Linus Torvalds 9ba19ccd2d These were the main changes in this cycle:
- LKMM updates: mostly documentation changes, but also some new litmus tests for atomic ops.
 
  - KCSAN updates: the most important change is that GCC 11 now has all fixes in place
                   to support KCSAN, so GCC support can be enabled again. Also more annotations.
 
  - futex updates: minor cleanups and simplifications
 
  - seqlock updates: merge preparatory changes/cleanups for the 'associated locks' facilities.
 
  - lockdep updates:
     - simplify IRQ trace event handling
     - add various new debug checks
     - simplify header dependencies, split out <linux/lockdep_types.h>, decouple
       lockdep from other low level headers some more
     - fix NMI handling
 
  - misc cleanups and smaller fixes
