      Linus Torvalds authored
      Pull powerpc updates from Michael Ellerman:
       "Highlights include:
      
         - Support for direct mapped LPC on POWER9, giving Linux direct access
           to devices that may be on there such as a UART.
      
         - Memory hotplug support for the Power9 Radix MMU.
      
         - Add new AUX vectors describing the processor's cache geometry, to
           be used by glibc.
      
         - The ability for a guest to ask the hypervisor to resize the guest's
           hash table, and in addition support for doing so automatically when
           memory is hotplugged into/out-of the guest. This allows the hash
           table to be sized based on the current memory usage of the guest,
           rather than the maximum possible memory usage.
      
         - Implementation of optprobes (kprobe optimisation) for powerpc.
      
        In addition there's the topic branch shared with the KVM tree, which
        includes support for guests to use the Radix MMU on Power9.

      Pull pin control updates from Linus Walleij:
       "Pin control bulk changes for the v4.11 kernel cycle.
      
        Core changes:
      
         - Switch the generic pin config argument from 16 to 24 bits, only use
           8 bits for the configuration type. We might need to encode more
           information about a certain setting than we need to encode
           different generic settings.
      
         - Add a cross-talk API to the pin control GPIO back-end, utilizing
           pinctrl_gpio_set_config() from GPIO drivers that want to set up a
           certain pin configuration in the back-end.
      
           This also includes the .set_config() refactoring of the GPIO chips,
           so that they pass a generic configuration for things like
           debouncing and single ended (typically open drain). This change has
           also been merged in an immutable branch to the GPIO tree.
      
         - Take hogs with a delayed work, so that we finalize probing a pin
           controller before trying to get any hogs.
      
         - For pin controllers putting all group and function definitions into
           the device tree, we now have generic code to deal with this and it
           is used in two drivers so far.
      
         - Simplifications of the pin request conflict check.
      
         - Make dt_free_map() optional.
      
        Updates to drivers:
      
         - pinctrl-single now use the generic helpers to generate dynamic
           group and function tables from the device tree.
      
         - Texas Instruments IOdelay configuration driver add-on to
           pinctrl-single.
      
         - i.MX: use radix trees to store groups and functions, use the new
           generic group and function helpers to manage them.
      
         - Intel: add support for hardware debouncing and 1K pull-down. New
           subdriver for the Gemini Lake SoC.
      
         - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
           MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
      
         - Aspeed: use syscon cross-dependencies to set up related bits in the
           LPC host controller and display controller.
      
         - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
           Add banks Y, Z, AA, AB and AC.
      
         - AMD: support additional GPIO.
      
         - STM32: set this controller to strict muxing mode. STM32H743 MCU
           support.
      
         - Allwinner sunxi: deep simplifications on how to support subvariants
           of SoCs without adding to much SoC-specific data for each
           subvariant, especially for sun5i variants. New driver for V3s SoCs.
           New driver for the H5 SoC. Support A31/A31s variants with the new
           variant framework.
      
         - Mvebu: simplifications to use a MMIO and regmap abstraction. New
           subdrivers for the 98DX3236, 98DX5241 SoCs.
      
         - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
           driver to access regmaps. Add infrastructure for pin-bank retention
           control. Clean out the pin retention control from
           arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
           the Samsung pin control driver(s).
      
         - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
      
         - Qualcomm: use raw spinlock variants: this makes the qualcomm driver
           realtime-safe"

      HID: rmi: fallback to generic/multitouch if hid-rmi is not built · 2fa299a9
      Jiri Kosina authored
      Commit 279967a6 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi")
      unconditionally switches over handling of all Synaptics touchpads to hid-rmi
      (to make use of extended features of the HW); in case CONFIG_HID_RMI is
      disabled though this renders the touchpad unusable, as the
      
      	HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID)
      
      match doesn't exist and generic/multitouch doesn't bind to it either (due
      to hid group mismatch).
      
      Fix this by switching over to hid-rmi only if it has been actually built.

      Pull exception table module split from Paul Gortmaker:
       "Final extable.h related changes.
      
        This completes the separation of exception table content from the
        module.h header file. This is achieved with the final commit that
        removes the one line back compatible change that sourced extable.h
        into the module.h file.
      
        The commits are unchanged since January, with the exception of a
        couple Acks that came in for the last two commits a bit later. The
        changes have been in linux-next for quite some time[1] and have got
        widespread arch coverage via toolchains I have and also from
        additional ones the kbuild bot has.
      
        Maintaners of the various arch were Cc'd during the postings to
        lkml[2] and informed that the intention was to take the remaining arch
        specific changes and lump them together with the final two non-arch
        specific changes and submit for this merge window.
      
