Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-coregrafted

Pull driver core fixes from Danilo Krummrich:

 - Fix kernfs listxattr() not returning security xattr names (e.g.
   SELinux labels) when the kernfs node has no allocated kernfs_iattrs

 - Fix silent truncation of IRQ vector indices in the Rust PCI
   abstractions

 - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is
   disabled instead of silently enabling extra kernel functionality

 - Russ Weight is retiring from kernel development; update the Firmware
   Loader sysfs contact to the driver-core mailing list, add a CREDITS
   entry for Firmware Upload, and update MAINTAINERS accordingly

* tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core:
  MAINTAINERS: Remove Russ Weight from Firmware Loader
  CREDITS: Add CREDITS entry for Firmware Upload
  firmware_loader: Change contact for sysfs nodes
  rust: pci: reject IRQ vector indices that do not fit in u32
  kernfs: preserve security xattrs without allocating iattrs
  drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF

+config LIGHTWEIGHT_SPINLOCK_CHECK
+	bool "Enable lightweight spinlock checks"
+	depends on DEBUG_KERNEL && SMP && !DEBUG_SPINLOCK
+	default y
+	help
+	  Add checks with low performance impact to the spinlock functions
+	  to catch memory overwrites at runtime. For more advanced
+	  spinlock debugging you should choose the DEBUG_SPINLOCK option
+	  which will detect unitialized spinlocks too.
+	  If unsure say Y here.

+config TLB_PTLOCK
+	bool "Use page table locks in TLB fault handler"
+	depends on DEBUG_KERNEL && SMP
+	default n
+	help
+	  Select this option to enable page table locking in the TLB
+	  fault handler. This ensures that page table entries are
+	  updated consistently on SMP machines at the expense of some
+	  loss in performance.
