           to resume runtime-suspended devices before hibernation (which
           allows some functional problems to be avoided) and fix some ACPI
           power management issues related to hiberation (Rafael Wysocki).
      
         - Extend the operating performance points (OPP) framework to support
           a wider range of devices (Rajendra Nayak, Stehpen Boyd).

       - Make the dma-iommu code more generic so that it can be used outside
         of the ARM context with other IOMMU drivers. Goal is to make use of
         it on x86 too.
      
       - Generic IOMMU domain support for the Intel VT-d driver. This driver
         now makes more use of common IOMMU code to allocate default domains
         for the devices it handles.
      
       - An IOMMU fault reporting API to userspace. With that the IOMMU fault
         handling can be done in user-space, for example to forward the faults
         to a VM.
      
       - Better handling for reserved regions requested by the firmware. These
         can be 'relaxed' now, meaning that those don't prevent a device being
         attached to a VM.
      
       - Suspend/Resume support for the Renesas IOMMU driver.
      
       - Added support for dumping SVA related fields of the DMAR table in the
         Intel VT-d driver via debugfs.

      Pull GPIO updates from Linus Walleij:
       "This is the big slew of GPIO changes for the v5.3 kernel cycle. This
        is mostly incremental work this time.
      
        Three important things:
      
         - The FMC subsystem is deleted through my tree. This happens through
           GPIO as its demise was discussed in relation to a patch decoupling
           its GPIO implementation from the standard way of handling GPIO. As
           it turns out, that is not the only subsystem it reimplements and
           the authors think it is better do scratch it and start over using
           the proper kernel subsystems than try to polish the rust shiny. See
           the commit (ACKed by the maintainers) for details.
      
         - Arnd made a small devres patch that was ACKed by Greg and goes into
           the device core.
      
         - SPDX header change colissions may happen, because at times I've
           seen that quite a lot changed during the -rc:s in regards to SPDX.
           (It is good stuff, tglx has me convinced, and it is worth the
           occasional pain.)
      
        Apart from this is is nothing controversial or problematic.
      
        Summary:
      
        Core:
      
         - When a gpio_chip request GPIOs from itself, it can now fully
           control the line characteristics, both machine and consumer flags.
           This makes a lot of sense, but took some time before I figured out
           that this is how it has to work.
      
         - Several smallish documentation fixes.
      
        New drivers:
      
         - The PCA953x driver now supports the TI TCA9539.
      
         - The DaVinci driver now supports the K3 AM654 SoCs.
      
        Driver improvements:
      
         - Major overhaul and hardening of the OMAP driver by Russell King.
      
         - Starting to move some drivers to the new API passing irq_chip along
           with the gpio_chip when adding the gpio_chip instead of adding it
           separately.
      
        Unrelated:
      
         - Delete the FMC subsystem"

      Pull force_sig() argument change from Eric Biederman:
       "A source of error over the years has been that force_sig has taken a
        task parameter when it is only safe to use force_sig with the current
        task.
      
        The force_sig function is built for delivering synchronous signals
        such as SIGSEGV where the userspace application caused a synchronous
        fault (such as a page fault) and the kernel responded with a signal.
      
        Because the name force_sig does not make this clear, and because the
        force_sig takes a task parameter the function force_sig has been
        abused for sending other kinds of signals over the years. Slowly those
        have been fixed when the oopses have been tracked down.
      
        This set of changes fixes the remaining abusers of force_sig and
        carefully rips out the task parameter from force_sig and friends
        making this kind of error almost impossible in the future"

           label deletions. The new environment, in which IMA-appraisal is

      Pull keyring ACL support from David Howells:
       "This changes the permissions model used by keys and keyrings to be
        based on an internal ACL by the following means:
      
         - Replace the permissions mask internally with an ACL that contains a
           list of ACEs, each with a specific subject with a permissions mask.
           Potted default ACLs are available for new keys and keyrings.
      
           ACE subjects can be macroised to indicate the UID and GID specified
           on the key (which remain). Future commits will be able to add
           additional subject types, such as specific UIDs or domain
           tags/namespaces.
      
           Also split a number of permissions to give finer control. Examples
           include splitting the revocation permit from the change-attributes
           permit, thereby allowing someone to be granted permission to revoke
           a key without allowing them to change the owner; also the ability
           to join a keyring is split from the ability to link to it, thereby
           stopping a process accessing a keyring by joining it and thus
           acquiring use of possessor permits.
      
         - Provide a keyctl to allow the granting or denial of one or more
           permits to a specific subject. Direct access to the ACL is not
           granted, and the ACL cannot be viewed"

      Pull keyring namespacing from David Howells:
       "These patches help make keys and keyrings more namespace aware.
      
        Firstly some miscellaneous patches to make the process easier:
      
         - Simplify key index_key handling so that the word-sized chunks
           assoc_array requires don't have to be shifted about, making it
           easier to add more bits into the key.
      
         - Cache the hash value in the key so that we don't have to calculate
           on every key we examine during a search (it involves a bunch of
           multiplications).
      
