Matt Dillon: Intel Meltdown bug mitigation in master, performance effects

Matt Dillon hardly needs an introduction, however, I'd just like to point out that he's one of the few folks that I trust on estimating these CPU bugs, as back in 2012, he actually found a bug in AMD CPUs that resulted in an erratum from the vendor:

He was also involved in providing a public analysis of the Intel Core bugs back in 2007:

Has anything come out of the OpenBSD community about this? I've searched but can't seem to find any official statements.
