rid of radix tree gfp mask for pagecache_get_page · 45f87de5
      Michal Hocko authored
      Commit 2457aec6 ("mm: non-atomically mark page accessed during page
      cache allocation where possible") has added a separate parameter for
      specifying gfp mask for radix tree allocations.
      
      Not only this is less than optimal from the API point of view because it
      is error prone, it is also buggy currently because
      grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if
      fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by
      AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then
      the radix tree allocation wouldn't obey the restriction and might
      recurse into filesystem and cause deadlocks.  This is the case for most
      filesystems unfortunately because only ext4 and gfs2 are using
      AOP_FLAG_NOFS.
      
      Let's simply remove radix_gfp_mask parameter because the allocation
      context is same for both page cache and for the radix tree.  Just make
      sure that the radix tree gets only the sane subset of the mask (e.g.  do
      not pass __GFP_WRITE).
      
      Long term it is more preferable to convert remaining users of
      AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this
      interface even further.