         - Allow keying_search() to search non-recursively.
      
        Then the main patches:
      
         - Make it so that keyring names are per-user_namespace from the point
           of view of KEYCTL_JOIN_SESSION_KEYRING so that they're not
           accessible cross-user_namespace.
      
           keyctl_capabilities() shows KEYCTL_CAPS1_NS_KEYRING_NAME for this.
      
         - Move the user and user-session keyrings to the user_namespace
           rather than the user_struct. This prevents them propagating
           directly across user_namespaces boundaries (ie. the KEY_SPEC_*
           flags will only pick from the current user_namespace).
      
         - Make it possible to include the target namespace in which the key
           shall operate in the index_key. This will allow the possibility of
           multiple keys with the same description, but different target
           domains to be held in the same keyring.
      
           keyctl_capabilities() shows KEYCTL_CAPS1_NS_KEY_TAG for this.
      
         - Make it so that keys are implicitly invalidated by removal of a
           domain tag, causing them to be garbage collected.
      
         - Institute a network namespace domain tag that allows keys to be
           differentiated by the network namespace in which they operate. New
           keys that are of a type marked 'KEY_TYPE_NET_DOMAIN' are assigned
           the network domain in force when they are created.
      
         - Make it so that the desired network namespace can be handed down
           into the request_key() mechanism. This allows AFS, NFS, etc. to
           request keys specific to the network namespace of the superblock.
      
           This also means that the keys in the DNS record cache are
           thenceforth namespaced, provided network filesystems pass the
           appropriate network namespace down into dns_query().
      
           For DNS, AFS and NFS are good, whilst CIFS and Ceph are not. Other
           cache keyrings, such as idmapper keyrings, also need to set the
           domain tag - for which they need access to the network namespace of
           the superblock"

       "These are all request_key()-related, including a fix and some improvements:
      
         - Fix the lack of a Link permission check on a key found by
           request_key(), thereby enabling request_key() to link keys that
           don't grant this permission to the target keyring (which must still
           grant Write permission).
      
           Note that the key must be in the caller's keyrings already to be
           found.
      
         - Invalidate used request_key authentication keys rather than
           revoking them, so that they get cleaned up immediately rather than
           hanging around till the expiry time is passed.
      
         - Move the RCU locks outwards from the keyring search functions so
           that a request_key_rcu() can be provided. This can be called in RCU
           mode, so it can't sleep and can't upcall - but it can be called
           from LOOKUP_RCU pathwalk mode.
      
         - Cache the latest positive result of request_key*() temporarily in
           task_struct so that filesystems that make a lot of request_key()
           calls during pathwalk can take advantage of it to avoid having to
           redo the searching. This requires CONFIG_KEYS_REQUEST_CACHE=y.
      
           It is assumed that the key just found is likely to be used multiple
           times in each step in an RCU pathwalk, and is likely to be reused
           for the next step too.
      
           Note that the cleanup of the cache is done on TIF_NOTIFY_RESUME,

         - Allow zero-byte writes to the "keycreate" procfs attribute without
           requiring key:create to make it easier for userspace to reset the
           keycreate label.

           in the AUDIT_SELINUX_ERR audit records"

      Pull tpm updates from Jarkko Sakkinen:
       "This contains two critical bug fixes and support for obtaining TPM
        events triggered by ExitBootServices().
      
        For the latter I have to give a quite verbose explanation not least
        because I had to revisit all the details myself to remember what was
        going on in Matthew's patches.
      
        The preboot software stack maintains an event log that gets entries
        every time something gets hashed to any of the PCR registers. What
        gets hashed could be a component to be run or perhaps log of some
        actions taken just to give couple of coarse examples. In general,
        anything relevant for the boot process that the preboot software does
        gets hashed and a log entry with a specific event type [1].
      
        The main application for this is remote attestation and the reason why
        it is useful is nicely put in the very first section of [1]:
      
           "Attestation is used to provide information about the platform’s
            state to a challenger. However, PCR contents are difficult to
            interpret; therefore, attestation is typically more useful when
            the PCR contents are accompanied by a measurement log. While not
            trusted on their own, the measurement log contains a richer set of
            information than do the PCR contents. The PCR contents are used to
            provide the validation of the measurement log."
      
        Because EFI_TCG2_PROTOCOL.GetEventLog() is not available after calling
        ExitBootServices(), Linux EFI stub copies the event log to a custom
        configuration table. Unfortunately, ExitBootServices() also generates
        events and obviously these events do not get copied to that table.
        Luckily firmware does this for us by providing a configuration table
        identified by EFI_TCG2_FINAL_EVENTS_TABLE_GUID.
      
        This essentially contains necessary changes to provide the full event
        log for the use the user space that is concatenated from these two
        partial event logs [2]"
      
      [1] https://trustedcomputinggroup.org/resource/pc-client-specific-platform-firmware-profile-specification/
      [2] The final concatenation is done in drivers/char/tpm/eventlog/efi.c
