Merge tag 'locking-core-2022-08-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar: "This was a fairly quiet cycle for the locking subsystem: - lockdep: Fix a handful of the more complex lockdep_init_map_*() primitives that can lose the lock_type & cause false reports. No such mishap was observed in the wild. - jump_label improvements: simplify the cross-arch support of initial NOP patching by making it arch-specific code (used on MIPS only), and remove the s390 initial NOP patching that was superfluous" * tag 'locking-core-2022-08-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: locking/lockdep: Fix lockdep_init_map_*() confusion jump_label: make initial NOP patching the special case jump_label: mips: move module NOP patching into arch code jump_label: s390: avoid pointless initial NOP patching
