Linus Torvalds 22a39c3d86 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.
