      Pull USB/Thunderbolt/PHY driver updates from Greg KH:
       "Here is the big USB and Thunderbolt and PHY driver updates for
        5.6-rc1.
      
        With the advent of USB4, "Thunderbolt" has really become USB4, so the
        renaming of the Kconfig option and starting to share subsystem code
        has begun, hence both subsystems coming in through the same tree here.
      
        PHY driver updates also touched USB drivers, so that is coming in
        through here as well.
      
        Major stuff included in here are:
         - USB 4 initial support added (i.e. Thunderbolt)
         - musb driver updates
         - USB gadget driver updates
         - PHY driver updates
         - USB PHY driver updates
         - lots of USB serial stuff fixed up
         - USB typec updates
         - USB-IP fixes
         - lots of other smaller USB driver updates
      
        All of these have been in linux-next for a while now (the usb-serial
        tree is already tested in linux-next on its own before merged into
        here), with no reported issues"

        that causes configuration warnings    - Linus ]

      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes, nothing too exciting about
        this.
      
        Some changes hit arch/sh and arch/arm but are well isolated and
        acknowledged by the respective arch maintainers.
      
        Core changes:
      
         - Dropped the chained IRQ setup callback into GPIOLIB as we got rid
           of the last users of that in this changeset.
      
        New drivers:
      
         - New driver for Ingenic X1830.
      
         - New driver for Freescale i.MX8MP.
      
        Driver enhancements:
      
         - Fix all remaining Intel drivers to pass their IRQ chips along with
           the GPIO chips.
      
         - Intel Baytrail allocates its irqchip dynamically.
      
         - Intel Lynxpoint is thoroughly rewritten and modernized.
      
         - Aspeed AST2600 pin muxing and configuration is much improved.
      
         - Qualcomm SC7180 functions are updated and wakeup interrupt map is
           provided.
      
         - A whole slew of Renesas SH-PFC cleanups and improvements.
      
         - Fix up the Intel DT bindings to use the generic YAML DT bindings
           schema (a first user of this)"

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.6 kernel cycle.
      
        This is a pretty calm cycle so far, nothing special going on really.
        Some more changes will come in from the irqchip and pin control trees.
      
        I also deleted an orphan include file for FMC that was dangling since
        subsystem was removed.
      
        Core changes:
      
         - Document the usecases for the kernelspace vs userspace handling of
           GPIOs.
      
         - Handle MSI (message signalled interrupts) properly in the core
           hierarchical irqdomain code.
      
         - Fix a rare race condition while initializing the descriptor array.
      
        New drivers:
      
         - Xylon LogiCVC GPIO driver.
      
         - WDC934x GPIO controller driver.
      
        Driver improvements:
      
         - Implemented suspend/resume in the Tegra driver.
      
         - MPC8xx edge detection fixup.
      
         - Properly convert ThunderX to use hierarchical irqdomain with
           GPIOLIB_IRQCHIP on top of the revert of the previous buggy
           switchover. This time it works (hopefully).
      
        Misc:
      
         - Drop a FMC remnant file <linux/ipmi-fru.h>
      
         - A slew of fixes"

      Pull IMA updates from Mimi Zohar:
       "Two new features - measuring certificates and querying IMA for a file
        hash - and three bug fixes:
      
         - Measuring certificates is like the rest of IMA, based on policy,
           but requires loading a custom policy. Certificates loaded onto a
           keyring, for example during early boot, before a custom policy has
           been loaded, are queued and only processed after loading the custom
           policy.
      
         - IMA calculates and caches files hashes. Other kernel subsystems,
           and possibly kernel modules, are interested in accessing these
           cached file hashes.
      
        The bug fixes prevent classifying a file short read (e.g. shutdown) as
        an invalid file signature, add a missing blank when displaying the
        securityfs policy rules containing LSM labels, and, lastly, fix the
        handling of the IMA policy information for unknown LSM labels"

      Linus Torvalds authored
      Pull sound updates from Takashi Iwai:
       "As the diffstat shows we've had again a lot of works done for this
        cycle: the majority of changes are the continued componentization and
        code refactoring in ASoC, the tree-wide PCM API updates and cleanups
        and SOF updates while a few ASoC driver updates are seen, too.
      
