We need to be careful to not promote or demote the memory containing the per-CPU structures as the exception handlers will dereference it so any time it's invalid may cause recursive exceptions. Add a new pmap function to set a flag in the pte marking memory that cannot be promoted or demoted and use it to mark pcpu memory.
