Is NetBSD vulnerable to modern processor flaws

[Chuck Zmudzinski <frchuckz%gmail.com@localhost>]

Today news of critical vulnerabilities (for example, 
http://www.zdnet.com/article/google-reveals-trio-of-speculative-execution-flaws-says-amd-affected/ 
) affecting Intel and Arm and maybe AMD processors hit the press. News 
reports say all platforms using these chips, such as Linux, Microsoft, 
and Apple are affected since the flaw is in hardware but the fix must be 
made in the software operating system kernel. It has been reported that 
Linux developers say the fix involves fundamental changes to the way the 
Linux kernel handles virtual memory and they have been working on the 
fix for a while (see for example, 
http://www.zdnet.com/article/major-linux-redesign-in-the-works-to-deal-with-intel-chip-security-problem/ 
). I could not tell from NetBSD security documentation if NetBSD is 
vulnerable to these flaws or not or if work has been done in NetBSD to 
mitigate these security flaws in the hardware that NetBSD runs on. Can 
anyone say if NetBSD is vulnerable?
