      media: vimc: set id_table for platform drivers · bb3abbb7
      Javier Martinez Canillas authored
      The vimc platform drivers define a platform device ID table but these
      are not set to the .id_table field in the platform driver structure.
      
      So the platform device ID table is only used to fill the aliases in
      the module but are not used for matching (works because the platform
      subsystem fallbacks to the driver's name if no .id_table is set).
      
      But this also means that the platform device ID table isn't used if
      the driver is built-in, which leads to the following build warning:
      
      This causes the following build warnings when the driver is built-in:

      Instead of directly using -Wno-foo, use cc-disable-warning, as it
      checks if the compiler has the warnings we want to disable.

      Pull documentation format standardization from Jonathan Corbet:
       "This series converts a number of top-level documents to the RST format
        without incorporating them into the Sphinx tree. The hope is to bring
        some uniformity to kernel documentation and, perhaps more importantly,
        have our existing docs serve as an example of the desired formatting
        for those that will be added later.
      
        Mauro has gone through and fixed up a lot of top-level documentation
        files to make them conform to the RST format, but without moving or
        renaming them in any way. This will help when we incorporate the ones
        we want to keep into the Sphinx doctree, but the real purpose is to
        bring a bit of uniformity to our documentation and let the top-level
        docs serve as examples for those writing new ones"

         - add uevents for VM creation/destruction
         - annotate and properly access RCU-protected objects
      
        s390:
         - rename IOCTL added in the first v4.13 merge
      
        x86:
         - emulate VMLOAD VMSAVE feature in SVM
         - support paravirtual asynchronous page fault while nested
         - add Hyper-V userspace interfaces for better migration
         - improve master clock corner cases
         - extend internal error reporting after EPT misconfig
         - correct single-stepping of emulated instructions in SVM
         - handle MCE during VM entry
         - fix nVMX VM entry checks and nVMX VMCS shadowing"

      random: reorder READ_ONCE() in get_random_uXX · 72e5c740
      Sebastian Andrzej Siewior authored
      Avoid the READ_ONCE in commit 4a072c71 ("random: silence compiler
      warnings and fix race") if we can leave the function after
      arch_get_random_XXX().

      random: suppress spammy warnings about unseeded randomness · eecabf56
      Theodore Ts'o authored
      Unfortunately, on some models of some architectures getting a fully
      seeded CRNG is extremely difficult, and so this can result in dmesg
      getting spammed for a surprisingly long time.  This is really bad from
      a security perspective, and so architecture maintainers really need to
      do what they can to get the CRNG seeded sooner after the system is
      booted.  However, users can't do anything actionble to address this,
      and spamming the kernel messages log will only just annoy people.
      
      For developers who want to work on improving this situation,
      CONFIG_WARN_UNSEEDED_RANDOM has been renamed to
      CONFIG_WARN_ALL_UNSEEDED_RANDOM.  By default the kernel will always
      print the first use of unseeded randomness.  This way, hopefully the
      security obsessed will be happy that there is _some_ indication when
      the kernel boots there may be a potential issue with that architecture
      or subarchitecture.  To see all uses of unseeded randomness,
      developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM.
