      mmc: tegra: Implement ->set_dma_mask() · b960bc44
      Nicolin Chen authored
      The SDHCI controller on Tegra186 supports 40-bit addressing, which is
      usually enough to address all of system memory. However, if the SDHCI
      controller is behind an IOMMU, the address space can go beyond. This
      happens on Tegra186 and later where the ARM SMMU has an input address
      space of 48 bits. If the DMA API is backed by this ARM SMMU, the top-
      down IOVA allocator will cause IOV addresses to be returned that the
      SDHCI controller cannot access.
      Unfortunately, prior to the introduction of the ->set_dma_mask() host
      operation, the SDHCI core would set either a 64-bit DMA mask if the
      controller claimed to support 64-bit addressing, or a 32-bit DMA mask
      Since the full 64 bits cannot be addressed on Tegra, this had to be
      worked around in commit 68481a7e
       ("mmc: tegra: Mark 64 bit dma
      broken on Tegra186") by setting the SDHCI_QUIRK2_BROKEN_64_BIT_DMA
      quirk, which effectively restricts the DMA mask to 32 bits.
      One disadvantage of this is that dma_map_*() APIs will now try to use
      the swiotlb to bounce DMA to addresses beyond of the controller's DMA
      mask. This in turn caused degraded performance and can lead to
      situations where the swiotlb buffer is exhausted, which in turn leads
      to DMA transfers to fail.
      With the recent introduction of the ->set_dma_mask() host operation,
      this can now be properly fixed. For each generation of Tegra, the exact
      supported DMA mask can be configured. This kills two birds with one
      stone: it avoids the use of bounce buffers because system memory never
      exceeds the addressable memory range of the SDHCI controllers on these
      devices, and at the same time when an IOMMU is involved, it prevents
      IOV addresses from being allocated beyond the addressible range of the
      Since the DMA mask is now properly handled, the 64-bit DMA quirk can be

      mmc: sdhci-of-esdhc: set DMA snooping based on DMA coherence · 121bd08b
      Russell King authored
      We must not unconditionally set the DMA snoop bit; if the DMA API is
      assuming that the device is not DMA coherent, and the device snoops the
      CPU caches, the device can see stale cache lines brought in by
      speculative prefetch.
      This leads to the device seeing stale data, potentially resulting in
      corrupted data transfers.  Commonly, this results in a descriptor fetch
      error such as:
      mmc0: ADMA error

      mmc0: error -5 whilst initialising SD card
      but can lead to other errors, and potentially direct the SDHCI
      controller to read/write data to other memory locations (e.g. if a valid
      descriptor is visible to the device in a stale cache line.)
      Fix this by ensuring that the DMA snoop bit corresponds with the
      behaviour of the DMA API.  Since the driver currently only supports DT,
      use of_dma_is_coherent().  Note that device_get_dma_attr() can not be
      used as that risks re-introducing this bug if/when the driver is
      converted to ACPI.

      mmc: sdhci: improve ADMA error reporting · d1c536e3
      Russell King authored
      ADMA errors are potentially data corrupting events; although we print
      the register state, we do not usefully print the ADMA descriptors.
      Worse than that, we print them by referencing their virtual address
      which is meaningless when the register state gives us the DMA address
      of the failing descriptor.
      Print the ADMA descriptors giving their DMA addresses rather than their
      virtual addresses, and print them using SDHCI_DUMP() rather than DBG().
      We also do not show the correct value of the interrupt status register;
      the register dump shows the current value, after we have cleared the
      pending interrupts we are going to service.  What is more useful is to
      print the interrupts that _were_ pending at the time the ADMA error was
      encountered.  Fix that too.

      firmware: bcm47xx_nvram: _really_ correct size_t printf format · 5d4156ac

      Commit feb4eb06
       ("firmware: bcm47xx_nvram: Correct size_t printf

      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.

      It's an unusual configuration, and was apparently never tested, and not

      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.
         - 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.

         - boot_mem_map is removed, providing a nice cleanup made possible by
           the recent removal of bootmem.
         - Some fixes to atomics, in general providing compiler barriers for
           smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs
           or MIPS32 systems using cmpxchg64().
         - Conversion to the new generic VDSO infrastructure courtesy of
           Vincenzo Frascino.
         - Removal of undefined behavior in set_io_port_base(), fixing the
           behavior of some MIPS kernel configurations when built with recent
           clang versions.
         - Initial MIPS32 huge page support, functional on at least Ingenic
         - pte_special() is now supported for some configurations, allowing
           among other things generic fast GUP to be used.
         - Miscellaneous fixes & cleanups.
        And platform specific changes:
         - Major improvements to Ingenic SoC support from Paul Cercueil,
           mostly enabled by the inclusion of the new TCU (timer-counter unit)
           drivers he's spent a very patient year or so working on. Plus some
           fixes for X1000 SoCs from Zhou Yanjie.

         template for ESSIV generation that was factored out will also be used
         by fscrypt in the future.

         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.

      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
            #define asm_inline asm
        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"

       "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.
         - 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

      MIPS: Detect bad _PFN_SHIFT values · 05d013a0
      Paul Burton authored
      2 recent commits have fixed issues where _PFN_SHIFT grew too large due
      to the introduction of too many pgprot bits in our PTEs for some MIPS32
      kernel configurations. Tracking down such issues can be tricky, so add a
      BUILD_BUG_ON() to help.

      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
      For now, disable the pte_special() support for MIPS32 configurations
      that support RiXi.
      Fixes: 61cbfff4
