  • For pages that were retained via get_user_pages*(), release those pages
    via the new put_user_page*() routines, instead of via put_page() or
    release_pages().

    This is part a tree-wide conversion, as described in fc1d8e7cca2d ("mm:
    introduce put_user_page*(), placeholder versions").

    Also reverse the order of a comparison, in order to placate checkpatch.pl.

    Subject: mm/gup: add make_dirty arg to put_user_pages_dirty_lock()

    Patch series "mm/gup: add make_dirty arg to put_user_pages_dirty_lock()",
    v3.

    There are about 50+ patches in my tree [2], and I'll be sending out the
    remaining ones in a few more groups:

    * The block/bio related changes (Jerome mostly wrote those, but I've had
    to move stuff around extensively, and add a little code)

    * mm/ changes

    * other subsystem patches

    * an RFC that shows the current state of the tracking patch set. That
    can only be applied after all call sites are converted, but it's good to
    get an early look at it.

    This is part a tree-wide conversion, as described in fc1d8e7cca2d ("mm:
    introduce put_user_page*(), placeholder versions").

    This patch (of 3):

    Provide more capable variation of put_user_pages_dirty_lock(), and delete
    put_user_pages_dirty(). This is based on the following:

    1. Lots of call sites become simpler if a bool is passed into
    put_user_page*(), instead of making the call site choose which
    put_user_page*() variant to call.

    2. Christoph Hellwig's observation that set_page_dirty_lock() is
    usually correct, and set_page_dirty() is usually a bug, or at least
    questionable, within a put_user_page*() calling chain.

    This leads to the following API choices:

    * put_user_pages_dirty_lock(page, npages, make_dirty)

    * There is no put_user_pages_dirty(). You have to
    hand code that, in the rare case that it's
    required.

  • Patch series "Make working with compound pages easier", v2.

    These three patches add three helpers and convert the appropriate
    places to use them.

    This patch (of 3):

    It's unnecessarily hard to find out the size of a potentially huge page.
    Replace 'PAGE_SIZE << compound_order(page)' with page_size(page).

  • Commit feb4eb060c3a ("firmware: bcm47xx_nvram: Correct size_t printf
    format") was wrong, and changed a printout of 'header.len' - which is an
    u32 type - to use '%zu'.

    It apparently did pattern matching on the other case, where it printed
    out 'nvram_len', which is indeed of type 'size_t'.

    Rather than undoing the change, this just makes it use the variable that
    the change seemed to expect to be used.

  • Pull modules updates from Jessica Yu:
    "The main bulk of this pull request introduces a new exported symbol
    namespaces feature. The number of exported symbols is increasingly
    growing with each release (we're at about 31k exports as of 5.3-rc7)
    and we currently have no way of visualizing how these symbols are
    "clustered" or making sense of this huge export surface.

    Namespacing exported symbols allows kernel developers to more
    explicitly partition and categorize exported symbols, as well as more
    easily limiting the availability of namespaced symbols to other parts
    of the kernel. For starters, we have introduced the USB_STORAGE
    namespace to demonstrate the API's usage. I have briefly summarized
    the feature and its main motivations in the tag below.

    Summary:

    - Introduce exported symbol namespaces.

    This new feature allows subsystem maintainers to partition and
    categorize their exported symbols into explicit namespaces. Module
    authors are now required to import the namespaces they need.

    Some of the main motivations of this feature include: allowing
    kernel developers to better manage the export surface, allow
    subsystem maintainers to explicitly state that usage of some
    exported symbols should only be limited to certain users (think:
    inter-module or inter-driver symbols, debugging symbols, etc), as
    well as more easily limiting the availability of namespaced symbols
    to other parts of the kernel.

    With the module import requirement, it is also easier to spot the
    misuse of exported symbols during patch review.

    Two new macros are introduced: EXPORT_SYMBOL_NS() and
    EXPORT_SYMBOL_NS_GPL(). The API is thoroughly documented in
    Documentation/kbuild/namespaces.rst.

    - Some small code and kbuild cleanups here and there"

    - crypto and DM crypt advances that allow the crypto API to reclaim
    implementation details that do not belong in DM crypt. The wrapper
    template for ESSIV generation that was factored out will also be used
    by fscrypt in the future.

    - Add root hash pkcs#7 signature verification to the DM verity target.

    - Add a new "clone" DM target that allows for efficient remote
    replication of a device.

