I found the problem, CONFIG_HOTPLUG_SMT is enable due to CONFIG_SMP, but I did explicitly enable CONFIG_HOTPLUG_CPU.
That's why the smt dir is missing, and kernel panic when I boot with 'nosmt' or 'l1tf=full' probably also other combination.
With CONFIG_HOTPLUG_CPU=y, it works fine so far.
So do we need a new configuration dependancy here to resolve this problem? Why is this not an issue in Linus's tree?
That's probably the same problem on Linus tree. Have not tested it yet though. I'll have a look.
