Here's the meat of the conclusion:

"While AMD is not currently aware of any code that would be considered vulnerable due to PSF behavior, this whitepaper examines the potential security implications of PSF, in general, as well as mechanisms that are designed to disable the feature if desired. AMD believes that for most applications, the security risk of PSF is likely low and where isolation is required, techniques such as address space isolation are preferred over software sandboxing."

"AMD recommends leaving the Predictive Store Forwarding feature enabled as the default setting."
