      firmware: bcm47xx_nvram: _really_ correct size_t printf format · 5d4156ac
      Linus Torvalds authored
      Commit feb4eb06 ("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.

      modules: make MODULE_IMPORT_NS() work even when modular builds are disabled · 3e4d890a
      Linus Torvalds authored
      It's an unusual configuration, and was apparently never tested, and not
      caught in linux-next because of a combination of travels and it making
      it into the tree too late.
      
      The fix is to simply move the #define to outside the CONFIG_MODULE
      section, since MODULE_INFO() will do the right thing.

      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"

         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).

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

      Pull asm inline support from Miguel Ojeda:
       "Make use of gcc 9's "asm inline()" (Rasmus Villemoes):
      
        gcc 9+ (and gcc 8.3, 7.5) provides a way to override the otherwise
        crude heuristic that gcc uses to estimate the size of the code
        represented by an asm() statement. From the gcc docs
      
            If you use 'asm inline' instead of just 'asm', then for inlining
            purposes the size of the asm is taken as the minimum size, ignoring
            how many instructions GCC thinks it is.
      
        For compatibility with older compilers, we obviously want a
      
            #if [understands asm inline]
            #define asm_inline asm inline
            #else
            #define asm_inline asm
            #endif
      
        But since we #define the identifier inline to attach some attributes,
        we have to use an alternate spelling of that keyword. gcc provides
        both __inline__ and __inline, and we currently #define both to inline,
        so they all have the same semantics.
      
        We have to free up one of __inline__ and __inline, and the latter is
        by far the easiest.
      
        The two x86 changes cause smaller code gen differences than I'd
        expect, but I think we do want the asm_inline thing available sooner
        or later, so this is just to get the ball rolling"

       "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

       "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

         - Add regulator support to the cdce925 clk driver
         - Add support for Raspberry Pi 4 bcm2711 SoCs
         - Add SDIO gate support to aspeed driver

      MIPS: Disable pte_special() for MIPS32 with RiXi · d1af2ab3
      Paul Burton authored
      Commit 61cbfff4 ("MIPS: pte_special()/pte_mkspecial() support")
      added a _PAGE_SPECIAL bit to the pgprot bits of our PTEs. Unfortunately
      for MIPS32 configurations with RiXi support this pushed the number of
      pgprot bits to 13. Since the PFN field in EntryLo begins at bit 12 this
      results in us shifting the most significant bit of the physical address
      beyond the end of the PTE, leading any mapped access to a physical
      address above 2GB to incorrectly access an address 2GB lower than
      intended.
      
      For now, disable the pte_special() support for MIPS32 configurations
      that support RiXi.

           Ultravisor.
      
         - Some changes to our DMA code on bare metal, to allow devices with
           medium sized DMA masks (> 32 && < 59 bits) to use more than 2GB of
           DMA space.
      
         - Support for firmware assisted crash dumps on bare metal (powernv).
      
         - Two series fixing bugs in and refactoring our PCI EEH code.
      
         - A large series refactoring our exception entry code to use gas
           macros, both to make it more readable and also enable some future
           optimisations.
      
        As well as many cleanups and other minor features & fixups.
