kernel - Zen 2 - Make sure %fs's selector is loaded in AP bootstrap * Issue load_fs() in the AP bootstrap. It appears that Zen 2 handles %fs in a weird way when the selector isn't loaded, causing the first wrmsr(MSR_FSBASE) to quietly fail, and possibly others too. * For good measure, also issue load_ds() and load_es(). * Fixes DragonFlyBSD's boot on Zen 2.
