      Linus Torvalds authored
      Pull gpio fixes from Bartosz Golaszewski:
       "Apart from some regular driver fixes there's a relatively big revert
        of the locking changes that were introduced to GPIOLIB in this merge
        window.
      
        This is because it turned out that some legacy GPIO interfaces - that
        need to translate a number from the global GPIO numberspace to the
        address of the relevant descriptor, thus running a GPIO device lookup
        and taking the GPIO device list lock - are still used in old code from
        atomic context resulting in "scheduling while atomic" errors.
      
        I'll try to make the read-only part of the list access entirely
        lockless using SRCU but this will take some time so let's go back to
        the old global spinlock for now.
      
        Summary:
      
         - revert the changes aiming to use a read-write semaphore to protect
           the list of GPIO devices due to calls to legacy API taking that
           lock from atomic context in old code
      
         - fix inverted logic in DEFINE_FREE() for GPIO device references
      
         - check the return value of bgpio_init() in gpio-mlxbf3
      
         - fix node address in the DT bindings example for gpio-xilinx

       - fix a duplicate cleanup in an error path introduced in

         In practise it doesn't happen - otherwise someone would have noticed
         since v5.17-rc1 I guess - because the device tree binding for the two
         drivers using of_pwm_single_xlate() only have args->args_count == 1.
      
         A device-tree that doesn't conform to the respective bindings could
         trigger that easily however.
      
       - correct the request callback of the jz4740 pwm driver which used
         dev_err_probe() long after .probe() completed.
      
         This is conceptually wrong because dev_err_probe() might call
         device_set_deferred_probe_reason() which is nonsensical after the
         driver is bound.

      Pull CXL (Compute Express Link) updates from Dan Williams:
       "The bulk of this update is support for enumerating the performance
        capabilities of CXL memory targets and connecting that to a platform
        CXL memory QoS class. Some follow-on work remains to hook up this data
        into core-mm policy, but that is saved for v6.9.
      
        The next significant update is unifying how CXL event records (things
        like background scrub errors) are processed between so called
        "firmware first" and native error record retrieval. The CXL driver
        handler that processes the record retrieved from the device mailbox is
        now the handler for that same record format coming from an EFI/ACPI
        notification source.
      
        This also contains miscellaneous feature updates, like Get Timestamp,
        and other fixups.
      
        Summary:
      
         - Add support for parsing the Coherent Device Attribute Table (CDAT)
      
         - Add support for calculating a platform CXL QoS class from CDAT data
      
         - Unify the tracing of EFI CXL Events with native CXL Events.
      
         - Add Get Timestamp support
      
         - Miscellaneous cleanups and fixups"

      Pull iommufd updates from Jason Gunthorpe:
       "This brings the first of three planned user IO page table invalidation
        operations:
      
         - IOMMU_HWPT_INVALIDATE allows invalidating the IOTLB integrated into
           the iommu itself. The Intel implementation will also generate an
           ATC invalidation to flush the device IOTLB as it unambiguously
           knows the device, but other HW will not.
      
        It goes along with the prior PR to implement userspace IO page tables
        (aka nested translation for VMs) to allow Intel to have full
        functionality for simple cases. An Intel implementation of the
        operation is provided.
      
        Also fix a small bug in the selftest mock iommu driver probe"
