      Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtc · 9fffb55f
      David Gibson authored
      
      
      The powerpc kernel always requires an Open Firmware like device tree
      to supply device information.  On systems without OF, this comes from
      a flattened device tree blob.  This blob is usually generated by dtc,
      a tool which compiles a text description of the device tree into the
      flattened format used by the kernel.  Sometimes, the bootwrapper makes
      small changes to the pre-compiled device tree blob (e.g. filling in
      the size of RAM).  To do this it uses the libfdt library.
      
      Because these are only used on powerpc, the code for both these tools
      is included under arch/powerpc/boot (these were imported and are
      periodically updated from the upstream dtc tree).
      
      However, the microblaze architecture, currently being prepared for
      merging to mainline also uses dtc to produce device tree blobs.  A few
      other archs have also mentioned some interest in using dtc.
      Therefore, this patch moves dtc and libfdt from arch/powerpc into
      scripts, where it can be used by any architecture.
      
      The vast bulk of this patch is a literal move, the rest is adjusting
      the various Makefiles to use dtc and libfdt correctly from their new
      locations.

      ibft: fix the display of a few fields in the NIC attribute structure in sysfs · 65fd2105

      Fix the display of a few fields in the iBFT NIC attribute structure in
      sysfs.
      
      Ensure that, if the DHCP IP address and the subnet mask for the interface
      is present in the iBFT NIC structure, the corresponding entries are
      created in sysfs tree for the device.  This would hence create the
      additional entries in the tree based on the iBFT table and would not
      delete any existing entries.

      Local variable `scan' can overflow on zones which are larger than

      Making it 64-bit on 64-bit will fix that up.

      kernel-doc: restrict syntax for private: and public: · 52dc5aec
      Randy Dunlap authored
      
      
      scripts/kernel-doc can (incorrectly) delete struct members that are
      surrounded by /* ...  */ <struct members> /* ...  */ if there is a /*
      private: */ comment in there somewhere also.
      
      Fix that by making the "/* private:" only allow whitespace between /* and
      "private:", not anything/everything in the world.
      
      This fixes some erroneous kernel-doc warnings that popped up while
      processing include/linux/usb/composite.h.

      mm: fix Committed_AS underflow on large NR_CPUS environment · 00a62ce9

      The Committed_AS field can underflow in certain situations:

      Because NR_CPUS can be greater than 1000 and meminfo_proc_show() does
      not check for underflow.
      
      But NR_CPUS proportional isn't good calculation.  In general,
      possibility of lock contention is proportional to the number of online
      cpus, not theorical maximum cpus (NR_CPUS).
      
      The current kernel has generic percpu-counter stuff.  using it is right
      way.  it makes code simplify and percpu_counter_read_positive() don't
      make underflow issue.
