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. Signed-off-by:

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" * tag 'trace-fixes-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: x86/tlb/trace: Do not trace on CPU that is offline tracing: Add condition check to RCU lockdep checks

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.
