Linux4.20針對Meltdown/Spectre/..修正 - 3C

Revert "x86/speculation: Enable cross-hyperthread spectre v2 STIBP mitigation"

It's not ready for the stable trees as there are major slowdowns involved with t
his patch.

簡而言之可說補洞的代價太大了...

目前
4.19.4
https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.4
和
4.14.83
https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.83
撤回STIBP
是否加回來或還能怎麼改
有待觀察

這真是場災難...
