What happens on a Xen kernel if these lines are not there?
Does Xen export the C-states tables to Dom0 kernel, and the Dom0
kernel has an acpi processor driver, and thus it would try to
use all the C-states?

If yes, must Xen show those tables to Dom?
If it did not, then the lines above would not be necessary,
as in the absence of any C-states, the kernel should
use halt by default.