    - Enhance DM bufio's cache to be tailored to each client based on use.
    Clients that make heavy use of the cache get more of it, and those
    that use less have reduced cache usage.

    - Add a new DM_GET_TARGET_VERSION ioctl to allow userspace to query the
    version number of a DM target (even if the associated module isn't
    yet loaded).

    - Fix invalid memory access in DM zoned target.

    - Fix the max_discard_sectors limit advertised by the DM raid target;
    it was mistakenly storing the limit in bytes rather than sectors.

    round out the series:

    - General improvement of hmm_range_fault() and related APIs, more

  • Pull ARM SoC late updates from Arnd Bergmann:
    "This is some material that we picked up into our tree late or that had
    complex inter-depondencies. The fact that there are these
    interdependencies tends to meant that these are often actually the
    most interesting new additions:

    - The new Aspeed AST2600 baseboard management controller is added,
    this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and
    had some dependencies on other device drivers.

    - After many years, support for the MMP2 based OLPC XO-1.75 finally
    makes it into the kernel.

    - The Armada 3720 based Turris Mox open source router platform is a
    late addition and it follows some preparatory work across multiple
    branches.

    - The OMAP2+ platform had some large-scale cleanup involving driver
    changes and DT changes, here we finish it off, dropping a lot of
    the now-unused platform data.

    - The TI K3 platform that got added for 5.3 gains a lot more support
    for individual bits on the SoC, this part just came late for the
    merge window"

    [ This pull request itself wasn't actually sent late at all by Arnd, but
    I waited on the branches that it used to be pulled first, so it ends
    up being merged much later than the other ARM SoC pull requests this
    merge window - Linus ]

  • Pull clk updates from Stephen Boyd:
    "We have a small collection of core framework updates this time, mostly
    around clk registration by clk providers and debugfs "nice to haves"
    for rate constraints. I'll highlight that we're now setting the
    clk_init_data pointer inside struct clk_hw to NULL during
    clk_register(), which may break some drivers that thought they could
    use that pointer during normal operations. That change has been
    sitting in next for a while now but maybe something is still broken.
    We'l see. Other than that the core framework changes aren't invasive
    and they're fixing bugs, simplifying, and making things better.

    On the clk driver side we got the usual addition of new SoC support,
    new features for existing drivers, and bug fixes scattered throughout.
    The biggest diffstat is the Amlogic driver that gained CPU clk support
    in addition to migrating to the new way of specifying clk parents.
    After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got
    support for various new SoCs and clock controllers from those vendors.

    Core:
    - Drop NULL checks in clk debugfs
    - Add min/max rates to clk debugfs
    - Set clk_init_data pointer inside clk_hw to NULL after registration
    - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
    - Evict parents from parent cache when they're unregistered

    New Drivers:
    - Add clock driver for i.MX8MN SoCs
    - Support aspeed AST2600 SoCs
    - Support for Mediatek MT6779 SoCs
    - Support qcom SM8150 GCC and RPMh clks
    - Support qcom QCS404 WCSS clks
    - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
    - Addition of clock driver for Rockchip rk3308 SoCs

    Updates:
    - Add regulator support to the cdce925 clk driver
    - Add support for Raspberry Pi 4 bcm2711 SoCs
    - Add SDIO gate support to aspeed driver
    - Add missing of_node_put() calls in various clk drivers
    - Migrate Amlogic driver to new clock parent description method
    - Add DVFS support to Amlogic Meson g12
    - Add Amlogic Meson g12a reset support to the axg audio clock controller
    - Add sm1 support to the Amlogic Meson g12a clock controller

  • Pull drm updates from Dave Airlie:
    "This is the main pull request for 5.4-rc1 merge window. I don't think
    there is anything outstanding so next week should just be fixes, but
    we'll see if I missed anything. I landed some fixes earlier in the
    week but got delayed writing summary and sending it out, due to a mix
    of sick kid and jetlag!

    There are some fixes pending, but I'd rather get the main merge out of
    the way instead of delaying it longer.

    It's also pretty large in commit count and new amd header file size.
    The largest thing is four new amdgpu products (navi12/14, arcturus and
    renoir APU support).

    Otherwise it's pretty much lots of work across the board, i915 has
    started landing tigerlake support, lots of icelake fixes and lots of
    locking reworking for future gpu support, lots of header file rework
    (drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been
    put into the places they are needed.

    uapi:
    - content protection type property for HDCP

  • These recursive functions have checks for !clk being passed in, but the

    can't be NULL. Drop the checks to simplify the code.