        The ia64 diffstat stands out and probably warrants a mention. In an
        earlier review, Al Viro made a valid comment that the original header
        separation of content left something to be desired, and that it get
        fixed as a part of this change, hence the larger diffstat"

      This reverts commit f2593cb1.
      
      Paul reported that this patch with older board-2.bin ath10k initialisation
      fails on Dell XPS 13:
      
      ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c,
      device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from
      ath10k/QCA6174/hw3.0/board-2.bin
      
      The reason is that the older board-2.bin does not have the variant version of
      the image name and ath10k does not fallback to the older naming scheme.

       - Add 'metadata2' feature to dm-cache to separate the dirty bitset out
         from other cache metadata. This improves speed of shutting down a
         large cache device (which implies writing out dirty bits).
      
       - Fix a memory leak during dm-stats data structure destruction.
      
       - Fix a DM multipath round-robin path selector performance regression
         that was caused by less precise balancing across all paths.
      
       - Lastly, introduce a DM core fix for a long-standing DM snapshot
         deadlock that is rooted in the complexity of the device stack used in
         conjunction with block core maintaining bios on current->bio_list to
         manage recursion in generic_make_request(). A more comprehensive fix
         to block core (and its hook in the cpu scheduler) would be wonderful

      usercopy: Add tests for all get_user() sizes · 4c5d7bc6
      Kees Cook authored
      The existing test was only exercising native unsigned long size
      get_user(). For completeness, we should check all sizes. But we
      must skip some 32-bit architectures that don't implement a 64-bit
      get_user().
      
      These new tests actually uncovered a bug in ARM's 64-bit get_user()

       - Various fixups and improvements to the above scheduling framework
         from Omar, Paolo, Bart, me, others.
      
       - Cleanup of the exported sysfs blk-mq data into debugfs, from Omar.
         This allows us to export more information that helps debug hangs or
         performance issues, without cluttering or abusing the sysfs API.
      
       - Fixes for the sbitmap code, the scalable bitmap code that was
         migrated from blk-mq, from Omar.
      
       - Removal of the BLOCK_PC support in struct request, and refactoring of
         carrying SCSI payloads in the block layer. This cleans up the code
         nicely, and enables us to kill the SCSI specific parts of struct
         request, shrinking it down nicely. From Christoph mainly, with help
         from Hannes.

         from Scott Bauer, with fixes/updates from various others folks.

         problems from Jan and Dan.
      
       - Set of fixes and updates for lightnvm, from Matias and Javier.

         workqueue deadlock fix on receive. Also marks Josef as the current
         maintainer of nbd.
      
       - Fix from Josef, overwriting queue settings when the number of
         hardware queues is updated for a blk-mq device.
      
       - NVMe fix from Keith, ensuring that we don't repeatedly mark and IO
         aborted, if we didn't end up aborting it.
      
       - SG gap merging fix from Ming Lei for block.

      It is implicitly included on x86 but not on arm and arm64 breaking the
      build if paravirtualization is used.  Since things from that header are
      used directly fix the build by putting the direct inclusion back.

      net: socket: fix recvmmsg not returning error from sock_error · e623a9e9
      Maxime Jayat authored
      Commit 34b88a68 ("net: Fix use after free in the recvmmsg exit path"),
      changed the exit path of recvmmsg to always return the datagrams
      variable and modified the error paths to set the variable to the error
      code returned by recvmsg if necessary.
      
      However in the case sock_error returned an error, the error code was
      then ignored, and recvmmsg returned 0.
      
      Change the error path of recvmmsg to correctly return the error code
      of sock_error.
      
      The bug was triggered by using recvmmsg on a CAN interface which was
      not up. Linux 4.6 and later return 0 in this case while earlier
      releases returned -ENETDOWN.

      ====================
      BPF fix with regards to unlocking
      
      This set fixes the issue Eric was reporting recently [1].
      First patch is a prerequisite discussed with Laura that is
      needed for the later fix in the second one. I've tested this
      extensively and it does not reproduce anymore on my side
      after the fix. Thanks & sorry about that!

      bpf: fix unlocking of jited image when module ronx not set · 9d876e79
      Daniel Borkmann authored
      Eric and Willem reported that they recently saw random crashes when
      JIT was in use and bisected this to 74451e66 ("bpf: make jited
      programs visible in traces"). Issue was that the consolidation part
      added bpf_jit_binary_unlock_ro() that would unlock previously made
      read-only memory back to read-write. However, DEBUG_SET_MODULE_RONX
      cannot be used for this to test for presence of set_memory_*()
      functions. We need to use ARCH_HAS_SET_MEMORY instead to fix this;
      also add the corresponding bpf_jit_binary_lock_ro() to filter.h.
      
