Pull memory barrier for from Steven Rostedt: "The memory barrier usage in updating the random ptr hash for %p in vsprintf is incorrect. Instead of adding the read memory barrier into vsprintf() which will cause a slight degradation to a commonly used function in the kernel just to solve a very unlikely race condition that can only happen at boot up, change the code from using a variable branch to a static_branch. Not only does this solve the race condition, it actually will improve the performance of vsprintf() by removing the conditional branch that is only needed at boot" * tag 'trace-v4.17-rc5-vsprintf' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: vsprintf: Replace memory barrier with static_key for random_ptr_key update
