      Pull GFS2 updates from Bob Peterson:
       "We've got eight GFS2 patches for this merge window:
      
         - Andreas Gruenbacher has four patches related to cleaning up the
           GFS2 inode evict process. This is about half of his patches
           designed to fix a long-standing GFS2 hang related to the inode
           shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
           memory and blocks on the shrinker.
      
           These four patches have been well tested. His second set of patches
           are still being tested, so I plan to hold them until the next merge
           window, after we have more weeks of testing. The first patch
           eliminates the flush_delayed_work, which can block.
      
         - Andreas's second patch protects setting of gl_object for rgrps with
           a spin_lock to prevent proven races.
      
         - His third patch introduces a centralized mechanism for queueing
           glock work with better reference counting, to prevent more races.
      
          -His fourth patch retains a reference to inode glocks when an error
           occurs while creating an inode. This keeps the subsequent evict
           from needing to reacquire the glock, which might call into DLM and
           block in low memory conditions.
      
         - Arvind Yadav has a patch to add const to attribute_group
           structures.
      
         - I have a patch to detect directory entry inconsistencies and
           withdraw the file system if any are found. Better that than silent
           corruption.
      
         - I have a patch to remove a vestigial variable from glock
           structures, saving some slab space.
      
         - I have another patch to remove a vestigial variable from the GFS2
           in-core superblock structure"

      Cavium CNN55XX: fix broken default Kconfig entry · b4b8cbf6
      Linus Torvalds authored
      Every developer always thinks that _their_ code is so special and
      magical that it should be enabled by default.
      
      And most of them are completely and utterly wrong.  That's definitely
      the case when you write a specialty driver for a very unsual "security
      processor". It does *not* get to mark itself as "default m".
      
      If you solve world hunger, and make a driver that cures people of
      cancer, by all means enable it by default.  But afaik, the Cavium
      CNN55XX does neither.
