Pull lockdep fix from Thomas Gleixner:
"A RT fix for lockdep.
lockdep invokes prandom_u32() to create cookies. This worked until
prandom_u32() was switched to the real random generator, which takes a
spinlock for extraction, which does not work on RT when invoked from
atomic contexts.
lockdep has no requirement for real random numbers and it turns out
sched_clock() is good enough to create the cookie. That works
everywhere and is faster"
