       "Three more changes.
      
         - I forgot that I had another selftest to stress test the ftrace
           instance creation.  It was actually suppose to go into the 4.6
           merge window, but I never committed it.  I almost forgot about it
           again, but noticed it was missing from your tree.
      
         - Soumya PN sent me a clean up patch to not disable interrupts when
           taking the tasklist_lock for read, as it's unnecessary because that
           lock is never taken for write in irq context.
      
         - Newer gcc's can cause the jump in the function_graph code to the
           global ftrace_stub label to be a short jump instead of a long one.
           As that jump is dynamically converted to jump to the trace code to
           do function graph tracing, and that conversion expects a long jump
           it can corrupt the ftrace_stub itself (it's directly after that
           call).  One way to prevent gcc from using a short jump is to
           declare the ftrace_stub as a weak function, which we do here to
           keep gcc from optimizing too much"

      x86: remove more uaccess_32.h complexity · bd28b145
      Linus Torvalds authored
      I'm looking at trying to possibly merge the 32-bit and 64-bit versions
      of the x86 uaccess.h implementation, but first this needs to be cleaned
      up.
      
      For example, the 32-bit version of "__copy_from_user_inatomic()" is
      mostly the special cases for the constant size, and it's actually almost
      never relevant.  Most users aren't actually using a constant size
      anyway, and the few cases that do small constant copies are better off
      just using __get_user() instead.
      
      So get rid of the unnecessary complexity.

      So get rid of the unnecessary complexity.
      
      [ The same cleanup should likely happen to __copy_from_user_inatomic()
        as well, but that one has a lot more users that I need to take a look
        at first ]

      Merge tag 'for-f2fs-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs · f6c658df
      Linus Torvalds authored
      Pull f2fs updates from Jaegeuk Kim:
       "In this round, as Ted pointed out, fscrypto allows one more key prefix
        given by filesystem to resolve backward compatibility issues.  Other
        than that, we've fixed several error handling cases by introducing
        a fault injection facility.  We've also achieved performance
        improvement in some workloads as well as a bunch of bug fixes.
      
        Summary:
      
        Enhancements:
         - fs-specific prefix for fscrypto
         - fault injection facility
         - expose validity bitmaps for user to be aware of fragmentation
         - fallocate/rm/preallocation speed up
         - use percpu counters
      
        Bug fixes:
         - some inline_dentry/inline_data bugs
         - error handling for atomic/volatile/orphan inodes
         - recover broken superblock"

       "This has our merge window series of cleanups and fixes.  These target
        a wide range of issues, but do include some important fixes for
        qgroups, O_DIRECT, and fsync handling.  Jeff Mahoney moved around a
        few definitions to make them easier for userland to consume.
      
        Also whiteout support is included now that issues with overlayfs have
        been cleared up.
      
        I have one more fix pending for page faults during btrfs_copy_from_user,
