      Pull apparmor updates from John Johansen:
       "This is the apparmor pull request, similar to SELinux and seccomp.
      
        It's the same series that I was sent to James' security tree + one
        regression fix that was found after the series was sent to James and
        would have been sent for v4.14-rc2.
      
        Features:
        - in preparation for secid mapping add support for absolute root view
          based labels
        - add base infastructure for socket mediation
        - add mount mediation
        - add signal mediation
      
        minor cleanups and changes:
        - be defensive, ensure unconfined profiles have dfas initialized
        - add more debug asserts to apparmorfs
        - enable policy unpacking to audit different reasons for failure
        - cleanup conditional check for label in label_print
        - Redundant condition: prev_ns. in [label.c:1498]
      
        Bug Fixes:
        - fix regression in apparmorfs DAC access permissions
        - fix build failure on sparc caused by undeclared signals
        - fix sparse report of incorrect type assignment when freeing label proxies
        - fix race condition in null profile creation
        - Fix an error code in aafs_create()
        - Fix logical error in verify_header()

       "These fix a cpufreq regression introduced by recent changes related to
        the generic DT driver, an initialization time memory leak in cpuidle
        on ARM, a PM core bug that may cause system suspend/resume to fail on
        some systems, a request type validation issue in the PM QoS framework
        and two documentation-related issues.
      
        Specifics:
      
         - Fix a regression in cpufreq on systems using DT as the source of
           CPU configuration information where two different code paths
           attempt to create the cpufreq-dt device object (there can be only
           one) and fix up the "compatible" matching for some TI platforms on
           top of that (Viresh Kumar, Dave Gerlach).
      
         - Fix an initialization time memory leak in cpuidle on ARM which
           occurs if the cpuidle driver initialization fails (Stefan Wahren).
      
         - Fix a PM core function that checks whether or not there are any
           system suspend/resume callbacks for a device, but forgets to check
           legacy callbacks which then may be skipped incorrectly and the
           system may crash and/or the device may become unusable after a
           suspend-resume cycle (Rafael Wysocki).
      
         - Fix request type validation for latency tolerance PM QoS requests
           which may lead to unexpected behavior (Jan Schönherr).
      
         - Fix a broken link to PM documentation from a header file and a typo

      apparmor: fix apparmorfs DAC access permissions · bf81100f
      John Johansen authored
      The DAC access permissions for several apparmorfs files are wrong.
      
      .access - needs to be writable by all tasks to perform queries
      the others in the set only provide a read fn so should be read only.
      
      With policy namespace virtualization all apparmor needs to control
      the permission and visibility checks directly which means DAC
      access has to be allowed for all user, group, and other.

      Generally unconfined has early bailout tests and does not need the
      dfas initialized, however if an early bailout test is ever missed
      it will result in an oops.
      
      Be defensive and initialize the unconfined profile to have null dfas
      (no permission) so if an early bailout test is missed we fail
      closed (no perms granted) instead of oopsing.

      apparmor: fix race condition in null profile creation · 290638a5
      John Johansen authored
      
      
      There is a race when null- profile is being created between the
      initial lookup/creation of the profile and lock/addition of the
      profile. This could result in multiple version of a profile being
      added to the list which need to be removed/replaced.
      
      Since these are learning profile their is no affect on mediation.

      Add signal mediation where the signal can be mediated based on the

      of incremental policy load/replacement.

      to be consistent (single compile unit) remains to be done.

      We accidentally forgot to set the error code on this path.  It means we
      return NULL instead of an error pointer.  I looked through a bunch of
      callers and I don't think it really causes a big issue, but the

        week it's a bit bigger, though not ridiculous. Hopefully things will
        settle down from here on.
      
        Four fixes for the new instruction emulation code. A fix for CPU
        offline on bare metal machines when certain idle states are not

        hotplug, caused by recent changes.
      
        Going to stable are a fix for an oops during core dump on machines
        that have TM (Transactional Memory) disabled. Reordering some EEH
        initialisation to avoid trashing memory, and another device_node
