Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Ingo Molnar: "The sole purpose of these changes is to shrink and simplify the RCU code base, which has suffered from creeping bloat over the past couple of years. The end result is a net removal of ~2700 lines of code: 79 files changed, 1496 insertions(+), 4211 deletions(-) Plus there's a marked reduction in the Kconfig space complexity as well, here's the number of matches on 'grep RCU' in the .config: before after x86-defconfig 17 15 x86-allmodconfig 33 20" * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (86 commits) rcu: Remove RCU CPU stall warnings from Tiny RCU rcu: Remove event tracing from Tiny RCU rcu: Move RCU debug Kconfig options to kernel/rcu rcu: Move RCU non-debug Kconfig options to kernel/rcu rcu: Eliminate NOCBs CPU-state Kconfig options rcu: Remove debugfs tracing srcu: Remove Classic SRCU srcu: Fix rcutorture-statistics typo rcu: Remove SPARSE_RCU_POINTER Kconfig option rcu: Remove the now-obsolete PROVE_RCU_REPEATEDLY Kconfig option rcu: Remove typecheck() from RCU locking wrapper functions rcu: Remove #ifdef moving rcu_end_inkernel_boot from rcupdate.h rcu: Remove nohz_full full-system-idle state machine rcu: Remove the RCU_KTHREAD_PRIO Kconfig option rcu: Remove *_SLOW_* Kconfig options srcu: Use rnp->lock wrappers to replace explicit memory barriers rcu: Move rnp->lock wrappers for SRCU use rcu: Convert rnp->lock wrappers to macros for SRCU use rcu: Refactor #includes from include/linux/rcupdate.h bcm47xx: Fix build regression ...
