Pull RCU updates from Thomas Gleixner: "RCU, LKMM and KCSAN updates collected by Paul McKenney. RCU: - Avoid cpuinfo-induced IPI pileups and idle-CPU IPIs - Lockdep-RCU updates reducing the need for __maybe_unused - Tasks-RCU updates - Miscellaneous fixes - Documentation updates - Torture-test updates KCSAN: - updates for selftests, avoiding setting watchpoints on NULL pointers - fix to watchpoint encoding LKMM: - updates for documentation along with some updates to example-code litmus tests" * tag 'core-rcu-2020-12-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (72 commits) srcu: Take early exit on memory-allocation failure rcu/tree: Defer kvfree_rcu() allocation to a clean context rcu: Do not report strict GPs for outgoing CPUs rcu: Fix a typo in rcu_blocking_is_gp() header comment rcu: Prevent lockdep-RCU splats on lock acquisition/release rcu/tree: nocb: Avoid raising softirq for offloaded ready-to-execute CBs rcu,ftrace: Fix ftrace recursion rcu/tree: Make struct kernel_param_ops definitions const rcu/tree: Add a warning if CPU being onlined did not report QS already rcu: Clarify nocb kthreads naming in RCU_NOCB_CPU config rcu: Fix single-CPU check in rcu_blocking_is_gp() rcu: Implement rcu_segcblist_is_offloaded() config dependent list.h: Update comment to explicitly note circular lists rcu: Panic after fixed number of stalls x86/smpboot: Move rcu_cpu_starting() earlier rcu: Allow rcu_irq_enter_check_tick() from NMI tools/memory-model: Label MP tests' producers and consumers tools/memory-model: Use "buf" and "flag" for message-passing tests tools/memory-model: Add types to litmus tests tools/memory-model: Add a glossary of LKMM terms ...
