Subject: [GIT PULL] Locking updates for v6.0

Linus,

Please pull the latest locking/core git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git locking-core-2022-08-01

   # HEAD: eae6d58d67d9739be5f7ae2dbead1d0ef6528243 locking/lockdep: Fix lockdep_init_map_*() confusion

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.

 Thanks,

	Ingo

      jump_label: s390: avoid pointless initial NOP patching
      jump_label: mips: move module NOP patching into arch code
      jump_label: make initial NOP patching the special case
