       "The major highlight this release is a refactoring of the core to allow
        us to run synchronous transfers in the context of the caller when

        very common case by eliminating context switches and reducing the
        number of hardware setup and teardown operations we need to perform.

      random: Fix fast_mix() function · 19acc77a
      George Spelvin authored
      There was a bad typo in commit 43759d4f ("random: use an improved
      fast_mix() function") and I didn't notice because it "looked right", so
      I saw what I expected to see when I reviewed it.
      
      Only months later did I look and notice it's not the Threefish-inspired
      mix function that I had designed and optimized.
      
      Mea Culpa.  Each input bit still has a chance to affect each output bit,
      and the fast pool is spilled *long* before it fills, so it's not a total
      disaster, but it's definitely not the intended great improvement.
      
      I'm still working on finding better rotation constants.  These are good
      enough, but since it's unrolled twice, it's possible to get better
      mixing for free by using eight different constants rather than repeating
      the same four.

      Merge tag 'trace-fixes-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
      
      Pull ftrace fixes from Steven Rostedt:
       "During testing Sedat Dilek hit a "suspicious RCU usage" splat that
        pointed out a real bug.  During suspend and resume the tlb_flush
        tracepoint is called when the CPU is going offline.  As the CPU has
        been noted as offline, RCU is ignoring that CPU, which means that it
        can not use RCU protected locks.  When tracepoints are activated, they
        require RCU locking, and if RCU is ignoring a CPU that runs a
        tracepoint, there is a chance that the tracepoint could cause
        corruption.
      
        The solution was to change the tracepoint into a
        TRACE_EVENT_CONDITION() which allows us to check a condition to
        determine if the tracepoint should be called or not.  If the condition
        is not met, the rcu protected code will not be executed.  By adding
        the condition "cpu_online(smp_processor_id())", this will prevent the
        RCU protected code from being executed if the CPU is marked offline.
      
        After adding this, another bug was discovered.  As RCU checks rcu
        callers, if a rcu call is not done, there is no check (obviously).  We
        found that tracepoints could be added in RCU ignored locations and not
        have lockdep complain until the tracepoint is activated.  This missed
        places where tracepoints were added in places they should not have
        been.  To fix this, code was added in 3.18 that if lockdep is enabled,
        any tracepoint will still call the rcu checks even if the tracepoint
        is not enabled.  The bug here, is that the check does not take the
        CONDITION into account.  As the condition may prevent tracepoints from
        being activated in RCU ignored areas (as the one patch does), we get
        false positives when we enable lockdep and hit a tracepoint that the
        condition prevents it from being called in a RCU ignored location.
      
        The fix for this is to add the CONDITION to the rcu checks, even if
        the tracepoint is not enabled"
