Pull locking updates from Ingo Molnar: "Core locking primitives updates: - Remove mutex_trylock_recursive() from the API - no users left - Simplify + constify the futex code a bit Lockdep updates: - Teach lockdep about local_lock_t - Add CONFIG_DEBUG_IRQFLAGS=y debug config option to check for potentially unsafe IRQ mask restoration patterns. (I.e. calling raw_local_irq_restore() with IRQs enabled.) - Add wait context self-tests - Fix graph lock corner case corrupting internal data structures - Fix noinstr annotations LKMM updates: - Simplify the litmus tests - Documentation fixes KCSAN updates: - Re-enable KCSAN instrumentation in lib/random32.c Misc fixes: - Don't branch-trace static label APIs - DocBook fix - Remove stale leftover empty file" * tag 'locking-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (24 commits) checkpatch: Don't check for mutex_trylock_recursive() locking/mutex: Kill mutex_trylock_recursive() s390: Use arch_local_irq_{save,restore}() in early boot code lockdep: Noinstr annotate warn_bogus_irq_restore() locking/lockdep: Avoid unmatched unlock locking/rwsem: Remove empty rwsem.h locking/rtmutex: Add missing kernel-doc markup futex: Remove unneeded gotos futex: Change utime parameter to be 'const ... *' lockdep: report broken irq restoration jump_label: Do not profile branch annotations locking: Add Reviewers locking/selftests: Add local_lock inversion tests locking/lockdep: Exclude local_lock_t from IRQ inversions locking/lockdep: Clean up check_redundant() a bit locking/lockdep: Add a skip() function to __bfs() locking/lockdep: Mark local_lock_t locking/selftests: More granular debug_locks_verbose lockdep/selftest: Add wait context selftests tools/memory-model: Fix typo in klitmus7 compatibility table ...
