Pull tty and serial driver fixes from Greg KH:
 "Here are some small tty and serial driver fixes for 6.8-rc3 that
  resolve a number of reported issues. Included in here are:

   - rs485 flag definition fix that affected the user/kernel abi in -rc1

   - max310x driver fixes

   - 8250_pci1xxxx driver off-by-one fix

   - uart_tiocmget locking race fix

  All of these have been in linux-next for over a week with no reported
  issues"

* tag 'tty-6.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty:
  serial: max310x: prevent infinite while() loop in port startup
  serial: max310x: fail probe if clock crystal is unstable
  serial: max310x: improve crystal stable clock detection
  serial: max310x: set default value when reading clock ready bit
  serial: core: Fix atomicity violation in uart_tiocmget
  serial: 8250_pci1xxxx: fix off by one in pci1xxxx_process_read_data()
  tty: serial: Fix bit order in RS485 flag definitions

Since the commit 93f3350c46fa ("RS485: fix inconsistencies in the
meaning of some variables"), the definition for bit 3 has been removed.
But with the switch to bit shift macros in commit 76ac8e29855b ("tty:
serial: Cleanup the bit shift with macro"), this gap wasn't preserved.
To avoid a break in user/kernel api of the system skip bit 3 again and
add a placeholder comment.

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"
