stable/11 r329462 - Meltdown/Spectre MFC questions

[Mike Tancsa]

did a few simple buildworlds before and after on an Epyc box, and it had
no significant impact. Its vulnerable just to spectre.  I am just
updating an intel box to see the impact of the Meltdown fixes.  From
what I recall, apps that do a lot of system calls will have the largest
impact.
