  Linux 6.2-rc4
  kbuild: Fix CFI hash randomization with KASAN
  firmware: coreboot: Check size of table entry and use flex-array
  kallsyms: Fix scheduling with interrupts disabled in self-test
  ata: pata_cs5535: Don't build on UML
  lockref: stop doing cpu_relax in the cmpxchg loop
  x86/pci: Treat EfiMemoryMappedIO as reservation of ECAM space
  efi: tpm: Avoid READ_ONCE() for accessing the event log
  io_uring: lock overflowing for IOPOLL
  ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF
  iommu/mediatek-v1: Fix an error handling path in mtk_iommu_v1_probe()
  iommu/iova: Fix alloc iova overflows issue
  iommu: Fix refcount leak in iommu_device_claim_dma_owner
  iommu/arm-smmu-v3: Don't unregister on shutdown
  iommu/arm-smmu: Don't unregister on shutdown
  iommu/arm-smmu: Report IOMMU_CAP_CACHE_COHERENCY even betterer
  platform/x86: thinkpad_acpi: Fix profile mode display in AMT mode
  ALSA: usb-audio: Fix possible NULL pointer dereference in snd_usb_pcm_has_fixed_rate()
  platform/x86: int3472/discrete: Ensure the clk/power enable pins are in output mode
