Linus Torvalds 7be4bc52fd Driver core changes for 7.4-rc1
- core:
 
   - Add TAINT_FORCED_BIND to taint the kernel and driver module before manual
     sysfs bind/unbind operations; make add_taint_module() available to
     driver core and update taint decoding tools and documentation
 
   - Constify device_show/store_*() attribute parameters and adapt x86 MCE and
     perf users to prepare for const dev_ext_attribute instances
 
   - Fix UAF in NUMA access node registration failure handling by dropping
     the device reference with put_device() instead of directly freeing the node
 
 - debugfs:
 
   - Make debugfs_create_str() read-only to eliminate double-free races between
     concurrent writers; reject writable modes; convert interconnect and
     SoundWire users to local file operations with mutex-protected strings
 
 - kobject:
 
   - Fix out-of-bounds access in kobject_action_type() when parsing action
     strings containing embedded NUL bytes
 
   - Fix the kobject_set_name() reference in kset_register() kernel-doc
 
 - Rust:
 
   - DMA:
 
     - Tie Coherent, CoherentBox and CoherentHandle to the device's bound
       lifetime to prevent retaining DMA allocations beyond driver unbind;
       propagate the lifetime through nova-core and the DMA sample driver
 
   - I/O:
 
     - Require explicit base types for registers and replace relative registers
       with typed subregion projections; reimplement register!() as a proc
       macro, support registers using existing types without inline bitfields,
       and convert nova-core, Tyr and the PCI sample; add AsRepr/AsReprMut and
       transmute helpers with deferred size checks for representation
       conversions
 
     - Wrap ResourceSize in a transparent newtype with explicit conversions,
       including checked conversion to usize
 
   - PCI:
 
     - Add typed PCIe extended capability lookup and SR-IOV accessors for the
       First VF Offset and decoded VF BAR addresses and widths, keeping raw
       SR-IOV registers private to preserve PCI core ownership of their state
 
   - scatterlist:
 
     - Honor the device's maximum segment size as well as the DMA mapping limit
       when constructing SG tables
 
     - Return u32 from SGEntry::dma_len() to match the C segment length type
 
   - misc:
 
     - Validate auxiliary DeviceId name length explicitly to improve
       compile-time diagnostics for oversized device ID table entries
 
     - Drop unnecessary 'static bounds from debugfs ScopedDir file creation
       methods to support data containing non-'static references, including DMA
       buffers
 
 - misc:
 
   - Add Johan Hovold as driver core maintainer
 
   - Simplify platform_device_alloc() by returning early on allocation failure
 
   - Fix typos in driver core and kernfs comments
