      ACPI / platform: Initialize ACPI handles of platform devices in advance · 863f9f30
      Rafael J. Wysocki 提交于
      The current platform device creation and registration code in
      acpi_create_platform_device() is quite convoluted.  This function
      takes an ACPI device node as an argument and eventually calls
      platform_device_register_resndata() to create and register a
      platform device object on the basis of the information contained
      in that code.  However, it doesn't associate the new platform
      device with the ACPI node directly, but instead it relies on
      acpi_platform_notify(), called from within device_add(), to find
      that ACPI node again with the help of acpi_platform_find_device()
      and acpi_platform_match() and then attach the new platform device
      to it.  This causes an additional ACPI namespace walk to happen and
      is clearly suboptimal.
      
      Use the observation that it is now possible to initialize the ACPI
      handle of a device before calling device_add() for it to make this
      code more straightforward.  Namely, add a new field to struct
      platform_device_info allowing us to pass the ACPI handle of interest
      to platform_device_register_full(), which will then use it to
      initialize the new device's ACPI handle before registering it.
      This will cause acpi_platform_notify() to use the ACPI handle from
      the device structure directly instead of using the .find_device()
      routine provided by the device's bus type.  In consequence,
      acpi_platform_bus, acpi_platform_find_device(), and
      acpi_platform_match() are not necessary any more, so remove them.

      ACPI / driver core: Introduce struct acpi_dev_node and related macros · 95f8a082
      Rafael J. Wysocki 提交于
      To avoid adding an ACPI handle pointer to struct device on
      architectures that don't use ACPI, or generally when CONFIG_ACPI is
      not set, in which cases that pointer is useless, define struct
      acpi_dev_node that will contain the handle pointer if CONFIG_ACPI is
      set and will be empty otherwise and use it to represent the ACPI
      device node field in struct device.
      
      In addition to that define macros for reading and setting the ACPI
      handle of a device that don't generate code when CONFIG_ACPI is
      unset.  Modify the ACPI subsystem to use those macros instead of
      referring to the given device's ACPI handle directly.

      ACPI: Allow ACPI handles of devices to be initialized in advance · f3fd0c8a
      Rafael J. Wysocki 提交于
      Currently, the ACPI handles of devices are initialized from within
      device_add(), by acpi_bind_one() called from acpi_platform_notify()
      which first uses the .find_device() routine provided by the device's
      bus type to find the matching device node in the ACPI namespace.
      This is a source of some computational overhead and, moreover, the
      correctness of the result depends on the implementation of
      .find_device() which is known to fail occasionally for some bus types
      (e.g. PCI).  In some cases, however, the corresponding ACPI device
      node is known already before calling device_add() for the given
      struct device object and the whole .find_device() dance in
      acpi_platform_notify() is then simply unnecessary.
      
      For this reason, make it possible to initialize the ACPI handles of
      devices before calling device_add() for them.  Modify
      acpi_platform_notify() to call acpi_bind_one() in advance to check
      the device's existing ACPI handle and skip the .find_device()
      search if that is successful.  Change acpi_bind_one() accordingly.

      Pull networking fixes from David Miller:
       "Bug fixes galore, mostly in drivers as is often the case:
      
        1) USB gadget and cdc_eem drivers need adjustments to their frame size
           lengths in order to handle VLANs correctly.  From Ian Coolidge.
      
        2) TIPC and several network drivers erroneously call tasklet_disable
           before tasklet_kill, fix from Xiaotian Feng.
      
        3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
           fix from Cyril Brulebois.
      
        4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
           Nathan Walp.
      
        5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
           zero.  From John Fastabend.
      
        6) Fix smsc95xx tx checksum offload on big-endian, from Steve
           Glendinning.
      
        7) __inet_diag_dump() needs to repsect and report the error value
           returned from inet_diag_lock_handler() rather than ignore it.
           Otherwise if an inet diag handler is not available for a particular
           protocol, we essentially report success instead of giving an error
           indication.  Fix from Cyrill Gorcunov.
      
        8) When the QFQ packet scheduler sees TSO/GSO packets it does not
           handle things properly, and in fact ends up corrupting it's
           datastructures as well as mis-schedule packets.  Fix from Paolo
           Valente.
      
        9) Fix oopser in skb_loop_sk(), from Eric Leblond.
      
        10) CXGB4 passes partially uninitialized datastructures in to FW
            commands, fix from Vipul Pandya.
      
        11) When we send unsolicited ipv6 neighbour advertisements, we should
            send them to the link-local allnodes multicast address, as per
            RFC4861.  Fix from Hannes Frederic Sowa.
      
        12) There is some kind of bug in the usbnet's kevent deferral
            mechanism, but more immediately when it triggers an uncontrolled
            stream of kernel messages spam the log.  Rate limit the error log
            message triggered when this problem occurs, as sending thousands
            of error messages into the kernel log doesn't help matters at all,
            and in fact makes further diagnosis more difficult.
      
            From Steve Glendinning.
      
        13) Fix gianfar restore from hibernation, from Wang Dongsheng.
      
        14) The netlink message attribute sizes are wrong in the ipv6 GRE
            driver, it was using the size of ipv4 addresses instead of ipv6
            ones :-) Fix from Nicolas Dichtel."

      Pull sparc fixes from David Miller:
       "Several build/bug fixes for sparc, including:
      
        1) Configuring a mix of static vs.  modular sparc64 crypto modules
           didn't work, remove an ill-conceived attempt to only have to build
           the device match table for these drivers once to fix the problem.
      
           Reported by Meelis Roos.
      
        2) Make the montgomery multiple/square and mpmul instructions actually
           usable in 32-bit tasks.  Essentially this involves providing 32-bit
           userspace with a way to use a 64-bit stack when it needs to.
      
        3) Our sparc64 atomic backoffs don't yield cpu strands properly on
           Niagara chips.  Use pause instruction when available to achieve
           this, otherwise use a benign instruction we know blocks the strand
           for some time.
      
        4) Wire up kcmp
      
        5) Fix the build of various drivers by removing the unnecessary
           blocking of OF_GPIO when SPARC.
      
        6) Fix unintended regression wherein of_address_to_resource stopped
           being provided.  Fix from Andreas Larsson.
