New bug resurface.
What is the command to test AMD CUP's if flag: X86_BUG_CPU_INSECURE is
enabled?

ALL CPUs are vulnerable to Spectre. The vuln described in your link is
Meltdown and only Intel is vulnerable to that.

I don't believe there is a fix for Spectre, but it is also much tougher to
mount and attack. Meltdown on the other-hand has a fix that will likely
reduce performace, but only needs to be applied for Intel CPUs.