        Here we go, some highlights:
      
        Core:
         - Finally y2038 support landed to ALSA ABI; some ioctls have been
           extended and lots of tricks were applied
         - Applying the new managed PCM buffer API to all drivers; the API
           itself was already merged in 5.5
         - The already deprecated dimension support in ALSA control API is
           dropped completely now
         - Verification of ALSA control elements to catch API misuses
      
        ASoC:
         - Further code refactorings and moving things to the component level
         - Lots of updates and improvements on SOF / Intel drivers; now
           including common HDMI driver and SoundWire support
         - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
           WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
           RT1015 and RT1308
      
        HD-audio:
         - Improved ring-buffer communications using waitqueue
         - Drop the superfluous buffer preallocation on x86
      
        Others:
         - Many code cleanups, mostly constifications over the whole tree

      Pull btrfs updates from David Sterba:
       "Features, highlights:
      
         - async discard
             - "mount -o discard=async" to enable it
             - freed extents are not discarded immediatelly, but grouped
               together and trimmed later, with IO rate limiting
             - the "sync" mode submits short extents that could have been
               ignored completely by the device, for SATA prior to 3.1 the
               requests are unqueued and have a big impact on performance
             - the actual discard IO requests have been moved out of
               transaction commit to a worker thread, improving commit latency
             - IO rate and request size can be tuned by sysfs files, for now
               enabled only with CONFIG_BTRFS_DEBUG as we might need to
               add/delete the files and don't have a stable-ish ABI for
               general use, defaults are conservative
      
         - export device state info in sysfs, eg. missing, writeable
      
         - no discard of extents known to be untouched on disk (eg. after
           reservation)
      
         - device stats reset is logged with process name and PID that called
           the ioctl
      
        Fixes:
      
         - fix missing hole after hole punching and fsync when using NO_HOLES
      
         - writeback: range cyclic mode could miss some dirty pages and lead
           to OOM
      
         - two more corner cases for metadata_uuid change after power loss
           during the change
      
         - fix infinite loop during fsync after mix of rename operations
      
        Core changes:
      
         - qgroup assign returns ENOTCONN when quotas not enabled, used to
           return EINVAL that was confusing
      
         - device closing does not need to allocate memory anymore
      
         - snapshot aware code got removed, disabled for years due to
           performance problems, reimplmentation will allow to select wheter
           defrag breaks or does not break COW on shared extents
      
         - tree-checker:
             - check leaf chunk item size, cross check against number of
               stripes
             - verify location keys for DIR_ITEM, DIR_INDEX and XATTR items
      
         - new self test for physical -> logical mapping code, used for super
           block range exclusion
      
         - assertion helpers/macros updated to avoid objtool "unreachable
           code" reports on older compilers or config option combinations"

      udp: segment looped gso packets correctly · 6cd021a5
      Willem de Bruijn authored
      Multicast and broadcast packets can be looped from egress to ingress
      pre segmentation with dev_loopback_xmit. That function unconditionally
      sets ip_summed to CHECKSUM_UNNECESSARY.
      
      udp_rcv_segment segments gso packets in the udp rx path. Segmentation
      usually executes on egress, and does not expect packets of this type.
      __udp_gso_segment interprets !CHECKSUM_PARTIAL as CHECKSUM_NONE. But
      the offsets are not correct for gso_make_checksum.
      
      UDP GSO packets are of type CHECKSUM_PARTIAL, with their uh->check set
      to the correct pseudo header checksum. Reset ip_summed to this type.
      (CHECKSUM_PARTIAL is allowed on ingress, see comments in skbuff.h)

      The old netem mailing list was inactive and recently was targeted by
      spammers. Switch to just using netdev mailing list which is where all
      the real change happens.

      Pull irq updates from Thomas Gleixner:
       "The interrupt departement provides:
      
         - A mechanism to shield isolated tasks from managed interrupts:
      
           The affinity of managed interrupts is completely controlled by the
           kernel and user space has no influence on them. The reason is that
           the automatically assigned affinity correlates to the multi-queue
           CPU handling of block devices.
      
           If the generated affinity mask spaws both housekeeping and isolated
           CPUs the interrupt could be routed to an isolated CPU which would
           then be disturbed by I/O submitted by a housekeeping CPU.
      
           The new mechamism ensures that as long as one housekeeping CPU is
           online in the assigned affinity mask the interrupt is routed to a
           housekeeping CPU.
      
           If there is no online housekeeping CPU in the affinity mask, then
           the interrupt is routed to an isolated CPU to keep the device queue
           intact, but unless the isolated CPU submits I/O by itself these
           interrupts are not raised.
      
         - A small addon to the device tree irqdomain core code to avoid
           duplication in irq chip drivers
      
         - Conversion of the SiFive PLIC to hierarchical domains
      
         - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI,
           NXP INTMUX, Meson A1 GPIO
      
         - The first cut of support for the new ARM GICv4.1
      
         - The usual pile of fixes and improvements in core and driver code"
