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.

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"

regulator: Fix !REGULATOR builds of systems using system suspend calls

The system suspend calls (used to synchronize between system suspend of
the CPU and it's PMIC) are called from board code but not stubbed when
regulator is disabled causing build failures in such cases.  This patch
fixes those build failures.

When taking a CPU down for suspend and resume, a tracepoint may be called
when the CPU has been designated offline. As tracepoints require RCU for
protection, they must not be called if the current CPU is offline.

Unfortunately, trace_tlb_flush() is called in this scenario as was noted
by LOCKDEP:

By converting the tlb_flush tracepoint to a TRACE_EVENT_CONDITION where the
condition is cpu_online(smp_processor_id()), we can avoid calling RCU protected
code when the CPU is offline.

The trace_tlb_flush() tracepoint can be called when a CPU is going offline.
When a CPU is offline, RCU is no longer watching that CPU and since the
tracepoint is protected by RCU, it must not be called. To prevent the
tlb_flush tracepoint from being called when the CPU is offline, it was
converted to a TRACE_EVENT_CONDITION where the condition checks if the
CPU is online before calling the tracepoint.

Unfortunately, this was not enough to stop lockdep from complaining about
it. Even though the RCU protected code of the tracepoint will never be
called, the condition is hidden within the tracepoint, and even though the
condition prevents RCU code from being called, the lockdep checks are
outside the tracepoint (this is to test tracepoints even when they are not
enabled).

Even though tracepoints should be checked to be RCU safe when they are not
enabled, the condition should still be considered when checking RCU.
