      remoteproc: qcom: Add support for SSR notifications · 1e140df0
      Bjorn Andersson authored
      This adds the remoteproc part of subsystem restart, which is responsible
      for emitting notifications to other processors in the system about a
      dying remoteproc instance.
      These notifications are propagated to the various communication systems
      in the various remote processors to shut down communication links that
      was left in a dangling state as the remoteproc was stopped (or crashed).

      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"

      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.

           switching over the EC into the polling mode during the noirq stages
           of system suspend and resume (Lv Zheng).
         - Add quirks for ACPI device objects that need to be treated as

       "These fix a recently exposed issue in the PCI device wakeup code and
        one older problem related to PCI device wakeup that has been reported
        recently, modify one more piece of computations in intel_pstate to get

        invalid user input, fix return values of two probe routines in devfreq

         - Avoid clearing the PCI PME Enable bit for devices as a result of
           config space restoration which confuses AML executed afterward and
           causes wakeup events to be lost on some systems (Rafael Wysocki).
         - Fix the native PCIe PME interrupts handling in the cases when the
           PME IRQ is set up as a system wakeup one so that runtime PM remote
           wakeup works as expected after system resume on systems where that
           happens (Rafael Wysocki).
         - Fix the device PM QoS sysfs interface to handle invalid user input
           correctly instead of using an unititialized variable value as the
           latency tolerance for the device at hand (Dan Carpenter).
         - Get rid of one more rounding error from intel_pstate computations
           (Srinivas Pandruvada).
         - Fix the schedutil cpufreq governor to prevent it from possibly
           accessing unititialized data structures from governor callbacks in
           some cases on systems when multiple CPUs share a single cpufreq
           policy object (Vikram Mulukutla).

      replace incorrect strscpy use in FORTIFY_SOURCE · 077d2ba5
      Daniel Micay authored
      Using strscpy was wrong because FORTIFY_SOURCE is passing the maximum
      possible size of the outermost object, but strscpy defines the count
      parameter as the exact buffer size, so this could copy past the end of
      the source.  This would still be wrong with the planned usage of
      __builtin_object_size(p, 1) for intra-object overflow checks since it's
      the maximum possible size of the specified object with no guarantee of
      it being that large.
      Reuse of the fortified functions like this currently makes the runtime
      error reporting less precise but that can be improved later on.
      Noticed by Dave Jones and KASAN.
