Linus Torvalds 2da2ca24a3 Merge branch 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip ... Pull locking fixes from Thomas Gleixner: "A set of fixes and updates for the locking code: - Prevent lockdep from updating irq state within its own code and thereby confusing itself. - Buid fix for older GCCs which mistreat anonymous unions - Add a missing lockdep annotation in down_read_non_onwer() which causes up_read_non_owner() to emit a lockdep splat - Remove the custom alpha dec_and_lock() implementation which is incorrect in terms of ordering and use the generic one. The remaining two commits are not strictly fixes. They provide irqsave variants of atomic_dec_and_lock() and refcount_dec_and_lock(). These are required to merge the relevant updates and cleanups into different maintainer trees for 4.19, so routing them into mainline without actual users is the sanest approach. They should have been in -rc1, but last weekend I took the liberty to just avoid computers in order to regain some mental sanity" * 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: locking/qspinlock: Fix build for anonymous union in older GCC compilers locking/lockdep: Do not record IRQ state within lockdep code locking/rwsem: Fix up_read_non_owner() warning with DEBUG_RWSEMS locking/refcounts: Implement refcount_dec_and_lock_irqsave() atomic: Add irqsave variant of atomic_dec_and_lock() alpha: Remove custom dec_and_lock() implementation		2018-06-24 19:36:16 +08:00