      Fixes: 74451e66 ("bpf: make jited programs visible in traces")

      arch: add ARCH_HAS_SET_MEMORY config · d2852a22
      Daniel Borkmann authored
      Currently, there's no good way to test for the presence of
      set_memory_ro/rw/x/nx() helpers implemented by archs such as
      x86, arm, arm64 and s390.
      
      There's DEBUG_SET_MODULE_RONX and DEBUG_RODATA, however both
      don't really reflect that: set_memory_*() are also available
      even when DEBUG_SET_MODULE_RONX is turned off, and DEBUG_RODATA
      is set by parisc, but doesn't implement above functions. Thus,
      add ARCH_HAS_SET_MEMORY that is selected by mentioned archs,
      where generic code can test against this.
      
      This also allows later on to move DEBUG_SET_MODULE_RONX out of
      the arch specific Kconfig to define it only once depending on
      ARCH_HAS_SET_MEMORY.

      ====================
      net: mvpp2: misc improvements and preparation patches
      
      This series contains a number of fixes, misc improvements and
      preparation patches for an upcoming series that adds support for the
      new PPv2.2 network controller to the mvpp2 driver.
      
      The most significant improvements are:
      
       - Switching to using build_skb(), which is necessary for the upcoming
         PPv2.2 support, but anyway a good improvement to the current mvpp2
         driver (supporting PPv2.1).
      
       - Making the driver build on 64-bit platforms.
      
      Changes since v3:
      
       - Addition of a patch "net: mvpp2: fix DMA address calculation in
         mvpp2_txq_inc_put()", which fixes a bug in the driver in the
         calculation of DMA addresses. This bug was found using
         DMA_API_DEBUG.
      
       - Modify the "net: mvpp2: switch to build_skb() in the RX path" patch
         to recalculate the fragment size when the MTU is changed in
         mvpp2_bm_update_mtu().
      
       - Added Acked-by from Russell King on all patches, except:
      
          * "net: mvpp2: fix DMA address calculation in
            mvpp2_txq_inc_put()", because it's a new patch
      
          * "net: mvpp2: switch to build_skb() in the RX path" because I
            modified it since the v3.
      
       - Rebased on top of 4.10.
      
      Changes since v2:
      
       - Fix remaining 64-bit build warning, reported by David Miller.
      
       - Adjust how bit mask related definitions are done in "net: mvpp2:
         simplify MVPP2_PRS_RI_* definitions" according to Russell King
         suggestions.
      
       - Add a patch "net: mvpp2: remove useless arguments in
         mvpp2_rx_{pkts,time}_coal_set", suggested by Russell King.
      
       - Rework mvpp2_rx_time_coal_set() implementation to avoid overflows
         and rounding errors. I've used the implementation suggested by
         Russell King.
      
      Changes since v1:
      
       - This series is split as a separate series from the larger patch set
         adding support for PPv2.2 in the mvpp2 driver, as requested by
         David Miller.
      
       - Rebased on top of v4.10-rc1.

      net: mvpp2: enable building on 64-bit platforms · d3158807
      Thomas Petazzoni authored
      The mvpp2 is going to be extended to support the Marvell Armada 7K/8K
      platform, which is ARM64. As a preparation to this work, this commit
      enables building the mvpp2 driver on ARM64, by:
      
       - Adjusting the Kconfig dependency
      
       - Fixing the types used in the driver so that they are 32/64-bits
         compliant. We use dma_addr_t for DMA addresses, and unsigned long
         for virtual addresses.
      
      It is worth mentioning that after this commit, the driver is for now
      still only used on 32-bits platforms, and will only work on 32-bits
      platforms.

      net: mvpp2: switch to build_skb() in the RX path · 0e037281
      Thomas Petazzoni authored
      This commit adapts the mvpp2 RX path to use the build_skb() method. Not
      only build_skb() is now the recommended mechanism, but it also
      simplifies the addition of support for the PPv2.2 variant.
      
      Indeed, without build_skb(), we have to keep track for each RX
      descriptor of the physical address of the packet buffer, and the virtual
      address of the SKB. However, in PPv2.2 running on 64 bits platform,
      there is not enough space in the descriptor to store the virtual address
      of the SKB. So having to take care only of the address of the packet
      buffer, and building the SKB upon reception helps in supporting PPv2.2.
      
      The implementation is fairly straightforward:
      
       - mvpp2_skb_alloc() is renamed to mvpp2_buf_alloc() and no longer
         allocates a SKB. Instead, it allocates a buffer using the new
         mvpp2_frag_alloc() function, with enough space for the data and SKB.
      
       - The initialization of the RX buffers in mvpp2_bm_bufs_add() as well
         as the refill of the RX buffers in mvpp2_rx_refill() is adjusted
         accordingly.
      
       - Finally, the mvpp2_rx() is modified to use build_skb().
